Chapter 1 —Installation Steering Guide 9

CHAPTER 1 — INSTALLATION STEERING GUIDE

This manual describes the PET MINItrace Production System installation process, up to, but not including, the Performance Demonstration and customer acceptance.

1-1 IntroductionUse this chapter as a general guide to the installation. The Installation Steering Guide provides a brief description of each phase of the installation, and the location of the detailed instructions elsewhere in the manual. The instructions include boxes to check when you complete each subsection or step. The final six chapters are laid out in a logi-cal sequence, so that each chapter covers a phase of the installation:

• Chapter 2 - page 15






This manual also contains several appendices that contain tables to record start-up val-ues or other information used by one or more chapters.

Note: Some sites are literally built around the cyclotron, so several weeks may elapse between the system delivery and the actual start of the installation. The customer must provide secure storage for the rest of the system, and arrange for the riggers to come back to move the heavy components into place.

During a MINItrace system installation, you have to:

• Unpack and rig the major system components.

• Assemble the fixed shields, position the magnet and attach the shield doors.

• Position the components and attach the support cabinets to the shield.

• Run the power and signal cables.

• Run the hoses, compressed air, gas and product pipes or tubes.

• Attach the Target cooling panel, diffusion pump and vacuum rotary pump to the magnet.

• Make the connections to the MINItrace components.

• Start-up the system.

• Run the initial beam tests, and check the system function.

• Run the Performance Demonstration for customer acceptance.



10 Chapter 1 —Installation Steering Guide

This manual contains instructions for everything except performance demonstration.

1-2 Installation OverviewUse Table 1-1 to track the system installation. Within the chapters, each section, sub-section or step contains a checkbox to mark when you complete the corresponding instruction. When you finish one of the major tasks listed in Table 1-1 , make a check mark in the corresponding box. That way, a new person can quickly determine how far the installation has proceeded, and what tasks remain unfinished.

If this is the your first MINItrace installation, follow the procedures in the order they appear in this manual. If you have previous MINItrace installation experience, you may vary the installation sequence. If you have a team of installers on site, you may assign tasks, and work independently. For instance, one person could assemble the target side of the magnet while another person (or team) attaches the diffusion pump.

Note: Refer to Illustration 1-1. All "right" and "left" shield and support cabinet locations are referenced from the front of the MINItrace.

Notes and Comments:



Chapter 2 —Unpack the System 15

CHAPTER 2 — UNPACK THE SYSTEM

Hire experienced riggers, a crane, and operator to:

• Unpack the MINItrace system.

• Move the large components into position.

• Assemble the rear shields.

• Move the magnet into its niche.

• Help attach the shield doors.

The MINItrace Electronics cabinets (RFPG and CCAB) and Support Cabinets arrive com-pletely assembled, and packed in crates. Additional crates contain specialized rigging equipment, installation tools, cables and cyclotron subsystems, to be assembled on site. You don’t have to unpack all the crates during the rigging process, but you need a crane and riggers to move these crates to the Cyclotron room, or another secure location.

2-1 Recommended Handling Procedures

2-1-1 Riggers’ Responsibilities

• Unpack the magnet and shields.

• Move the magnet into a temporary location in the Cyclotron room.

• Unpack the shields.

• Assemble the rear (fixed) shields and move the magnet into place.

• Help attach the shield doors to the rear shields.

• Uncrate the CSC and TSC support cabinets and move them into the room.

• Uncrate and move the RFPG and CCAB into the room.

Recommended: Rent an appliance dolly to move the CCAB (no wheels).

• Move the rest of the crates and boxes into a secure area in or near the PET suite.

Recommended: It you can’t store the crates in a secure area, rent a 40-ft shipping container for use as a staging area and temporary storage.

• Remove all the shipping materials from the containers and reattach the tops.

• Remove the packing materials and empty crates from the site.



16 Chapter 2 —Unpack the System

2-1-2 Site Representative’s Responsibilities

The FE or Installation representative has the following responsibilities:

• Oversee the unpacking and positioning of the major components.

• Inventory the crate contents and check for excessive damage.

• The system should arrive with a packing list attached to the cyclotron magnet.

• Inventory the cables. The cables are currently bundled and packaged by MIS group number. Each box in Crate 7 and 8 contains a separate MIS run. Appendix A con-tains a MIS Map, tables of cable information, the cable list , and a list of system des-ignators (acronyms) and definitions.

Note: Expect the shields to look a little rough when they come out of the containers. (Illustration 2-1) The system arrives with paint and supplies to repair chips and cracks in the shield.

2-1-3 Installation Tool Box (Gang box)

Arrange for the secure storage of the wooden MINItrace installation gang box. (Part number 2230305)

Refer to Illustration 2-3. The gang box is considered a Regional tool. It contains the tools and hardware you’ll need to install the MINItrace system. The box contains an assort-ment of spare hardware and wall anchors to accommodate a variety of wall finishes. Inventory the contents at the beginning and end of the installation. Restock the items you used during the installation BEFORE you return the gang box.

The gang box should arrive with a complete inventory list . Make sure the box contains enough hardware and drill bits to complete the installation. A consumables kit is sent separately.

ILLUSTRATION 2-3INSTALLATION TOOL BOX (GANG BOX) - 3/4 AND SIDE VIEWS

The gang box contains power tools and tool boxes filled with metric hand tools. In the-ory, it contains everything you need to install the system. REMEMBER to return the hand tools to the individual tool boxes each night, and lock the box each time you leave the site.




2-2 Required Installation ToolsIn addition to the usual service tool kit , you’ll need the following items to install the MINI-trace system:

• The MINItrace Installation Gang Box, part number 2230305 (Refer to Illustration 2-3)

• Rigging box (part number 2298267), see section 2-4-1 (Ships with the system as Crate #16, or arrives separately from GEMSA or GEMSAM)

• Hand-truck, or pallet-jack with narrow forks (Refer to Illustration 2-4) The forks must be 65cm wide, or less, to accommodate a European pallet.

• Appliance dolly to position the CCAB (Refer to Illustration 2-4) Rent one with solid rubber tires and built-in load binding straps.

• Aluminum platform ladder

ILLUSTRATION 2-4HYDRAULIC PALLET-JACK WITH NARROW FORKS AND APPLIANCE DOLLY

65cm or less




2-3 Check for Transit DamageCheck the shipping containers for physical damage when they arrive on site. In Illustration 2-5, the shield shifted about 5cm during transit , enough to damage the container doors and break the dimensional lumber used to secure it during shipment. Also check the crate exteriors for damage as the riggers unload them from the shipping container.

• Inspect the containers when they are delivered. Immediately report any damage to the driver/freight handler and your local installation specialist .

ILLUSTRATION 2-5DAMAGED SHIPPING CONTAINER




2-4 Unpacking InstructionsYou have two objectives during this phase of the installation:

• Remove the system components from their trucks or shipping containers.

• Position (stage) the components in the unloading area for efficient access and transfer into the Cyclotron room or to more secure storage.

Use a heavy mobile crane to unload the MINItrace system and crates from the truck or shipping container. Position the crane as close as possible to the facility entrance or access hole. Choose the most direct delivery route from the entrance to the Cyclotron room, as corners can be difficult to negotiate.

For best results: Reserve a 5000 sq-ft area near the facility entrance to unload and stage the system components for delivery to the cyclotron room. This area includes space for the crane, truck and its shipping container or trailer.

ILLUSTRATION 2-6RESERVE A 5000 SQ-FT UNLOADING AREA

In Europe, the MINItrace system arrives crated, on three trucks. Elsewhere, the MINItrace system arrives in three 20-ft shipping containers with removable tops.

To remove the MINItrace crates and components from the shipping container:

• Open the doors and use a forklift or skid loader with at least a 50 ton capacity to remove the crates and components from the shipping container.

• Recommended: Remove the tarp from the top of the container, and use a 60-80 ton crane to remove the magnet and shields (vertically) from the shipping container.




ILLUSTRATION 2-7REMOVE THE TARP FROM THE TOP OF THE CONTAINER

ILLUSTRATION 2-8DISASSEMBLE AND SALVAGE THE PACKING MATERIALS

The magnet and shields are held in place with straps and lumber bracing. Disassemble the packing materials and use the lumber as dunnage. Refer to Illustration 2-9.




ILLUSTRATION 2-9REUSE THE PACKING MATERIALS

2-4-1 Rigging Crate (Part # 2298267)

Refer to Illustration 2-10, Illustration 2-11 and Illustration 2-12. The rigging crate will either ship as Crate 16 with the MINItrace system (GEMSE), or ship separately (GEMSA, GEMSAM as part number 2298267). It contains the skates, hi-jacker assemblies and accessories used to unload and move the MINItrace shield components into place. A toolbox holds the hardware you need to attach the hi-jacker assemblies. A vacuum cleaner, a ladder and dolly are also included. The rigging crate is currently packed in the same container (or truck) as the MINItrace magnet.

Recommended: Locate and unload Container 1 with Crate 16 first. Use the rigger’s tools and straps to unload the crates.

Do NOT destroy the Rigging Crate! When you finish the mechanical installation, repack the crate and return it to the corresponding service pole. Section 2-7 contains an inven-tory list and instructions to pack the rigging crate for return.

ILLUSTRATION 2-16MINITRACE MAGNET

Remember to remove the lifting yoke from the magnet before you move it indoors. For best results, unbolt the lifting yoke, and let the crane operator remove it from the mag-net and set it on the ground. When you finish, follow the instructions on <Text: Hyper-text>35 to return the lifting yoke to the factory or service pole.

Unload or move the Crates to the designated staging area. The site in the photographs had adequate space and security to store the crates outside. The installers and on-site construction workers disassembled and disposed of the crates as they were emptied. Once opened, the contents of the crates were inventoried and moved to secure storage inside the building.

Recommended: If you cannot store the crates/contents inside the building during sys-tem installation, rent a 40-ft shipping container for use as a temporary staging and stor-age facility. Most companies will provide delivery and pickup services with the rental agreement.

ILLUSTRATION 2-19MOVE THE CRATES TO THE DESIGNATED STAGING AREA

2-4-3 Unpack the Shields

The major MINItrace Shield components arrive on two Trucks/Containers. Each con-tainer holds one rear (fixed) shield and one shield door. For best results: Remove the container tops and use a crane to unload the shields. Disassemble the shipping braces and save the lumber for later use. Tell the crane operator the order in which you plan to move the shields into the building, so he or she can stage the shields to keep crane picks to a minimum.

CHAPTER 3 — POSITION THE SUBSYSTEMS

Follow the instructions in this chapter to position or mount the MINItrace components in the cyclotron room, and attach the support cabinets and cable raceway to the shield.

3-1 IntroductionNote: At this point in time, every facility design is unique. The document writers don’t

know where the architect placed the floor or wall penetrations for the product, ductwork, or power lines in your facility. We don’t know what already exists in the ceiling and wall spaces or what was added. Obtain a detailed set of site drawings, and use them in conjunction with this manual. ALWAYS defer to the site drawings. If it makes more sense to mount a panel or position subsystem in a different order than this manual suggests, by all means do so. Just remember to check each sec-tion as you complete it . Use this manual to track your progress.

3-2 Move the MINItrace Magnet into the Room

3-2-1 Introduction

Move the MINItrace magnet indoors as quickly as possible to prevent damage from exposure to the elements. For best results, consult the site drawings, and if possible, rig the magnet into the Cyclotron room to a spot directly perpendicular to its final position. Otherwise, move the magnet to a temporary indoor location, until you rig the rear shields into place. If necessary, build up the floor to the level of the epoxy area before you push the magnet aside.

3-2-1-1 Prepare the Delivery Route

The illustrations in this section show the optimal facility plan. The double doors to the cyclotron room open directly onto the temporary unloading and staging area. Most of you will not be so lucky. If you followed the MINItrace Pre-Installation manual Site Prepa-ration checklist, you should have a planned delivery route to your facility’s cyclotron room. The riggers should have walked the route to determine anchor locations for the rigging equipment, and floor protection requirements. All doorways should have been measured for minimum clearance, and doors removed, if required. The delivery route should be free from obstructions.

The following MINItrace components could damage unprotected floor surfaces:

• MINItrace magnet: 11,000Kg

• Rear shields: Left shield - 12,500Kg, Right shield - 11,00Kg

• Door shields: Left door - 8,300Kg, Right door - 7,900Kg

• RFPG Cabinet: 750Kg

• CCAB: 300Kg

Refer to Illustration 3-2. Build up surfaces to even out differences in floor levels. Use a minimum 1/4" thickness steel plate to protect the floor from damage by the heaviest components.

ILLUSTRATION 3-2PROTECT THE FLOOR FROM DAMAGE

Use the crane to move the MINItrace components as close to the facility entrance as possible. Set the magnet down on a set of rigger supplied skates, or use the hi-jacker assemblies and magnet spacers from the Rigging Crate. (See section 3-3-1 to attach hi-jackers).

CAUTION Refer to Illustration 3-5. Always wedge components on skates, to prevent unintended motion.

ILLUSTRATION 3-5USE WEDGES TO PREVENT ROLL BACK

The riggers have the responsibility to unpack and deliver the MINItrace components to their final position in the Cyclotron room. They determine how to move each piece along the route and into position. Refer to the illustrations in this section for examples and ideas.

Refer to Illustration 3-6 and Illustration 3-7. During the illustrated installation, the riggers anchored the rigging equipment to various locations on the unfinished concrete floor. They also pushed off the anchored angle iron with a house jack (Illustration 3-27). For best results ask the riggers to install the anchors and set up the rigging equipment before the system arrives on site.

ILLUSTRATION 3-6ANCHOR THE RIGGING EQUIPMENT TO THE FLOOR




ILLUSTRATION 3-7ANCHOR THE RIGGING EQUIPMENT TO THE FLOOR

The riggers may use an electric winch, mule or manual device (come-along) to pull or push the magnet along the delivery route and into the Cyclotron room. The delivery route length and complexity determines the number of times the riggers will have to insert new anchors and reposition the rigging tools. The riggers have the responsibility to supply the additional rigging equipment they need to complete the job, in addition to the contents of the Rigging Crate.

ILLUSTRATION 3-8THE RIGGER PULLS THE MAGNET INTO THE CYCLOTRON ROOM

Use straps to pull the components into position, to minimize damage to the finish.

Rigger supplied equipment




CAUTION The iron impregnated concrete shields are fairly brittle. When you wrap the rigging straps around the shields, take care to position the metal coupling devices as far away from the corners of the shields as possible. Try to posi-tion the straps so no metal comes in contact with the shield surfaces. Refer to Illustration 3-49. Use wood to protect stationary pieces from damage by the straps and cables used to pull other pieces into place.

ILLUSTRATION 3-9THE MAGNET ENTERS THE CYCLOTRON ROOM

Refer to Illustration 3-1 and Illustration 3-10. Consult the site drawings, and pull the magnet into a position perpendicular to its final installed location.

3-3-4 Caulk and Paint the Magnet Niche

If possible, finish positioning the rear shields at the end of the day, or near a scheduled break, so you can caulk and paint the inner niche before moving the magnet into the final position.

CAUTION Do NOT apply caulk to the penetrations and cable/hose raceway openings!

The system or installation gang box ships with a caulk gun and tubes of caulk.

• Before painting, apply a bead of silicon caulk to the gaps between the fixed shields and the floor.

• You may paint immediately after caulking.

The system or installation gang box ships with three 2.5 liter buckets of white paint, enough to apply two or three coats to the exposed areas of the magnet and shields.

• The paint is water-based, and dries to the touch in about 30 minutes.

• For best results, wait at least 12 hours between coats.

• To prevent injury, pad the Hinges until ready to attach the shield doors.

Follow the procedure in this section to pin the doors and complete the preliminary door adjustments. Chapter 5 contains the final door adjustment procedure. Allow the door to settle for a few days before you make the final door adjustments.

Pin the bottom hinge first. (The bottom pins are identical and interchangeable.) The bot-tom pins bear the weight of the door, and are also used to adjust the door for floor clear-ance.

1. Tighten the pin until it enters the bearing assembly.

2. Fasten the locking ring onto the hinge pin, so it isn’t lost, but don’t tighten it yet.




ILLUSTRATION 3-56PIN THE BOTTOM HINGE

After you pin the lower hinge, you can adjust the height of the hi-jackers as needed to fit the eccentric pin into the upper hinge and bearing assembly.

1. Assemble the upper hinge pins. One pin set has single scribe marks and the other has double scribe marks.

a. Slide the steel eccentric into the brass casing.

b. Align the scribe marks on the brass and steel.

c. Tighten the set screw to create a single pin assembly. (See Illustration 3-57.)

Note: The eccentric pins are NOT interchangeable. One upper door hinge has a single scribe mark and the other door hinge has double scribe marks. Make sure the marks match.

2. Insert the assembled eccentric pin through the top hinge and make sure it enters the upper bearing assembly.

• Don’t try to align the scribe marks on the pin to the mark(s) on the upper hinge until you lower the door. The object at this time is to insert the pin into the bear-ing assembly.

• Refer to Illustration 3-57. If necessary, use the wrench, included in the Installa-tion tool box, to turn the entire pin assembly until it slides into the bearing assembly.

• You can also raise or lower one or more jacks to help the pin drop into the bearing.

Locking ring




ILLUSTRATION 3-57TOP HINGE PIN

3. After the eccentric enters the bearing assembly, drop the jacks and align the scribe marks on the eccentric with the scribe marks on the upper hinge.

• Lower the jacks all the way, then raise the jack on the end opposite the hinges just enough to take the weight off of the hinges, so you can move the eccen-tric.

4. Refer to Illustration 3-58. The upper hinge has a set screw that fits into the groove that is machined around the middle of the outer brass casing.

• When the shoulder on the brass casing is flush with the top of the upper hinge, the set screw is centered in the groove.

CAUTION To prevent damage to the hinge assembly, carefully align the groove in the eccentric casing to the middle of the upper hinge before you tighten the set screw. For best results, do NOT insert the set screw into its tapped hole until the shoulder on the brass casing is flush with the top of the upper hinge.

5. Tighten the set screw in the upper hinge to fasten the eccentric into place.

6. If necessary, readjust the threads on the hinge races to align all the scribe marks.

• Recommended: Use the modified diffusion pump wrench from the hardware bag attached to the cyclotron to adjust the threads nearest the hinge. (See Illustration 5-28 on <Text: Hypertext>page 151)

7. Tighten all the nuts against the hinge races.

Set screw for eccentric

The wrench ships inthe installation tool box




8. Tighten all the pusher threads against the bearing assemblies.

• Each pusher thread should rest against its bearing assembly.

Note: During disassembly at the factory, the mechanics scribed marks on the tops of the door and fixed shield. When all the scribe marks on the hinges and pins are prop-erly aligned, the scribe marks on the doors and shields should also line up.

ILLUSTRATION 3-58UPPER HINGE SET SCREW

9. If necessary, raise the jacks to take the weight off of the bottom hinge.

10. Adjust the bottom hinge pin to raise the bottom of the shield door 3-4mm off the floor.

11. Remove the hi-jackers and move them to the second shield door.

12. Return to Section 3-5-3 and install the second shield door.

CAUTION To prevent injury or damage to the system, wedge the shield doors until the door motors have been installed.

Chapter 4 —Install the Cables, Hoses and Pipes 93

CHAPTER 4 — INSTALL THE CABLES, HOSES AND PIPES

Follow the instructions in this chapter and the designated appendices to begin the installation of the MINItrace power, signal, cooling water, gas and product lines. The shield contains many of the raceways between the cyclotron and the system support and electronics cabinets. To accommodate this integrated design, you need to pull cables, hoses and lines in a specific order. You must also reassemble and interconnect the cyclotron in stages. For best results, take the time to check for the presence of ALL connections to a cyclotron subsystem before you start to assemble it .

Note: Follow all the instructions in Chapter 4 before proceeding to Chapter 5. One person may install the cables (Section 4-1) while another person installs the hoses and pipes (Section 4-2), but each person should follow the corresponding sections from beginning to end. After you complete the tasks in Chapter 4, and proceed to Chapter 5, you may assemble the target and vacuum systems simultaneously.

When the system is disassembled for packing, the lines that run between the LTF and valve panel or Target Cooling Manifold are left attached to the LTF and the lines that run between the Target Cooling Manifold and target(s) are left attached to the TCM. Chapter 5 contains the instructions to reattach these lines to their respective units.

Your system documentation includes a customized MINItrace Pipe Work Drawing and a Cable Block Diagram. Locate and use these drawings to install the system.

• Pipe Work Drawing CAC600-17000-00-1

• Cable Block Diagram, CAC000-51003-00-3

CAUTION Read ALL the information in this chapter before you attempt to run the cables or connect the hoses, pipes and tubes. Some cables may NEVER be cut to length, while others may be cut ONLY to lengths determined by a mathe-matical formula. Each section also contains specific instructions, important information, and references to additional information in the Appendices.



94 Chapter 4 —Install the Cables, Hoses and Pipes

4-1 Run the Power and Signal Cables

4-1-1 MINItrace Cabling Information

1. Loose cables are bundled by MIS run, packed into separate boxes, and shipped in Crate 7 and 8. contains the MIS map, cable list and matrix, and the definition list of acronyms (component designators) used in the MINItrace documentation.

• The cable destinations are clearly marked on each cable.

• A basic system has 10 MIS runs, plus the RF cable.

• A system with all available options could have up to 25 MIS runs.

• Illustration 4-2 contains an example of the Cable Block Diagram, CAC000-51003-00-3. Direction 2233001 contains a larger (A3/11.5x17") drawing of the Cable Block Diagram

2. Pull the MIS run 3 Magnet Power Cables first. See Section 4-1-2.

• You may pull the remaining cable runs in any order.

3. Pull the MIS run 1a cables to the target side of the cyclotron.

• You will terminate MIS 1a cables during Chapter 5.

4. The MIS run 1b cables go to the vacuum side of the cyclotron and are already mounted in the CSC in crate 7.

• Attach the Magnet Coil Temp switch connectors to the switches shown in Illustration 4-3. (The switches are in series.)

• You will terminate the rest of the MIS run 1b cables during Chapter 5.

5. Wait until you finish the outer surfaces of the shield to install the warning lights, door sensors and door motors which comprise MIS run 2. (See Sections 5-4-6 and 5-4-7.)

6. Pull the MIS run 4 cables through the raceway on top of the shield, from the CSC to TSC.

7. IF the RF Cable has both connectors attached, you can install this cable when you pull MIS run 5. IF the cable arrives with one or both connectors missing, follow the instructions in Appendix B, Section B-3 to determine the cable length and attach the connector.

• Refer to section 4-1-3 for detailed RF cable installation instructions.

8. NEVER shorten the MIS Run 5 cable, SKA, that runs between the RFPG and the cyclotron vacuum chamber; this cable must ALWAYS be 40m long.

• You may coil and store the excess cable in the race without causing signal interference.

9. MIS run 9 cables are already mounted on the magnet in crate 6.




10. Start the run from the Electronics or Support cabinet end first, and terminate the cables at the cyclotron last.

11. Keep power cables away from the signal cables in the raceways. The raceways are wide enough to provide space for separated power cables, signal cables, hoses, pipes and air lines. Keep runs neat and use plenty of ty-wraps.

• You may coil, ty-wrap and store the excess lengths of cable in the raceway.

12. PAY ATTENTION to the labels on the cables. Most signal cables have a male and female end. Make sure you orient the cables correctly when you run them.

• The cable label describes the termination point. (ex: The end labeled CCAB GCU P3 terminates at connector P3 of the General Control Unit in the CCAB.)

13. For best results, check off each cable in the cable list as you install it .

• When you finish a bundle, color the corresponding run on the MIS Map, Cable Block Diagram and/or Site plans.

14. The Cyclotron Support Cabinet (CSC) arrives with the cables already attached to the components in the Vacuum Cooling and Control panel.

• Remove the loose cable ends from the CSC and run them into the raceway.

• Use the Basic Cable Block Diagram (CAC000-51003-00-3) to locate the desti-nations when you run these cables.

15. The cyclotron has conduits and raceways integrated into and beneath the shield. These penetrations accommodate all the cables, hoses, pipes and tubes.

• The cyclotron cooling hoses exit the bottom of the CSC and run beneath the fixed shield, and into the cavity with the magnet. (See Illustration 4-15.)

• The power and signal cables exit the shielded raceway through the hole in the top of the fixed shield, pass through an integrated conduit, and into a raceway attached to the inner niche wall of the right fixed shield. (See Illustration 4-1 and Illustration 4-4.)

ILLUSTRATION 4-5COILED CABLE

• IF you must attach one or both connectors, follow the instructions in Appendix B.

Notice If you have to attach a connector to one end of the cable, first measure and cut the cable to length, then push the raw cable end through the corrugated conduit in the shield before attaching the connector. Don’t fasten the other end to the RFPG cabinet until after you attach the connector, so you can pull enough cable through the conduit to work comfort-ably. Attach the connector to the cable, push the excess cable back through the shield conduit, then fasten the ends of the cable to the magnet and RFPG cabinet.

Magnet cable contact plate

Ground stud

Sharper bends than this become permanent.




1. IF the cable arrives with both connectors attached, one end should have about 50mm of the outer insulation removed near one of the connectors, exposing the outer copper conductor.

• Orient the cable with the exposed conductor at the RFPG cabinet.

• If necessary, refer to the instructions on page 285 in Appendix B to cut away the insulation to expose the copper conductor.

2. Run the RF Cable outside the shielded raceway.

• Consult with the contractor before supporting the cable or fastening it in place. Local building codes may prohibit fastening cable supports to existing compo-nents in the ceiling space.

• If necessary, ask the contractor to shoot some wires into the ceiling, and use them to support the cable over the suspended ceiling.

3. You may not make a single bend in the cable with a radius of less than 180mm or multiple bends with less than 550mm radii.

• Refer to Illustration 4-5. If you make any bends with a smaller radius than these loops, the bend becomes permanent. Plan every bend carefully.

• If you must negotiate a very tight bend, and no alternative routes exist, con-tact the Uppsala factory for additional connector hardware and instructions.

4. Refer to Illustration 4-6. Remove the outer connector retaining ring and C-rings from the cyclotron end of the RF cable.

• The connector retaining ring is held in place by internal C-rings.

• Use a small hammer to tap the retaining ring downward, until it slides down the body of the RF cable connector.

• Remove both C-rings from the connector.

• Remove the retaining ring from the connector.

• Wrap a piece of plastic or bubble wrap around the end of the cable before you insert it into the shield conduit.

5. Start at the RFPG cabinet, and feed the cable above any suspended ceiling, toward the cyclotron.

• If you have to attach a connector to the cable, push the raw end through the conduit in the shield first. (See the note at the beginning of this procedure.)

4-2 Hose and Pipe Information Every system has a unique Pipe Work Drawing, similar to Illustration 4-10. The labels on the drawing match the labels on the finished hoses. Labels for the lines you cut to length also come with the system, and should be attached after you install the tube. (Some penetrations are too small to accommodate the tubes with their labels.) The Pipe Work drawing also contains a key that describes the types and sizes of tube to use for each run. Lines run between the Cyclotron room and the Radiochemistry lab. The remainder run between the support cabinets and cyclotron subsystems.

• Appendix B contains instructions to make the Swagelok and RF Cable connections.

For best results:

1. Hang a copy of your site’s Pipe Work Drawing in the Cyclotron room.

2. Choose a line to run.

• Pay attention to the number of lines listed for each run on the Pipe Work draw-ing. You should run eight spares for every tefzel product delivery line.

• When you run the spares, remember to use permanent markers to mark both ends of each line with the same unique identifier, so the person changing lines over the coming years can make the correct connections on the first try.

3. Refer to the key, and choose the correct hose, pipe or tube material.

4. The following tables list the connections by destination, or size and type.

• Cyclotron Supply Panel: Table 4-1 on page 109

• 3/8" Rubber Hose (RH): Table 4-2 on page 112

• Rubber hoses from CSC to Electronics Cabinets: Table 4-3 on page 113

• 4mm Polyurethane (Pu): Table 4-4 on page 116

• 1/16" Tefzel: Table 4-5 on page 117

• 1/8" Stainless Steel (SS):Table 4-6 on page 121

• 3/8" Polyurethane (Pu): Table 5-2 on page 138

• 3.18mm Polyurethane (Pu): Section 5-2-6 on page 140

• 1/16" PEEK: Table 5-3 on page 148

5. Crimp the end of the metal pipe shut, or tape the end of the polyurethane or tefzel tubing, to prevent any debris from entering it while you push/pull it to its destina-tion.

6. Feed the pipe/tube through the penetration, to its destination.




Note: At least one penetration between the cyclotron room and radiochemistry lab should have a piece of PVC conduit with shallow bends installed in it , to accommo-date the tefzel lines that deliver the product to the lab. These lines must be replaced on a regular basis, and the conduit helps ease the way. Run all active and spare tefzel lines through the conduit. Remember to mark the spares.

7. Remove the tape or cut off the crimp, restore the roundness of the open end, and attach it to the corresponding tube fitting.

8. Attach the label to the pipe or tube with two ty-wraps.

9. Cut the pipe to length, fasten the other end to its fitting, and attach the label.

10. Color the corresponding line on the Pipe Work drawing.

• In theory, when you run out of labels, the gas/product pipe work is finished. However, compressed air lines currently do NOT have labels.




ILLUSTRATION 4-10EXAMPLE OF PIPE WORK DRAWING




4-3 Attach the HosesThe hoses that run between the CSC and the cyclotron have been cut to length, fitted and labeled. The hoses that run from the CSP to the CSC, and on to the RFPG and CCAB may have to be trimmed to length.

The fittings are already attached to the support panels, cabinets and magnet. The hose clamps are attached to the corresponding panels, along with the mounting hardware. (The installation gang box should also have spares.) The fitted hoses use Swagelok con-nectors. Use a wrench to attach the fitted hoses to the system connectors. Appendix B contains information about Swagelok connectors. If you have to manufacture or refit one of the hoses, first read the information in Section B-1.

The following tables contain piping connections for a dual extraction MINItrace system. If your system has additional options, you will have additional tubes and pipes to install. Every installation has its own Pipe Work drawing, which shows the system connections. Use this drawing to ensure all connections have been made on your system. For best results, color or highlight each line on the drawing as you install it.




ILLUSTRATION 4-11THE CSP LINKS CUSTOMER SUPPLIED LINES TO THE MINITRACE SYSTEM

4-3-1 Attach the Cyclotron Supply Panel Hoses

On most sites, plumbers and fitters install the water and air lines and make the connec-tions between the air compressor, the chiller and the CSP. The installation team makes the connections between the Cyclotron Supply Panel and Cyclotron Support Cabinet, and from there to the MINItrace subsystems.

To attach an unfitted hose:

1. The hoses that run between the wall-mounted Cyclotron Supply Panel and the Cyclotron Support Cabinet (CSC) need to be cut to length from the raw hose sent with the system.

a. Cut the end of the hose evenly, so it butts snugly against the top of the fitting.

b. Slide a hose clamp onto the hose, then slide the hose onto the fitting.

Notes and Comments:



Chapter 5 —Assemble the Cyclotron 127

CHAPTER 5 — ASSEMBLE THE CYCLOTRON

Follow the instructions in this chapter to complete the assembly and installation of the MINItrace cyclotron and support systems. This chapter also contains the instructions to repair and finish the shields. When you complete all the Chapter 5 procedures, the sys-tem is ready for power checks and start-up.

Note: Follow all the instructions in Chapter 4 before proceeding to Chapter 5 . After you complete the Chapter 4 tasks and prep the interior shield, two people may assem-ble the target and vacuum sides of the cyclotron simultaneously.

5-1 IntroductionThe MINItrace shields house the cyclotron and part of the target and vacuum support systems. The cabinets attached to the right and left fixed shields house additional cyclo-tron and target support systems. Any component that has the potential to become radioactive, either during normal use or catastrophic failure, is housed inside the shields.

Before you start to reassemble the cyclotron:

• Verify all cables and hoses from the CSC have been pulled into the interior niche. (Wait until you install the Target Cooling Manifold and Valve panel to pull the lines from the Liquid Target Filler and Helium Compressor in the TSC.)

• Repair any shipment damage to the interior surfaces. (Follow the application direc-tions on the can of plastic filler.)

• Paint the inner and outer shield surfaces (Continue to periodically paint and touch up the surfaces until satisfied with the finish.)

Notice Any time you paint the shields, cover any exposed components, cables or hoses with plas-tic. Wipe up or smooth out any drips as soon as you discover them. When you make the final door adjustments, the tolerances are so small that a dried paint drip can prevent the doors from closing. When you repair the damaged areas, sand the surfaces completely smooth before you paint them. Too much plastic filler (bond-o) will also cause problems during the final door adjustments.

5-4 Finish the Cyclotron Installation

5-4-1 Final Door Adjustments

If you followed the directions in section 3-5-5 of Chapter 3, the doors should be fairly well adjusted, and should have had time to settle while you installed the cables and hoses.

1. Remove the wedges from the doors.

2. Push and pull on each door and watch its motion.

• Ideally, the door should stop when you stop applying pressure.

• If the door tends to drift , it should drift TOWARD the fixed shield, NOT away from the fixed shield.

• If the door drifts, it should NOT gain momentum as it moves; it should NOT slam into the fixed shield.

• The door should NOT make contact with the cyclotron.

• The door should rest against the fixed shield without striking it, leaving a 1 or 2mm gap between the inner surface of the door and the fixed shield.

3. If the door fails to meet the Step 2 criteria, adjust the bearing assembly.

• Recommended: Use the modified diffusion pump wrench to adjust the threads nearest the hinge. (See Illustration 5-28 on page 151.)

4. Refer to Illustration 5-34. Attach the Lift Plate to the end of the door opposite the hinges, and use the remote jack to take the weight off the hinges.

ILLUSTRATION 5-34LIFT PLATE AND REMOTE JACK

• To pull the door away from the fixed shields: Loosen the nuts and adjust the threads

• To push the door toward the shield: Adjust the threads without the nuts,.

Note: If you become "lost or confused" adjust the pusher and puller threads to align the scribe marks on the top and bottom hinge and bearing assemblies, and start again.

If necessary, use pieces of steel plate to raise the remote jack into position.




5. Release the remote jack and try the door again.

6. When satisfied with the door motion, adjust the eccentric to fit the door to the shield.

• Take the weight off the hinges, and align the scribe marks on the eccentric to the mark(s) on the hinge race

• If necessary, continue to adjust the eccentric until the door fits evenly against the shield, leaving about a 1 or 2mm gap between the two surfaces.

7. After you fine tune both doors, try closing them together.

• Make sure the two doors DO NOT collide.

• When closed, the door surfaces should be flush, with a 1 or 2mm gap between them.

Right and Left Shield Doors adjusted.

5-4-2 Install Right and Left Cosmetic Covers

The Cosmetic covers consist of two metal brackets and a vinyl cover. The brackets fas-ten to the shield and support cabinets to cover the hinge.

Note: Remove the CSC door to install the right cosmetic cover. Remove the three cotter pins that fasten the CSC door to its hinges.

1. The right and left cosmetic covers and hardware ship in Crate 7.

2. Tightly fasten the M8 all-thread (guide pin) to the tapped holes in the shield doors.

3. Fasten the cosmetic cover to the shield door with M8 hardware. (flat washer and nut)

• If the cover doesn’t fit , build up the guide pins with one or two washers.

5-4-4 Final Cleanup and Repair of Damage

The shields will suffer damage during shipment in the containers. Purchase cleaning supplies locally. The system ships with a box of damage repair and paint supplies. Also check the gang box for additional tools and supplies.

1. Clean all surface dirt and debris from the interior and exterior shield and cyclotron.

2. Follow the instructions on the can of "Plastic Padding" ("bond-o") to mix the two-part compound and fill in any scrapes, divots and chips.

• If the damage is deep, you may have to apply multiple coats over a period of days.

3. After the plastic filler dries, sand it smooth.

5-4-5 Final Touch-up of Outer Shield Surfaces

Sand any rough spots or dried paint drips. Check all surfaces and fill any remaining nicks or scratches. Apply the final coat of paint to the inner and outer shield surfaces.

1. The system or gang box ships with three 2.5 liter buckets of white paint, enough to apply two or three coats to the exposed areas of the magnet and shields.

• The paint is water-based, and dries to the touch in about 30 minutes. For best results prop the doors open, and wait at least 12 hours between coats. Apply the final coat at least a day before you attach the labels.

2. After the final coat dries, open and close the shield doors to make sure they still fit correctly, and don’t make contact with the cyclotron when you close them.

3. Check the gap between the doors. The door surfaces should remain flush.

5-4-6 Install Warning Lights and Door Sensors

The warning light and door sensors are attached to a single mounting plate and ship with the cables in Crate 7, with the cables already attached. The metal blocks that mount on the shield doors ship with the warning light assembly.

Chapter 6 —System Phase and Power Checks 167

CHAPTER 6 — SYSTEM PHASE AND POWER CHECKS

Follow the instructions in this chapter to check the phase of the power into and out of the Mains Distribution Panel and PDU, as well as the phasing and power inputs to the subsystems.

CAUTION The MINItrace subsystem has two phase sensitive components, the Rotary pump and the SWCU pump. If you apply power and run the pump and motor with the phases swapped, you will damage or destroy them. NEVER apply power to a MINItrace subsystem until you are sure the input power and phasing has been verified. If necessary, ohm out the wiring to the subsystem in question, and correct any cabling errors before you apply power to the component.

6-1 Input PowerThe RFPG and CCAB can accept input voltages of 208VAC, 400VAC or 480VAC. The MINI-trace Service Manual has a Generic Mains Distribution Drawing, CAA209-56001-xx-2, which currently applies to all three input voltages.

Measure the power into the Mains Distribution Panel (MDP) to determine which voltage this site uses.

In addition to the MDP circuit breakers, the customer provides one standard power out-let for the MASTER and one for the optional FDG mini lab, if present.

6-2 MASTER Power ChecksStandard power outlet for MASTER present?

Check the outlet voltage. Does it match the value on the drawing?



168 Chapter 6 —System Phase and Power Checks

6-3 Mains Distribution Panel (MDP) Power ChecksCheck that the power rating for the RFPG and CCAB circuit breakers are at least 20kVA.

1. Turn OFF all circuit breakers in the back of the CCAB and in the CSC.

2. Open the lower front cover on the RFPG and turn off SW1.

3. Use an oscilloscope or phase sequence analyzer to check the L1, L2,L3 voltage and the phase relationships of the incoming power to the MDP.

• If necessary, correct any cabling errors at the source.

4. Record the voltages in Table 6-1 .

• The MDP has 4 circuit breakers for the standard MINItrace system.

c. When the screen prompts you to switch off power, you can safely turn off the workstation.




16. If construction work is still going on, unplug the workstation and cover it, the key-board and printer with a dropcloth or a sheet of plastic to keep out the dust. (Or turn the workstation boxes into covers.)

Control system Start-up successfully completed.




7-3 Water Cooling SystemFollow this procedure to bleed all the air from the water lines, and check for leaky con-nections. Keep a bucket and mop and/or sponge nearby! Chapter 8 of the MINItrace Service Manual (Dir# 2233000) contains more detailed information about the Secondary Water Cooling System.

Note: You may fill and bleed the lines as soon as you finish making all the cooling water connections, before applying power to the system. If the compressed air is not yet available, you may be able to fill the and bleed the lines just using the incoming water pressure. When you bleed the target system, things will change, so it’s your option to wait until the targets are in place, then fill and bleed all eight circuits in one session.

7-3-1 Fill the Secondary Water Cooling System with Water

Note: The system specifications call for the installation of two bleeder valves at the high-est point in the chiller lines. The valves should be auto bleeders. Check with the contractor for the actual location(s) and types of valves used on at the facility. If you experience problems with the incoming water, you may have to check these valves.

Repeat the following procedure on each cooling water circuit. Do NOT fill the Target cooling circuit until the Targets have been installed. Start with the RFPG circuit and work your way from left to right, skipping the target circuit , if necessary.

1. Check and tighten ALL the hose connections before you fill the circuit with water.

• Tighten ALL the hose connections on the pressure side of the manifold. (upper tier)

2. Refer to Illustration 7-1. Check the view port on each flow meter in the lower tier (return side) to make sure you have a clear view of the interior. Sometimes the inner sleeve shifts during shipment. If this happens:

a. Loosen the four hex cap set screws at the top of the meter and remove the cap.

b. Insert your finger into the meter and turn the inner sleeve until you can see the indicator cone, the black rod and the back of the meter.

7-3-2 Start up the Secondary Water Cooling System

Follow the instructions in this section to start pumping water through the secondary water cooling system.

Note: The MINItrace is staged with a 50Hz water pump. If the system goes to a facility with 60Hz power frequency, the pump is changed during the disassembly and packing process. IF your site has 60Hz power, it is very important to make sure the 60Hz pump is present and rotating in the proper direction when you apply power.

1. Check that the primary cooling water temperature falls between 10 and 13oC.

• If the water temperature falls at the low end of the range, check the hoses for condensation and make sure the pipes to the shunt are well insulated.

• If the water temperature falls at the high end of the range, you may have to increase the water flow through the system to provide adequate cooling.

2. Check the secondary cooling water temperature on the panel beneath the VCU.

• The water temperature should remain steady at 20oC +/- 2 degrees.

3. Refer to Illustration 7-5. Locate the water pump beneath the return valves in the CSC.

• Make sure the round frequency sticker on the side cover of the pump matches the on-site power frequency.

• If a mismatch exists, DO NOT apply power until you replace the cooling pump.




ILLUSTRATION 7-5SECONDARY COOLING WATER PUMP

CAUTION Do NOT start the water pump until you bleed out any air that may be inside. Failure to bleed the pump before starting it could damage the pump vanes.

4. Bleed the water pump before you start it:

a. If necessary, adjust V50 until the water pressure at BP1 falls between 0.5 and 0.75bar.

b. Refer to Illustration 7-2. Place a bucket against the water pump bleeder, to catch any water.

c. Refer to Illustration 7-2. Open the bleeder on the water pump, and let the pres-sure in the system drive out the air.

d. Close the bleeder valve when only water escapes.

5. Check the pump phasing.

a. Locate the yellow rotational direction sticker on top of the pump.

b. Locate the CP circuit breaker (CB2) and contactor (CON2) in the narrow CSC.

c. Turn on CB2.

d. Briefly turn on and off the VCU Cooling ON button on the control panel as you check the direction of the fan blades. Look through the ventilation-grating on the top of the water pump. Use a flashlight for a better view.

e. If the direction is wrong; turn off the pump and CB2. Locate the source of the phase swap.

6. If the phasing is correct, start the water pump and bleed it

a. Press the VCU Cooling ON button, on the control panel, to start the pump.

b. Run the pump for three seconds.

c. Refer to Illustration 7-2. Stop the pump, open the bleeder, and bleed out the air.

d. Run the pump for six seconds.

e. Refer to Illustration 7-2. Stop the pump, open the bleeder, and bleed out the air.

f. Run the pump for 12 seconds.

g. Refer to Illustration 7-2. Stop the pump, open the bleeder, and bleed out the air.

h. Continue to start the pump for 12 seconds, stop it, and open the bleeder, until NO air escapes.

i. When only water escapes from the bleeder, turn on the pump for two minutes, then stop the pump and bleed it .

j. When NO air escapes after running for two minutes, you have successfully evacuated all the air from the cooling system.

7. After you finish bleeding the air from the system, leave the pump on, and start to open the cooling circuits.

a. Check the water wheel, F10, above the pump for motion. Adjust V51 until you can see the blades rotate. (If the wheel looks like a blur, the flow is too fast.)

b. Check the internal CSC components and hoses for water leaks under pressure.

8. Open one set of pressure and return valves and check the corresponding hose con-nections for leaks.

• Continue to open each (completed) circuit in turn, while monitoring all active circuits.

• Periodically check the hose connections on the active circuits every day, for leaks.

9. When you open a cooling circuit, turn the return (lower) valve fully clockwise.

10. Refer to Table 7-2 . Adjust the water flow meters in the individual circuits with the corresponding pressure valves.

• If the water flow falls below an acceptable level, the MSS will display an alarm.




TABLE 7-2FLOW METER SETTINGS

11. During normal system operation, the watch tube should remain about half filled and BP1 should read about 0.5bar. Refer to Illustration 7-3, Illustration 7-4, and Illustration 7-6.

a. Adjust BP1 to 0.5mbar by changing the pressure in the C1 tank.

1. Locate the EXP (expansion) valve on the C1 block.

2. If the BP1 pressure is too high: Push the blue sleeve against the C1 block to release the pressure on the hose. Open V53 to release pressure in the C1 tank until BP1 drops to 0.5mbar.

3. If the BP1 pressure is too low: Pull the blue sleeve away from the C1 block to pressurize the hose. Open V53 to increase pressure in the C1 tank.

b. Adjust the watch tube level with V50 and V80.

1. If the watch tube level is too low: Adjust V50 until the water rises about half-way up the watch tube.

2. If the watch tube level is too high: Locate the open end of the hose attached to V80 and place it in a bucket. Adjust V80 to drain the excess water from the watch tube.

12. Continue to monitor the secondary cooling water temperature on the panel

beneath the VCU. It should remain steady at 20oC +/- 2 degrees, with no condensa-tion on the lines.

Tip: Refer to Illustration 7-6. If you need compressed air, attach the hose to one of the unused valves on the back of the C1 block. Slide the blue sleeve away from the C1 block to turn on the compressed air.

7-8 Helium Cooling, LTF, and Target Support System Checks

7-8-1 Introduction

Most of the target support lines from the LTF and Target Cooling Manifold (TCM) are cur-rently unmarked. Follow the procedures in this section to make sure the Targets and corresponding support systems are correctly installed and leak free.

This manual assumes the target options are connected to the following ports:

• Target 1: 18F- Option; Single and Dual Extraction (page 226)

• Target 2: 11C Option (Refer to the MINItrace Maintenance Manual for detailed installation instructions.)

• Target 3: 15O Option (Refer to the MINItrace Maintenance Manual for detailed installation instructions.)

• Target 4: 13N Option (page 230)

• Target 5: Dummy (Proton) Target [All Systems]

• Target 6: 18F- Option; Dual Extraction only (page 226)

Your system may differ from this configuration. If so, select the target position that cor-responds to the location of the target on your system. If unsure of the target configura-tion on your system, check the configuration files on the system MASTER. 7-2 contains the instructions to check the configuration files.

Notice If the MASTER and MSS have different configuration file contents, the system won’t start. If you change the physical target port location, remember to update the MASTER configu-ration files by saving the MSS configuration to the GSU.

When you complete the corresponding step.

1. Make sure all the targets have been installed in the correct ports, and that all cur-rent sensing, cooling and product lines are securely attached.

2. Check all the physical connections. Make sure all the hoses, pipes and tubes have been correctly installed and securely fastened.

• Make sure the helium and water lines to the targets are correctly oriented. The brown gas line has a green stripe, and always attaches to the upper connector. The brown water line has an orange stripe, and always attaches to the bottom connector. Both lines have the same outside diameter (1/16") but different interior diameters.

3. If you didn’t fill and bleed the target cooling lines when you started the Secondary Water Cooling Unit, return to 7-3 and fill the target cooling circuit.

4. Press the VCU Cooling panel ON button to start the SWCU pump.

5. Make sure all the gas bottles are in place and connected.




6. If necessary, turn on the gases and adjust the regulators.

• Appendix D contains the list of purity and pressures settings for the system gases.

7-8-2 F18- Option: Single and Dual Extraction systems

CAUTION If you are color blind in the red/green spectrum, carefully check the connec-tions, then mark or label the lines to prevent future problems. Recom-mended: Use a permanent marker to make series of rings around the gas line(s).

7-8-2-1 Check the Helium Cooling System

Display the Target handling screen on the MSS.

a. Display the MAIN MENU.

b. Click on the first target icon to open the 18F- Target menu page.

7. Click CONNECT TARGET.

8. Click SELECT TARGET to open the water valve (7) and start the Helium cooling com-pressor(s).

• The water flow indicator in the water cooling window changes from yellow to green.(If not, the entire process shuts down with error messages.)

• The He-cooling indicator turns ON.

• The He-cooling valves open and close as the He cooling system empties and fills.

• The Pressure increases to 18psi and the compressor continues to run.

9. Once the Pressure reaches 18psi, continue to monitor the system for 5 minutes.

• Make sure the system maintains pressure for five minutes without any error messages, alarms, or additional messages that it is filling the system with He.

• If the system cannot maintain pressure, or refills the system every minute or two, start looking for leaks.

10. After five minutes, click UNSELECT TARGET.

• The compressor should stop running.

Note: If you plan to operate the He compressor manually, click EMPTY before you click ON. You must empty the system before you can start it .




7-8-2-2 Check the Gas Connections to the F18- Target

Make sure the gas line is brown with a green stripe, and is attached to the upper con-nector. The water line is brown with an orange stripe, and always attaches to the bottom connector. Both lines have the same outside diameter (1/16") but different interior diam-eters.

1. Physically disconnect the gas line from the upper connector on the target.

2. Click on the 1a valve to open the low pressure helium line to the target.

3. Place your finger over the end of the tube and check for the flow of gas.

4. Click on the 1a valve to close it .

5. Check that the gas stops flowing from the tube.

6. Click on the 1b valve to open the high pressure helium line to the target.

7. Place your finger over the end of the tube and check that the flow of gas is much stronger than before.

8. Click on the 1b valve to close it and stop the flow of gas from the line.

9. Reattach the brown and green line to the upper connector.

10. Click on the 1b valve to open the high pressure line to the target, and check that it takes less than one minute for the pressure to reach 300 to 320psi.

• IF the pressure exceeds 320psi, or it takes longer than one minute to reach pressure, adjust the regulator on the customer side of the gas manifold.

• IF you cannot reach pressure by adjusting the customer regulator, the line could be blocked. Locate the needle valve directly behind the P1 connector to the LTF. Back off one turn on the knurled silver knob for a few seconds, then retighten the knob one turn.

11. Click on the 2b outlet valve to release the target pressure.

12. Repressurize the target.

13. When the target pressure reaches 300 to 320psi, click on the 1b valve to close it .

14. Monitor the level for at least two minutes to make sure it doesn’t drop.

• IF the target pressure falls below 300psi during the two minute time period, tighten all the high pressure PEEK connections, and try again. If necessary, fill a spray bottle with soapy water, set it to the "mist" position and use it to check the system for leaks. You may also use SNOOP (available from plumbing supply stores) or the helium detector that ships with the MINItrace, to find any leaks.

15. Dual Extraction systems: Select Target 6 and repeat Step 1 through Step 14.

16. Check the product line connections to the hot lab:

a. Click on the 1a valve to open the low pressure helium line to the target.

b. Click on the 2a and 2b outlet valves to open the line to the hot lab.




c. Check the outlet line in the hot lab to make sure gas is flowing from the tube.

d. Repeat the process on each active outlet line.

7-8-3 Check the F18- Target Water and Product Line Connections

The water line is brown with an orange stripe, and always attaches to the bottom con-

nector. A single line supplies both the 16O and 18O water to the 18F- target.

Notice Make sure you use the sterile, deionized 16O water during these tests. Do NOT use the

extremely expensive 18O water until specifically told to do so during the functional testing

phase of the start-up process. Use only 16O water to test the timing and connections of both LTF syringes.

1. Fill the 16O vial on the LTF with water, and insert a needle into the vial.

2. Move the MSS near the TSC.

3. Leave the valves in their current state, so the water doesn’t leave the LTF.

4. Click on the syringe icon on the MSS and watch the syringe fill in the LTF.

• The syringe should take about 10 seconds to fill.

5. Click on the syringe icon on the MSS and watch the syringe empty in the LTF.

• The syringe should take about 4 seconds to empty.

6. Continue to click on the syringe icon to fill and empty the LTF syringe while you check the timing.

• Too fast: The increased pressure could pop the needle out of the water vial.

• Too slow: The pump may not fill correctly; insufficient water to the target.

Note: The fill and empty times were set at the factory, and should be fine. If you need to adjust the fill or empty times, locate the screws at the top and bottom of the syringe body. Adjust the bottom screw to change the syringe speed and fill time. Adjust the upper screw to change the time to empty the syringe.

7. Remove the bottom (brown/orange) line from the target connector, and put it in a bottle, to catch the water.

8. Click on the syringe icon to fill the LTF syringe.

9. Click on valve 3 to open it . (Click on valve 4 when you test the 18O connections.)

10. Click on the syringe icon to empty the syringe.

• Check that a steady stream of water flows from the tube.

11. Reattach the water line to the bottom connector on the target.




12. Fill the target with sterile water.

• Click on FILL WITH H216O.

-or-

• Click on FILL WITH H218O when you test the 18O connections.

13. Make sure the pressure reading on the MSS rises as the target fills with water.

14. Check the target connections for leaks.

15. Locate the bundle of tefzel lines (active line and spares) in the hot lab.

16. Place the active tefzel line(s) into a vial or bottle, to catch the water.

17. Click on EMPTY TO OUTLET 1.

• Make sure the water exits the correct line.

• Measure the water and compare the amount to the one recorded in the data sheets that arrived with the system. The two amounts should be the same.

18. Refill the target with sterile water.

• Click on FILL WITH H216O.

-or-

• Click on FILL WITH H218O when you test the 18O connections.

7-9 Beam TuningFollow the procedures in this section to condition the system and tune the beam, to pre-pare the system for functional testing. This section assumes the Secondary Cooling Water, Vacuum, Magnet, and RF System start up procedures were successfully com-pleted.

7-9-1 Condition the System

Note: Return to this section any time you open the chamber. If you make a physical adjustment to the Ion Source or do anything to the interior of the vacuum chamber that exposes new metal, expect a significant increase in conditioning time.

1. If necessary:

a. Press the VCU Cooling panel ON button to start the cooling water pump.

b. Press PUMP at the VCU to pump down the chamber to the standby state.

2. Connect the Service PC (MSS) to the port on in the narrow CSC.

3. Display the BEAM CONTROL page.

4. Click GAS ON to clear the pipe to the Ion Source (IS).

5. The Vacuum chamber pressure will increase from the -7 range, to 1.5 to 2.5 x 10-5 when you turn on the gas.

• Let the chamber pump down with the gas on for at least 30 minutes.

6. After 30 minutes, click GAS OFF so you can change MSS pages.

7. Display the MAGNET SYSTEM page.

8. Click the magnet ON button.

9. Set the magnet current to the value listed on the factory data sheets.

10. Display the RF SYSTEM page.

11. Type/enter a Set Frequency value of 80%.

12. Click SAVE FREQUENCY to set the upper range limit for the frequency sweep.

13. Type/enter a Dee Voltage value of 25kV, which equals 50% of full power.

14. Click STANDBY.

• The system should take about one minute to transition from the STANDBY to the READY state.

15. When the STANDBY indicator changes to READY, click NORMAL.

• During the conditioning process, the Dee Voltage status changes from START MODE, to SPARKS and TUNING MODE as the system sets up the scanning fre-quency and Dee voltage.




16. When the Dee Voltage status changes to a steady DEE VOLTS OK for 3 minutes, click on the UP arrow to increase the Dee Voltage.

• IF you don’t see a DEE VOLTS OK after 5 minutes, drop the Dee Voltage to 15kV, and restart the conditioning process.

17. Continue to increase the Dee Voltage, until the system reaches a steady DEE VOLTS OK for 5 minutes at 35kV (normal operating voltage).

18. During the Beam Tuning process, return to this section anytime you introduce a new variable that causes the system to spark.

• Drop the Dee Voltage to 25kV until the status changes to a steady DEE VOLTS OK, then increase the Dee Voltage back to 35kV. If the system doesn’t reach DEE VOLTS OK at 25kV, drop down to 15kV, and start from there.

7-9-2 Tune the Beam

Once the Dee Voltage status reaches a steady DEE VOLTS OK at the 35kV setting, you can start to tune the beam. Whenever the system starts to spark, return to the condi-tioning process. Dual Extraction systems tend to be more non linear than Single Extrac-tion systems until the IS current reaches 200mA.


2. Click RF NORMAL to set the Dee Voltage to the value in the configuration file.

• The RF SYSTEM values displayed on this page are more of a mean, and not as "realtime" as the values on the RF SYSTEM page.

3. When the status changes to a steady DEE VOLTS OK, click GAS ON.

• The system will start to spark and retune the frequency. Allow the system to remain in this condition until it starts to stabilize.

4. When the status changes to a steady DEE VOLTS OK, click PROBE IN.

• The Flip-in Probe protects the target from the beam.

5. Click IS ON.

6. Type/enter a Current Set value of 10mA.

• Even though the field may display a value when you click IS ON, it’s probably the last typed value, which the system ignores, so you have to type in a new value.

• IF the system starts to spark when you enter the 10mA value, change the Cur-rent Set value to 0mA, and return to the conditioning process in section 7-9-1.

Note: When you set a new IS current, the IS Voltage should increase to about 900v, then slowly decrease as the actual IS Current value increases to the Set value. IF the ION SOURCE voltage goes above 1kV, check the cable connection to the Ion Source. (Especially if you have taken the IS assembly out of the vacuum chamber.) The coax cable has an extra long sleeve, which can deceive you into thinking it’s connected when it really isn’t .




7. If the Dee Voltage is OK, and the current reading on the Flip-In Probe equals 1µA, wait one to two minutes, then increase the ION SOURCE Current Set value to the each of the following values for at least two minutes.

Note: If the system starts to spark, enter a value of 0mA, and return to the conditioning process.

When changing from a lower to higher current, or lowering the current to a non zero value, the system ramps up/down. When you set the current to zero, it goes immediately to zero.

• 20mA should produce a Flip-In Probe current of 2µA ±20%









Note: IF you don’t see a Probe current of 100µA ± 15% on the probe at 1000mA IS cur-rent, then it’s time to check the Dee adjustments and the position of the Ion Source slit . Follow the maintenance and service instructions in Direction 2233000.




7-10 Target System Start-upFollow the procedure in this section to check and adjust the collimators to center the beam on the corresponding target. If you added a target option during the installation, and had to install the target collimator, follow the procedure in Section 7-10-2, page 241, before you start this section.

WARNING RADIATION! ALWAYS MEASURE THE ACTIVITY WHEN YOU OPEN THE VACUUM CHAMBER DOOR, SO YOU KNOW HOW LONG YOU CAN STAY IN THE CHAMBER AREA. REMEMBER: DOSAGE LEVEL LIMITS VARY FROM COUNTRY TO COUNTRY.

• If necessary, return to section 7-9-1 and condition the system.

16. Click on Ion Source GAS ON.

• Make sure the RF SYSTEM window still displays dee volt , ok.

17. Select ION SOURCE (IS ON).

18. Set the Ion source to 100 mAmp, and wait for Dee volts to stabilize.

19. Adjust ion source current to produce about 4microamps on the probe, because the paper burner does NOT have cooling water lines.

20. Make paper targets out of business cards while waiting for the Dee volts to stabi-lize:

a. Cut a business card in half, width-wise.

b. Measure from the lower right corner of the card.

c. Draw a horizontal line 19.5mm above the bottom edge of the card.

d. Draw a vertical line 19.5mm from the right edge of the card.

37. Type the upper collimator value, then type the lower collimator value into the field 3 or 4 times for each value, to sweep the beam back and forth between the collima-tors.

Note: You may need to experiment with the number of times you enter the values. The number of times needed to sweep the beam across the collimator blades will increase as the paper thickness increases. Try not to over burn (blacken) the paper. It is better to under burn than over burn the paper target.


39. Click on IS OFF.

WARNING RADIATION! WEAR GLOVES AND PROTECTIVE EYEWEAR WHEN YOU OPEN THE TARGET SHIELD DOOR AND REMOVE THE PAPER. ALWAYS MEASURE THE ACTIVITY WHEN YOU OPEN THE SHIELD DOOR.

40. Use forceps to remove the paper from the Paper Burner Target.

41. Refer to Illustration 7-27. Examine the burn mark.

• The burn mark on a liquid target should be centered horizontally, but slightly lower than center on the vertical axis.

• The burn mark on a gas target should be centered directly over the crosshair.

WARNING RADIATION! THE PAPER IS RADIOACTIVE (CARBON ISOTOPE). DO NOT TOUCH THE PAPER WITH BARE HANDS. STORE THE PAPERS IN A LEAD CONTAINER FOR AT LEAST 2 HOURS. IF POSSIBLE LEAVE THE PAPER IN THE CONTAINER OVER NIGHT.




ILLUSTRATION 7-27PAPER TARGET FOR LIQUID TARGET

42. Repeat the test two or three more times at the current target location, to check for consistency, before moving on to the next target port.

• IF the beam is too far above or below the horizontal line, proceed to section 7-10-2.

• IF the beam position changes each time you repeat the test, call support.

43. Test each occupied target port on the system, including position five (proton target).

• Use a tool to shift the Paper Burner from one position to the next.

WARNING RADIATION! REMEMBER, THE PAPER BURNER TARGET BECOMES INCREAS-INGLY RADIOACTIVE THE LONGER YOU USE IT. ALWAYS USE A TOOL TO MOVE THE PAPER BURNER FROM ONE TARGET PORT TO ANOTHER. WHEN YOU FIN-ISH THE TEST, STORE THE PAPER BURNER IN A LEAD CONTAINER.

7-10-1 Resize the Collimator Opening

Follow the procedure in this section to reposition the collimator, to raise or lower the point where the beam strikes the target, without changing the collimator diameter.

Liquid targets are pressurized with helium to increase the boiling point of the target liq-uid. The gas forms a bubble at the top of the target chamber. The collimator is posi-tioned to direct the beam below the center point of the target, to avoid this bubble.

On gas targets, the collimator is positioned to direct the beam to the center of the tar-get.

1. Measure the collimator opening with calipers to determine the factory setting.

• The standard collimator diameter is about 6mm, but could be as large as 8mm.

Top




2. Look at the burn mark on the paper target.

• IF the top of the liquid target burn mark -or- the center of the gas target burn mark falls below the horizontal line, raise the entire collimator.

• IF the bottom of the burn mark -or- the center of the gas target burn mark falls above the horizontal line, lower the entire collimator.

3. Determine the distance to move the beam.

a. Measure the distance between the actual and optimal burn mark location.

b. Divide this value in half. (Refer to the example on the next page)

4. Use metric drill bits to reposition the collimator while maintaining the original diam-eter.

Remember to keep the drill bits perpendicular to the angled target port when you insert them into the collimator opening to make the adjustments. (Refer to Illustration 7-28 and the example, on the next page.)

Example: The burn mark is 2mm too high, and the collimator diameter is 6mm.To shift the collimator down 1mm:

1. Loosen the bottom collimator blade.

2. Insert a 7mm drill bit into the opening, move the bottom blade against the bit and tighten into place.

3. Loosen the top collimator blade.

4. Insert a 6mm drill into the opening and move the top blade against the bit .

5. Tighten the top collimator blade.

6. Return to 7-10, on page 235.

Notes and Comments:



Appendix B —Connectors 267

APPENDIX B — CONNECTORS

B-1 Swagelok Tube Fitting ConnectionsThe 1/16", 1/8" and 3/8" lines use Swagelok Tube Fittings. This section contains a set of installation instructions for all three sizes. The connections are the same for all the types of pipes and tubes used on the system. However, the size of the pipe or tube determines

whether you tighten the nut 270o (3/4 turn) or 450o (1 and 1/4 turn).

Note: If you haven’t used a Swagelok tube fitting before, take one apart and examine the pieces. (Look for the shoulder, inside the Swagelok body) Put the fitting back together, and follow the instructions to insert the hose. Stop after Step 5 to exam-ine your work. After you make a couple of connections, you’ll get a feel for the pro-cess, and won’t have to check the clearance on the ferrules each time.

1. Make sure the end of the pipe or tube is round, has an even edge, and is free from burrs.

2. Refer to Illustration B-1. The pre assembled Swagelok connector consists of a body, two ferrules and a nut. The back ferrule fits into the front ferrule, and the both fer-rules nest inside the nut. There is also a tube insert to secure the tube connection.

4. Loosen the nut, without removing it from the body, and push the tube or piping into the back of the nut, through both ferrules, until it just reaches the shoulder in the Swagelok body.

5. Then back off a millimeter or two. The end of the tube should clear the front ferrule by 2 or 3mm, but should not touch the shoulder in the Swagelok body. (Illustration B-1 and Illustration B-3)

• To check the clearance, remove the nut and push on the hose to expose the ferrules.

• The hose end should extend 2 or 3mm beyond the end of the front ferrule.

• If OK, pull the hose and ferrules back into the nut and reattach it to the Swagelok body.

ILLUSTRATION B-3HOSE CLEARANCE EXAMPLES

ILLUSTRATION B-4SWAGELOK COMPONENTS IN CORRECT ORIENTATION

6. Tighten the nut until it feels finger tight.

7. Make a reference mark on the tube at the 6 o’clock position.

Bad: Not enough clearance OK: Hose extends 2mm past the end of the front ferrule

After you OK the hose clearance, pull the ferrules back into the nut.




8. Hold the fitting body steady with one wrench and tighten the nut with another wrench:

• IF the pipe/tube has a 1/16" or 1/8" diameter, tighten the nut 270o (3/4 turn)

• IF the pipe/tube has a 3/8" diameter, tighten the nut 450o (1 and 1/4 turn)

B-2 PEEK ConnectionsThe 18F- and 13N Target systems use PEEK tubes between the Liquid Target Filler and the Target. The LTF also has additional PEEK tubing and connections. Usually, the 1/16" PEEK tube uses the same Swagelok connectors as the 1/16" Tefzel tubes (B-1), but the PEEK tubes also use connections like the one shown in Illustration B-7 to provide a quick method to disconnect the Target from the LTF. The LTF vials also use needles with a sim-ilar fitting.

B-3 RF CableThe RF cable consists of a hollow inner copper conductor centered within a hollow outer copper conductor, and held in place with a spiral plastic spacer. Both conductors have corrugated ribs that act as threads. The RF cable arrives in a coil, usually with a connec-tor attached to at least one end.

• IF the cable has a connector attached to both ends, return to section 4-1-3.

• IF you must attach one or both connectors, follow the instructions in this sec-tion.

Note: You must take two restrictions into consideration to determine the length of the RF cable.

1. The cable may only be cut in increments of 1.41 meters (including the connectors)

2. You may not make a bend in the cable with a radius of less than 180mm (single bend) or 550mm (multiple bends).

Read all the information in the entire RF cable section (Section B-3-1 through B-3-3) at least once before you remove the ty-wraps and run the RF cable.

For best results:

• Decide how to run and suspend or support the cable from the RFPG to the top of the Cyclotron shield. Most MINItrace systems have the electronics cabinets in the same room as the Cyclotron, so the run should be fairly short and straight.

• Measure the length of the planned cable run and round it up to the nearest seg-ment.

• Measure and cut the cable to length.

• Cover the unfinished end, to prevent any dirt or debris from entering the cable.

• The finished end should have about 50mm of insulation removed from the cable (about 20mm above the connector). Attach this end to the RFPG cabinet connec-tion.

• Run the RF cable from the RFPG to the top of the MINItrace shield.

• Don’t make the RFPG connection until after you finish the cable end at the magnet.

• Insert the unfinished cable end into the shield first, then attach the connector.




ILLUSTRATION B-10COILED CABLE

B-3-1 Determine the RF Cable Length

Normally, the run between the RFPG cable and MINItrace Cyclotron is fairly short and straight, because the electronics cabinets are usually located in the same room as the Cyclotron. If the cabinets are located in a different room, you may have to make some extra bends in the cable. Refer to Illustration B-10. Examine the coiled cable before you cut the ty-wraps. If you make bends in the cable with a sharper turn, the bends become permanent. So, rather than bending the cable around a corner, you must curve the cable around it. (REMEMBER to add the excess length of this curve to the cable measure-ment.)

Note: To negotiate a really sharp turn, you may have to make a cut in the cable, and

insert a 90o connector. If this is the case, call the factory in Uppsala for advice and information.

IF possible, make a dry run and measure the distance on the RF cable. Otherwise, use string (rope) or one of the other cables to make the run and measure the distance.

• Refer to Illustration B-10. If you make any bends with a smaller radius than these loops, the bend becomes permanent. Plan every bend carefully.

To determine the final cable length:

1. Measure the exact metric length of the cable run you plan to follow, from the con-nector on the RFPG cabinet to the connector on the magnet (Illustration B-11), including the extra wide curves and loops needed to negotiate corners or complex penetrations.

2. Round this figure up to the nearest 1.41meter increment

• Ex: 5.64, 7.05, 8.46, 9.87, 11.28, 12.69... up to a maximum length of 25.38m

3. Measure the cable one more time, and cut the cable to length.

Sharper bends than this become permanent.Make a curve in the cable to negotiate asharp turn, or follow an alternate route.




ILLUSTRATION B-11RF CABLE CONNECTION TO MAGNET

B-3-2 Locate and Disassemble the Connector

Locate the RF Cable connector. The connector ships, pre-assembled, in a plastic bag, along with a set of generic instructions. This section contains the specific instructions for this application.

The connector consists of:

• A termination sleeve that fits over the outer conductor and rests against the cable insulation.

• A threaded socket that screws into the inner conductor.

• An inner subassembly that fits over the inner conductor and threaded socket.(You do not have to remove the inner subassembly from the connector head when you disassemble the connector.)

• An o-ring gasket seal between the termination sleeve and connector head.

• A flanged connector head that slides over the inner subassembly and fastens to the termination sleeve with six cap head screws.

• Six cap head screws and washers, and one left-threaded screw and copper washer.

• Two black plastic plugs and a copper gasket (not used).




ILLUSTRATION B-12RF CABLE CONNECTOR

1. Remove the connector, instructions and bag of hardware from the plastic bag.

2. Use a 5mm allen wrench to remove the two cap head screws that hold the assem-bly together.

3. Remove the left threaded (5mm) cap head screw from the connector head, and remove the threaded socket from the center interior of the connector head.

4. Locate and remove the following items from the installation gang box:

• 35mm pipe jig (See Illustration B-13)

• Hacksaw

• Flanging tool (Refer to Illustration B-14)

• Adhesive bandages and ointment (See Caution)

CAUTION The edges of the RF cable are sharp enough to cut flesh and tear clothes. Take care when you handle or cut the conductors, or attach and remove the flanging tool.

B-3-3 Attach the Connector to the Cable

Cut the Cable to its Finished Length

The actual length of the RF cable equals the distance from the outer connector edge to outer connector edge. So, the first step is to cut 80mm (8cm) off the unfinished edge, to compensate for the length added to the cable by the connector head.

1. Measure 80mm from the unfinished edge of the cable and mark the cable for cut-ting.

2. Measure 55mm from the cut mark, and evenly wrap a piece of masking tape around the cable, so the upper edge meets the 55mm mark.

3. Cut the cable at the mark you made 80mm from the unfinished edge.

• Try to make a straight (perpendicular) cut.

• If possible, stuff a cloth into the cable opening and/or tilt the cable downward so the debris (swarf) created while cutting stays out of the interior of the cable.

4. After you make the cut, tap the cable against a solid surface to remove any chips from the interior of the conductors.

ILLUSTRATION B-15UNFINISHED CABLE END WITH 55MM GUIDE

Remove the Insulation from the Outer Conductor

1. Remove the cable insulation from the newly cut edge, to the masking tape at the 55mm mark.

• Using the tape as a guide, take a knife or razor blade and trim the insulation as evenly as possible along the edge of the tape, and as perpendicular as possi-ble to the outer conductor. The goal is to create an even and solid edge to butt against the termination sleeve.

2. Clean the sticky black adhesive substrate (glue) off the outer conductor with sol-vent.

• If available, use a heat gun to loosen (and melt) the adhesive. Take care not to warp the remaining insulation with the heat gun.

ILLUSTRATION B-16RF CABLE WITH INSULATION REMOVED AND OUTER CONDUCTOR CUT TO LENGTH

Cut the Outer Conductor to Length

1. After you clean the adhesive from outer conductor, tap the cable against a solid surface to remove any debris from the interior, then gently clamp the cable into the vise.

2. Refer to Illustration B-13. Slip the pipe jig over the end of the cable, and slide it down the outer conductor until the inner shoulder rests firmly against the edge of the insulation.

3. Insert the hacksaw blade into the slot, and cut through the outer conductor.

4. Keep turning the jig and, if necessary, adjusting the hacksaw blade, to trim away the excess 20mm of outer conductor, while leaving the inner conductor intact.

5. Use diagonal cutters to trim back any excess spiral plastic spacer.

6. Refer to Illustration B-17. When you finish, the outer conductor should measure 35mm from insulation to outer edge. The inner conductor should now stick out an additional 20mm from the outer edge of the outer conductor.

ILLUSTRATION B-17CUT OUTER CONDUCTOR TO 35MM

Attach the Termination Sleeve to the Cable

1. Refer to Illustration B-18. Slide the Termination Sleeve over the end of the cable, until the threads in the outer edge engage the corrugated ribs of the outer conduc-tor. Then, screw the termination sleeve onto the outer conductor, until the inner edge of the sleeve rests against the cable insulation.

2. Refer to Illustration B-14. The Flanging tool has a flanging wheel and a cutting bit attached to the knurled assembly on the handle. Pull up on the knurled assembly and rotate it to position the flanging wheel as close to the collar as possible. (Later, you will rotate the cutter into position to trim away the excess copper from the outer conductor)

3. Refer to Illustration B-14 and Illustration B-19. The collar of the flanging tool has 4mm cap head captive screws. Slip the collar of the flanging tool over the end of the cable, and attach it to the Termination Sleeve with the captive screws

ILLUSTRATION B-19ATTACH FLANGING TOOL TO TERMINATION SLEEVE

4. Refer to Illustration B-20. Slowly swing flanging assembly upward, and see if you can slip the bar on the assembly into the notch on the collar. (If you followed the instructions, you probably can’t .) Trim away a millimeter or two of the inner con-ductor with the hacksaw, and try again.

• When you finish, the inner conductor should rest against the flanging assem-bly and the bar should drop into the collar. Don’t fasten the bar into place yet.

The corrugated ribs of the outerconductor act as threads. TheTerminator sleeve screws ontothe outer conductor.

5. Refer to Illustration B-20 and Illustration B-21. Turn the notched wheel at the bot-tom of the flanging assembly to position the flanging wheel between the inner and outer conductors. Then drop the bar into the notch on the collar. Carefully tighten the knurled screw on the bar to snug the assembly into place. When you finish:

• The inner conductor should just rest against the flanging assembly.

• The flanging assembly should be parallel to the collar/termination sleeve.

• The flanging wheel should be positioned between the inner and outer conduc-tors, with the edge resting lightly against the outer conductor. (Notched wheel adjusts position)

• The bar should fit all the way into the notch on the collar, perpendicular to both the collar and the flanging assembly.

ILLUSTRATION B-21EXTREME CLOSE-UP OF FLANGING WHEEL

6. Refer to Illustration B-20 and Illustration B-21. Turn the handle slowly and smoothly.

• As you turn the handle, the flanging tool folds the outer conductor back against the Termination Sleeve without splitting the conductor. Then, it presses the conductor firmly against the Termination Sleeve, which in turn presses the Termination Sleeve firmly against the insulation.

• If necessary, adjust the notched wheel to change the relationship between the flanging wheel and the outer conductor (increase or decrease the pressure.)

7. Continue to turn the handle and adjust the notched wheel until the flanging wheel has completely flattened the outer conductor against the Termination Sleeve.

8. Loosen the screw and temporarily slip the flanging tool bar out of the notch on the collar. Pull up on the knurled section of the flanging assembly and rotate the flang-ing wheel out of the way, and the cutting bit into its place.

9. Reattach the bar to the collar, and adjust the notched wheel until the cutting bit rests against the folded back portion of the conductor.

10. Refer to Illustration B-22.Turn the handle slowly and smoothly. The cutting bit trims excess material away from the flanged portion of the conductor as you turn the handle. The edge is still sharp, so take care.

11. After you trim excess copper from the flanged edge, you may remove the flanging tool from the Termination Sleeve.

• Loosen the knurled screw, remove the bar from the notch in the collar, and let the flanging assembly hang from its hinge.

• Loosen the 4mm cap head screws to detach the flanging tool from the Termi-nation Sleeve.

• Move the flanging wheel back into its position nearest the collar, to set the flanging tool up for the next connector, before you return the tool to the box.

Position flanging wheel betweeninner and outer conductor beforelocking flanging assembly bar into place.

The flanging wheel presses the edgeof the outer conductor against theTermination Sleeve to fasten it into place.

6. Remove the o-ring gasket from the parts bag, and slip it into the groove beneath the outer lip of the Termination Sleeve.

7. Slide the Connector Head over the Termination Sleeve and Threaded Socket assem-bly and align the holes in the Connector Head with the threaded holes on the Termi-nation Sleeve.

• Slide a steel washer down the shaft of each of the six 5mm cap head screws.

• Fasten the Connector Head to the Termination Sleeve, and use your fingers to start the screws, and barely fasten them into place.

8. Use a 5mm allen wrench to cross-tighten the screws:

• Tighten down one screw, then tighten down the screw directly opposite it

(180o).

• Continue to fasten down each pair of screws, until all three sets are firmly fas-tened. (When you tighten one set of screws, the other two sets will become loose until you’ve completely clamped the Connector Head to the Termination Sleeve, and compressed the gasket.)

• When all three sets of screws feel tight, try each screw in turn, until you have "tightened" your way once around the circumference of the Connector Head. Try the first screw again, and if it moves, tighten once more in the opposite direction around the circumference of the Connector Head.

9. Slide the copper washer down the shaft of the left-threaded screw, and insert it into the center of the connector head, and into the Threaded Socket you inserted into the inner conductor.

10. After you firmly tighten the left-threaded screw, remove the two black plugs from the parts bag, and insert them into the threaded holes in the Termination Sleeve. (All you should have left over is a copper gasket.)

ILLUSTRATION B-26FINISHED CABLE

Gas fitting not used; you may remove it if it gets in the way when you run the cable.




Expose the Conductor at the RFPG End of the Cable

If you had to attach both connectors to the raw RF cable, you must expose 50mm of the outer conductor at the RFPG end of the cable to make the grounding connection at the top of the cabinet. If the cable arrived with one connector attached, the conductor should already be exposed at the finished end. Attach the end with the exposed conduc-tor to the RFPG cabinet connector after you make the connection at the magnet end.

1. Measure and mark the first cut line 20mm from the edge of the connector.

2. Measure and mark the second cut line 70mm from the edge of the connector.

3. Evenly wrap a piece of masking tape around the cable and along the edge of each cut mark, exposing the 50mm of insulation you will remove from the cable.

ILLUSTRATION B-27EXPOSE THE CONDUCTOR AT THE RFPG END OF THE CABLE

4. Using the pieces of tape as a guide, take a knife or razor blade and trim the insula-tion as evenly as possible along the edge of each tape, and as perpendicular as possible to the outer conductor.

5. Remove all the insulation from the 50mm area between the two pieces of tape.

6. Clean the sticky black adhesive substrate (glue) off the outer conductor with sol-vent.

• If available, use a heat gun to loosen (and melt) the adhesive. Take care not to warp the remaining insulation with the heat gun.

7. Remove the tape and fasten the finished cable to the RFPG cabinet connector.

8. Refer to Illustration B-28. Fit the grounding collar plates around the cable, and make sure they fit against the exposed conductor.

• If necessary, trim back any excess insulation until only exposed conductor makes contact with the grounding collar.

9. Return to Section 4-1-3 on page 99 to install the RF cable.

Appendix G —RFPG Transformer Taps 309

APPENDIX G — RFPG TRANSFORMER TAPS

G-1 IntroductionThis instruction provides the information to determine the mains selection, in order to configure the RFPG taps to a particular mains supply

The RFPG cabinet has only one transformer, the EHT Transformer T1, which requires its taps to be set. The EHT Transformer T1 is a three phase transformer, located in the TPSU, and accessed from the bottom front or rear panels of the RFPG. The EHT trans-former is used to generate the anode voltage for the power amplifier tube.

All the other RFPG components are powered from the mains transformer in the Control Cabinet (CCAB). This appendix does NOT address the tapping of the CCAB transformer.

If the mains voltage is low (108 V – 132 V phase to neutral) you must change the mains circuit breaker SW1, and the mains filter FL1 in the RFPG, before you can set the EHT Transformer taps.



310 Appendix G —RFPG Transformer Taps

G-2 Measure the Site Main Voltage

DANGER THIS PROCEDURE REQUIRES THE MEASUREMENT OF DANGEROUS MAINS VOLTAGES. THE TPSU GENERATES LETHAL VOLTAGES OF UP TO 8KV DURING NORMAL OPERATION. ALWAYS CONNECT THE GROUND STICK TO THE HIGH VOLTAGE FUSE, F1 BEFORE YOU TOUCH ANY RFPG COMPONENT.

ILLUSTRATION G-1GROUND STICK LOCATION

G-2-1 Measure the Incoming Power

1. Open the lower rear panel of the RFPG.

2. Find the TB4 terminal blocks, located in the left rear side of the TPSU.

3. Use a digital voltmeter, with better than 1.5% accuracy on r.m.s. a.c. voltage for this measurement.

• At the TB4 terminal blocks, measure the phase voltages, L1 – N, L2 – N and L3 – N.

• Neutral N is not required for the RFPG EHT transformer, so some installations may not have a neutral connected to TB4. If so, measure the line voltages L1 – L2, L2 – L3 and L1 – L3. Calculate the phase voltages by dividing the line volt-age values by 3

HV fuse

Ground stick

TB4 Filter FL1




G-2-2 Determine the Average Voltage and Fluctuations

1. Record the three phase voltages as VPL1, VPL2 and VPL3.

2. Use the following formula to calculate the average phase voltage VPA.

VPL1 + VPL2 + VPL3

VPA = ________________

33. Record this value.

Attempt to obtain information about the loading of the installation mains supply, so you can take measurements during peak and minimum loads. From the results determine minimum and maximum values VPAMIN and VPAMAX.

4. Use the following formula to calculate VPAMEAN

VPAMEAN = (VPAMIN + VPAMAX)/2

5. VPAMEAN equals the mean value of the mains voltage.

- Preferably the minimum and maximum values of the mains voltage should not differ by more than 5% from the mean value.

- Section elect tapping configuration according to section 3 of this instruction.




G-3 Set the Taps

WARNING ENSURE THE RFPG IS ISOLATED FROM THE MAINS BEFORE ATTEMPTING TO SET THE TAPS.

CAUTION Open TPSU front cover and check, using a screwdriver, that all terminal screws on terminal block TBL 1, TBL 2 and TBL 3 are tightened. Loose screws might cause bad connections.

G-3-1 Overview

Notice All Mains voltage values refer to voltages from phase to neutral.

1. Refer to Table G-1 . Use the value VPAMEAN, calculated in the previous section.

2. Find the nearest value to VPAMEAN in the Table G-1 .

3. Proceed to the corresponding "Tapping Configuration" figure which provides the information to configure the transformer.

- A configuration could entail the fitting of up to 5 links per terminal block. The links are supplied attached to the RFPG. Please retain the spare links in case the mains supply changes and a new configuration is required.

- Furthermore, for each particular mains voltage, terminals have to be chosen on the transformer for the incoming phase leads.

Notice Read Section G-4 before proceeding further.

G-4 Procedure to Replace SW1 and FL1 Follow the procedure in this section to replace circuit breaker, SW1, and Mains filter, FL1, for higher current operation.

If the VPAMEAN is such that its nearest value is 112, 120 or 128 V then the circuit breaker SW1 at the front of the TPSU must be changed to a higher rating, or it will continually trip. You must also change the Mains filter, FL1, to a higher rating.

• Refer to parts list CAC223-36005-xx-4 for the circuit breaker SW1 part information.

• Refer to parts list CAC223-36000-xx-4 for mains filter FL1 part information.

Notice Please follow the instructions in Section G-4-1 through G-4-3 to replace SW1 and FL1.

G-4-1 Procedure
