Slide 2

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 February 15, 2013 Y. Torun | MICE cm352

201-MHz Single-Cavity Module February 15, 2013 Y. Torun | MICE cm353 MICE cavity in vacuum vessel for MTA test Components 1 st MICE cavity EPed and now at Fermilab Be windows ready Tuner forks built Ready for fabrication of new couplers

Slide 4

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 February 15, 2013 Y. Torun | MICE cm354

Slide 5

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 February 15, 2013 Y. Torun | MICE cm355

Slide 10

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 February 15, 2013 Y.

Slide 27

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) February 15, 2013 Y. Torun | MICE cm3527

Slide 28

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 February 15, 2013 Y.
