MuCool Outlook and Plans

Over the past year we have had a very successful program that will be detailed in the next two sessions:

MuCool Test Area – Popovic Beamline Instrumentation – Hoffman RF – Moretti, Norem, Li LH2 Absorbers – Cummings, Lau, Darve Gaseous H Absorbers – Johnson MuScat – Rakhno

MuCool Test Area is now complete

Setting up for KEK LH2 absorber tests and RF

MuCool Outlook and Plans

KEK Test First test of LH2 Absorber Setting up in MTA

First Tests in March

MuCool RF Test Program

MuCool has had a very active test program using the Lab G facility

Tests: Open Cell Cavity

54 MV/m Closed Cell Cavity

34 MV/m High Pressure H2 filled test cell

80 MV/m Investigate materials, surface coatings,

window design, B field effects, pressurized cavities

MuCool Outlook and Plans

RF Testing This past year tests have focused on

805 MHz studies of the single-cell –closed cell cavity

Window design– Materials– Surface treatment– Damage mechanisms

Our one major setback has been the premature deactivation of the Lab G test area

Due to problems with 805 MHz Klystrons in the Linac, the Lab G Klystron (+system components) has be removed and sent back to the Linac.

Lab G is now decommissioned

The loss of Lab G has a serious impact on the MuCool RF program

MuCool RF Test Program

Our activities were limited during the Tevatron shutdown due to the in-availability of cryo support to cool down superconducting magnet.

A rather aggressive program was planned for the Lab G facility starting in January

Using Closed Cell Cavity in B field Aluminum grid “window” Curved SS window Chromium window Hollow Aluminum grid w/ gas cooling Curved Be windows “Button-Cell” material tests High Pressure H2 cavity tests

This was estimated to be a 6-9 month program

Fall 04 we will receive the first 201 MHz test cavity

Shift R&D focus to 201 MHz tests

MuCool RF Test Program

In addition to the impact on direct MuCool activities, loss of Lab G impacts

IIT PhD student Mechanical and EM studies of grids Current situation will present some

delay – need to minimize impact on student

Muons Inc. High Pressure H2 filled cavity Working within a 2 year schedule

(from Aug 03). 6-9 delay would have severe impact on their likelihood for successful completion within this time limit.

With Lab G de-commissioned, we would like to bring 805 MHz (& 201 MHz) test capability to the MuCool Test Area As Soon As Possible

MuCool RF Test Program

Lab G Magnet

Initial MTA Setup

MuCool RF Test Program

In order to get back “on-line” - Desired schedule with required effort

Jan 19th start (1 month duration) Design and install weather shield over RF

trench in MTA. – 1 mm + $5k

March 1st start (1 month duration) Install 805 MHz waveguide and 201 MHz

coax– 4 mm + $1k

March 22nd start (1 month duration) Remove vacuum and water systems from

Lab G and install in MTA– 4 mm + $5K

March 22nd start (1 month duration) Install water mains, electrical panels,

cables, data network in MTA– 4 mm + $15k

May 1st Testing can commence in MTA

Need the manpower resources from Fermilab, M&S shown above likely covered within existing MuCool budget

However, FY04 MuCool budget does not cover the cost of moving magnet from Lab G to MTA

$15-20k

MuCool RF Test Program

Once the 201 MHz prototype cavity arrives at Fermilab in Fall 04, our focus shifts to 201 tests

If we do not have most of the 805 program complete by this time, finishing it will be delayed significantly

Additional complication is working in the KEK absorber tests. Cannot run RF & LH2 together

First round of KEK LHs in March 805 Testing May-Sept (Possible 2nd KEK test)

in this time window also possible We anticipated that 805 MHz testing will

continue once the 201 MHz program begins, but at a much reduced level of effort.

KEK absorber tests complete Our goal is to re-established 805 MHz

testing as soon as possible while not jeopardizing having 201 MHz capability in the MTA by Sept 04

We have met with Fermilab AD management and we have been given assurances that they will do whatever that can to get the MTA RF test program operation as soon as possible.

Mechanical/electrical resources (technicians) Cryo (move of Lab G magnet) Safety analysis

FY 04 Budget and Plans for Fermilab

Goals for FY 04 Provide 201 MHz (and 805) RF

capability for MTA Move RF studies from Lab G to the

MTA Support Japanese convective

absorber test in MTA Finish installation of as much of the

cryo-system for the MTA as possible.

Costs MTA overrun

(HVAC) $70k RF(MTA)

Waveguide hardware $10k– ($70k covered in FY03)

Vacuum System 30k Water & AC power 25k Waveguide Trench 50k Contingency 40k

FY 04 Budget and Plans for Fermilab

Costs Cryo (MTA)

Compressor and Refrigerator193k

Flow Absorber/Hydrogen system 81k

FY 04 Budget and Plans for Fermilab

Lab G (goes to MTA) Instrumentation

25k– Microphones– Thermocouples for window– Optical system to measure window movement– DSO (on loan from other group – they want it back

LHe 50k

Move Magnet to MTA 20k Japanese absorber tests

LHe transfer line and boxes 10k Quad-log software 3k Misc. cryo 2k Electrical 3k LHe

30k Total Costs $771k Funding:

FY 03 US-Japan $49k Should cover convective absorber test

MTA Contingency 50k RF trench

FNAL TD FY 04 50k FNAL BD FY 04 50k

LHe costs FY 04 US-Japan ? MC 385k

FY 04 Budget and Plans for Fermilab

Total Funding: $584 + ? The difference will have to come out

of cryo implementation for the MTA – impact start of construction of flow-absorber

Have asked AD to support moving Lab G magnet

Some savings in LHe costs – MTA cryo plant to come on sooner possibly

Delay construction of Flow-absorber until FY 05

Hope to start in this year Conceptual design mature Detailed engineering can still be

done in FY 04 is manpower is available.

Funding short-fall only implies construction delay

MuCool Outlook and Plans

Conclusions Although the loss of Lab G will lead

to some scheduling difficulties over the next 6-9 months

KEK 805 MHz RF Testing 201 MHz RF Testing

We anticipate being able to complete the KEK LH2 absorber program and 805 MHz RF test program and still be ready for the 201 MHz cavity when it arrives in the Fall of 04

Expecting Fermilab AD to assist in all ways possible to bring RF testing to the MTA by May

Scheduling is an issue, the Budget is tight, but should be able to do most of what we want to do in FY04

Some additional funds could help flow-through absorber program
