• Discussion of FY01 Budget and Goals for RF Structures


fFY01 LC R&D Goals / Technical Division

• RF Structure Factory• Make first Fermilab Xband structure

• By about mid-March01 or so (we hope)• (See below also)

• Occupy IB4 SW Corner• Finish RF QC Lab

• Need expertise from BD and TD• Using expertise from INR Collaboration (see

later slide)• Now have BD Network Analyzer from BD

(Thanks, John)• Need a second NA bySEP01 (Peter?)

• Get first furnace operating• Full Size Furnace by SEP01 (we hope)• Baby Furnace (~120K$) by APR01

• Magnets• Finish four prototypes• Measure with mostly existing equipment• Take over some motion control

development• Understand beam alignment

requirements

• Collaboration High Gradient Tests• Have made, now send, 20 disks to

SLAC• First, we do RF QA on them• SLAC provides couplers etc and

assembles into a complete structure• “Same as” SLAC / Robertson model

• Make two entire “20 cell” structures• aka “1st Fermilab Xband structures”• To get on SLAC “High Power Testing”

List, need to “Show me the structure!”

• IB5 CDR w/ FESS• $25K from RAT, $25K from TD• Assembly Line for beam line units• Not necessarily “NLC Project” building

… could instead be for additional space needed for ongoing TD activities


fIndustrial Building 4 (IB4)

Notes:

1. Southwest Corner is lower right of picture

2. RF structure work

- Uses all of SW corner (2 clean rooms, rf lab, work area, furnace area)

- Shares QC Laboratory for mechanical QC

- Shares Machine Shop

3. This is not an optimum arrangement for the work flow for making structures

4. “Beam Line Unit” Assembly area would occupy most (if not all) of IB4


fIB4 SW Corner

Note: Furnace area is large enough for baby furnace … full size furnace is mounted over Clean Room B (the one on the left)

Copper parts go in … structures come out


fINR Collaboration (Troitsk, Russia)

• Reference: Finley to Yarba 12/20/00 email “INR and TD”

• Item 1: In support of the RF QC Lab

• Gennady Romanov (TD Guest) coordinating the setting up of the RF QC Lab

• with Ding Sun (BD), Tug Arkan, Brian Smith, Evgueni Borissov(TD)

• What is to be done in IB4?• Short stack and full length structure

measurements• plunger and bead pull techniques

• FY01 New Guests• Gonin: rf calculations to help

understand measurements• Khabibulin: improve throughput (aka

automation)• 3rd person: Brazing

• Small piece of hardware from INR

• Item 2: In support of understanding structure vacuum

• To be done at INR• Develop realistic and useful

computer codes• Start with 1.8 meter RDDS as

specific example at appropriate level of detail

• Example: Model the time development of the vacuum after a discharge and outgassing

• How fast does the gas move?• Which direction?• How long does it take to pump

down so that processing can continue?


fFY01 LC R&D Goals for TD / Background

• Budget $1.3M• Top Down (see slide from LaDaune T.)

• Magnets (MAT)• $195K Salaries, $70K M&S

• RF Structures (RAT)• $540K Salaries, $495K M&S

• Sum• $735K Salaries, $565K M&S

• Caution: November 2000 obligations already close to linear budget for FY01 …

• Develop funding “understandings”

• ~100K$ TD Equipment for Baby Furnace• “Small%” FTEs not charged to LC R&D?

• Have made no changes in TD reporting yet, small changes might be needed.

• ~$75K TD Equipment for 2nd Network Analyzer

• ~$600K Full Size Furnace - NIU funds

• Update multi-year plan• Integrate into SLAC tests

• Make Structures so that SLAC can do High Gradient tests on them

• Integrate into ETF• Will force 1 structure / month issue• Will force “beam line unit” issues into

the open

• Integrate into Industry• Need to determine appropriate strategy

for scaling up industrialization issues• Need to determine sensible role for

SBIRs

Note on throughput:

R&D needs about 1 structure / month

Project production rate is ~ 6 structures / day

fFY01 LC R&D … Waiting in the Wings

• Windowtron R&D• $100K M&S estimate• “Windowtron” = single cell (or less) rf

breakdown studies led by SLAC• Grew out of breakdown workshop• Miss opportunity for more global

involvement (CERN, Cornell, Fermilab)

• Moderately Damped Design• … at least not under TD leadership• ~ 0.5 FTE

• Beam Line Unit Design• Unit = “rf structures and a magnet”

on a support girder• Unit is “repeated” throughout linac• Need final structure design (Q: “Are

there three or four per unit?)• “Generic design” for support girder is

not appropriate• ~1 FTE

• Parametric Study on Bonding• $75K to $150K M&S estimate• initiated in FY00 when RDDS structure

design was thought to be final ...but is actually premature at this time

• “Parametric Study” = systematically map out costs of producing disks vs required performance of bond joints

• but will need to be done to determine a defensible cost estimate of the full linac … once a structure design has been determined

• settle the issue of brazing vs. bonding

• Equipment, equipment, equipment ...

• optical measurements (>~ $200K)• laser interferometer for magnet

measurements (~$150K)
