Outline
• A Description of HPTF and Its Goals• HPTF Plan
– General Design Philosophy– Schedule Requirements– The HPTF Plan– Major Risks– Conclusions
May 11, 2005P. Limon --- Accelerator Advisory Committee 3Fermilab
What Is HPTF?
• HPTF is a high-power testing subset of a national superconducting RF R&D effort.
• HPTF will be located at Fermilab.– The Proton Driver and Single-Module test areas will be in the
Meson Detector Building to take advantage of available cryogenics
– The High-Brightness Photoinjector and ILC areas will be in the New Muon Lab to take advantage of the excellent space.
• HPTF supplies infrastructure including space, cryogenics, power and other utilities, controls, radiation shielding, etc., for complete high-power tests.

HPTF Goals
• Guiding Principles– HPTF will be inclusive of many different types of
modules, <1, =1, and CW– HPTF should not be the cause of delay in the initial
testing program. Be ready when modules are available to test.
• The tests will include:– High-power pulsed and CW RF tests of modules– High-power pulsed and CW tests with beam
May 11, 2005P. Limon --- Accelerator Advisory Committee 5Fermilab
A Plan for HPTF
• Distribute HPTF to Several Locations– The Proton Driver front end and all single-module tests
(without beam) will be at the Meson Lab– The Photoinjector and ILC beam tests will be at the New
Muon Lab– A temporary cryogenic system is required at NML to
meet the schedule. There are two options:• Dewar or tanker-supplied helium and a gas recovery system
in Lab B, or• a satellite refrigerator at NML and compressors at Lab B

Temporary cryogenic system operational at NMLHigh-power modulators & klystronsComponents for upgrade of PI (e.g. 3.9 GHz cavities, etc.)Beam handling capability
3.3 Begin operation of PI with four ILC modules Jul. 2009Major Requirments
New refrigerator and cryogenic system at NMLTunnel extension of NMLAdditional modulators & klystrons

The Meson Lab
• Advantages– There is an existing cryogenic system
• 1500 W capability at 4.5 K• Or 60 W capability at 2 K with the addition of vacuum pumps.
– Plus additional capability at 4 K for shields• This is sufficient cryogenics for all PD front end testing
– A lot of available space• There is a potential for a long beam line if we want to test more of the
PD front end.
• Disadvantages– The building is at grade, so a lot of shielding is needed for high-
power beam (i.e. the PI+ ILC beam).– Not enough cryo to run PD and 2 K tests simultaneously

The New Muon Lab
• Advantages– A great space
• Long enough for PI plus two ILC modules• Big enough for all necessary equipment and more
– Space for CW and vertical-dewar tests, for example• Floor is 20’ below grade, making radiation shielding easier• Plenty of unencumbered space around the building for additions
– A new big refrigerator and building– Building a tunnel extension is straightforward– It’s ~ 2 km to the site boundary
• Disadvantages– Must move the Chicago Cyclotron magnet now– A tunnel extension is necessary have more than two ILC modules– Requires a temporary cryogenic system to keep to the schedule
May 11, 2005P. Limon --- Accelerator Advisory Committee 17Fermilab
Additions to the New Muon Lab
• Temporary cryogenics at NML; we have a plan• Moving the Chicago Cyclotron magnet
– Two commercial cost estimates are ~$300 K for rigging• Plus ~$200 K for road and wall removal (w/o contingency and G&A)• Plus ~12 person-months of Fermilab labor for coil removal and prep work
– CCM move should be done before anything is installed into NML• Building a tunnel extension at New Muon.
– A conceptual design and cost estimate are being worked on at FESS. A preliminary estimate is ~$1 million for a 50 m extension (incl. cont + G&A)
– No major modifications to the building structure are required– Tunnel can be built later; not needed until there are more than two ILC
modules• Building the new refrigerator at New Muon
– Being studied: whether the SSC refrigerator stored at ANL will be useful in whole or part. Expect a report in early June; a decision in August.
– A detailed refrigerator specification is being developed

CONCLUSIONS• We are on track for an early start of cryogenic and RF tests
in the Meson Lab– We are on schedule to have Meson ready for equipment installation by
June 13. The goal is to test a single-cavity module in early FY2006.– Need one week of beam off (Scheduled to start June 6) to install
shielding in beamline tunnels. May need another week of beam off.• The Plan is feasible and satisfies all requirements
– Single modules are tested at Meson Lab and are not delayed– There is no delay in the startup of operations at New Muon Lab.
• There are good options for early temporary cryogenics– The cryogenics at Meson are adequate for all PD front end and single-
modules tests• The modifications to New Muon are slight• The risks are understood
– The major risk is not getting started aggressively
