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
LHe Transfer line 64k
Flow Absorber/Hydrogen system 81k
Contingency 65k
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
