Sourcing and Source Driver Status

Outline

• Air Drivers• Air system• HF Source tubes and drivers• Control electronics• Software• Miscellaneous issues

Air drivers

HE Air drivers:• All Air drivers installed and tested for proper operation.• Two complete rounds of scans performed on all 432 tubes, and

maps of tubes lengths established.– 3 tubes found to be broken. 1 replaced, other two blocked at indexer.– 4 tubes can not be penetrated.

HB drivers:• New driver supports produced to accommodate shift in Z of indexer

bars from their nominal positions.• All air drivers installed and tested for proper operation.• Two complete rounds of scans performed on all 432 tubes, and

maps of tubes lengths established. – 4 tubes can not be penetrated.– 4 tubes may be broken (wire went beyond expected length).

– Reel air motor on the HB- near side driver jammed. Motor was replaced.

– residue was found in the motor. May have been present before installation, but there is concern that it may have come from the flexible hosed that go between the regulator/filter and the driver. Note that HE has copper pipes.

Air system

•All on-detector air panels completed and installed

Lock out valves

Filter20u

• Hoses between UXC X0 and gas room not installed!

Hoses need to be procured and installed

DONE

• Need to procure components and prepare panels for Installation in the USC gas room

HF source system.• All drivers installed and tested for proper operation.

• Two complete rounds of scans done on all 1152 tubes, and tube length maps established.

• No failures or broken tubes.

• Wire reached the end of all tubes (few tight ones).

Test scan results for wedge 1-10

Control electronicsController boards:• Crate and panel parts kits procured.• Electronic components procured, except microcontroller chips!

– Philips microcontroller out of production. NXP replacement not completely compatible as claimed –poor documentation of changes! Requires some circuit modifications to avoid potential problems with the NXP devices.

– Plan to try and procure original Philips devices, but also implement changes for NXP device compatibility.

• Boards layouts completed (except for mods for NXP devices)

Backplane boards:• Backplane schematics captured, parts list generated, and layout started.

To Do:– Produce prototype boards.– Assemble Crates– Build interlock interface.

• Need to finalize interconnection of zone safety infrastructure (switches, locks, lights…).

*Note: We have prototype boards at CERN for used until production items are available.

Software

• Controller code revised when new boards available.– NXP devices require code changes. – Some differences between Philips and NXP devices not properly

documented!

• XDAQ Software started, and a test stand environment setup on MOE6.

Still lots of work for me to do here.

Miscellaneous issues

• Storage/transport boxes (2+3+4+3+2 =14 min.):– Lead storage pigs produced and installed in boxes (Old HO RBX

boxes).• Need to procure some hardware to complete assembly.• Need wire retaining mechanism to prevent wires from coming out of pigs.

• Zone interlocks, access control, safety and procedures:– HCAL responsible for access control interlock, and associated warning

lights. – Interlock box specification needs to be established. Fermilab will

produce boxes.

– Need revised procedures to fully address the requirements and specific implementation in the UXC environment (Pawel).

Info related to damaged tube on HE+

Marks suggest external damage
