Progress Update
•Shipping skid for RFCC module developed
– Module axis is vertical during shipping
– Skid provides for rotation to horizontal in MICE hall
•RAL developing spectrometer solenoid lift beam
– Four lifting points are included on the magnets
– Load testing and certification is required
•Two module bellows spools received at RAL
– Bellows assemblies purchased from Hyspan
– Spools connect spectrometer solenoid to AFC module
– Apparent tolerance error being discussed w/vendor

Progress Update (cont’d)
•Still need a helium-to-vacuum window design
– Window separates vacuum space from tracker
volume in spectrometer solenoid bore
– Preliminary plan is to use AFC style window
– Good opportunity to add mounting holes now
•Several instrumentation readouts purchased
– Thermocouple and helium level readouts for the
spectrometer solenoid have been received by LBNL
– Similar readouts will be needed for RFCC module
– Most instrumentation only needed during initial tests

Shipping Logistics
•All modules to be forklifted on/off truck
•All magnet coils are shipped warm
•RFCC cavities, couplers, coolers & pumps removed
•Coupling coil integral with vacuum vessel
•RFCC axis vertical during shipping
•Concerns about shipping loads on coupling coil
•Special shipping skid has been developed
•Cavities, couplers packaged to prevent damage
•RF, Be windows left in place w/appropriate protection
•Vac vessel, cavities and couplers backfilled with N2

MICE Hall Access
•Forklift to be used for
unloading and moving
through hall door
•Door is tall and wide enough
for spectrometer solenoids
and RFCC modules
•No special equipment or
hardware is required

Re-assembly of RFCC Module at RAL
•Locate vacuum vessel/coupling coil on lateral tracks
•Erect portable clean room around module
•Unpack cavities, couplers, coolers, pumps
•Install six tuner assemblies on each cavity
•Insert cavities in vacuum vessel using special fixture
•Install couplers and tuner actuators after cavity is
aligned and supported by struts
•Install vacuum pumps to complete module
•Perform final alignment before translation

Module Base Mounting
•RFCC module and Spectrometer Solenoid base
connections to rails are similar
•Six mounting plates are welded to the base of
the module support stands
•Location of the mounting plates will be included
in an interface document (and later measured)
•Magnetic loads are carried to the floor through
the vacuum vessel/support stand/base mounts

Insertion into MICE Beamline
•Locate module on lateral tracks
•Align and shim module to correct height
•Pull back bellows on both module ends with
O-rings in place
•Translate module into position using rails
•Release bellows and connect flanges
•Lock out bellows using bridging bolts
•Connect utilities and instrumentation

End Flanges and Seals
•RFCC flanges mate with AFC module flanges
•AFC flanges have no O-ring grooves or bellows
•RFCC module flanges have bellows and O-ring
grooves at both ends
•Bellows are spec’d for >1 cm of total travel
•Module relative alignment is driven by
clearance in flange holes
•Bellows are locked out after installation to
allow transmission of forces between modules
