MTA 201-MHz Program Overview(Surface treatment, NF channel, MICE)
• 201-MHz MICE prototype cavity with SRF-like surface treatment (EP, HP rinse)– Conditioned to design gradient quickly– Demonstrated operation with curved Be windows– Somewhat reduced performance in fringe field of
solenoid– No surface damage seen on cavity interior– Some evidence for sparking in the coupler
• New design has been implemented– Radiation output measured (MICE detector
backgrounds)• Future
– Install/operate single-cavity vessel– Large diameter magnet (“coupling coil”) needed
for field configuration closer to MICE/cooling channel

201-MHz Single-Cavity Module
February 15, 2013
• MICE cavity in vacuum vessel for MTA test
• Components– 1st MICE cavity EP’ed
and now at Fermilab– Be windows ready– Tuner forks built– Ready for fabrication of
new couplers

201-MHz Single-Cavity Module
• Assembly/integration– Cavity and vessel at Lab-6– Clean room prepared– Plan in place for handling
and transport (R. Schultz, J. Volk)– Assembly fixture designed (A. DeMello)– Tuner control bench tested (P. Hanlet)
• Expect operation Summer 2013– beam test also under consideration
• Ultimately will be tested with the first Coupling Coil Magnet– Requires 6-month MTA shutdown

Current configuration
• Original prototype cavity still in the hall• was lifted onto platform during long
shutdown with shield wall out• using temporary forklift
• No vacuum vessel, air outside• end-plates for support
• Couplers already removed• one cut up for inspection
• To be lifted off platform• with new gantry crane
• span limited by entry maze• and rolled out through labyrinth on
casters• Rails will be reused for new module• Be windows will be transferred to new
cavity

Module Transport
• Will bring into MTA hall through labyrinth• Vessel with heavily ribbed doors too wide for
labyrinth– Will remove and roll in doors separately– Put on thin cover plate to keep module interior clean
• Module on stand too tall for clean room and labyrinth– New “transport” stand is 10” shorter
• Tight fit – checked with laser scan data

Lab 6 Clean Room
• Once doors removed & transport stand installed
• Cavity installation – Vertical– In Lab 6 clean room – Class 100– Insertion picture shown in clean room is old design– New design (A. DeMello) hot off the press– All mechanical assembly and RF testing in clean
room

Cavity handling
• Detailed procedure available from LBNL

Tuner installation
Initial concept – horizontal layout
February 15, 2013
Y. Torun | MICE cm35 20
Cavity installation
Vertical layout selected• Smaller footprint better suited
to available clean room space• Similar to MICE RFCC• Simplified (one-sided)

Other issues• Couplers
• preferable to test/condition before installation on cavity• couplers for prototype were conditioned at SNS on custom stand
• looking into locating leftover parts to it back together (R. Rimmer)• or designing a new stand
• Diagnostics• will build top plate with RF and vacuum pickups• acoustic sensors under test may be useful (P. Lane, P. Snopok)
• RF controls• plan in place to upgrade Linac 201-MHz station (R. Pasquinelli)

Outlook
• On track for results from operation of single-cavity module at MTA by cm37
• tight schedule and lots of work to do• resource availability critical
• Installation will provide valuable experience for MICE RFCC module assembly
• There may be an opportunity to test MICE RF phase measurement concept
