Topic Summary

• Module shipping logistics
• Delivery to RAL
• Module re-assembly at RAL
• Installation in MICE Hall
• Module interfaces
• Flanges and seals
• Base mounting
• RF feeds
• Utility requirements

Module Shipping Logistics

• Cavities, couplers, coolers pumps removed
• Vacuum vessel/magnet mounted on short stand
• Short stand also used during assembly
• Coupling coil magnet shipped warm without
  cryocoolers in place
• Cavities and couplers will be packaged separately
  to prevent damage
• Vacuum vessel and cavities are to be blanked off
  and backfilled with N2

RFCC Module Shipping Configuration
Cryocoolers removed Cavities removed
Couplers removed Vacuum pumps removed

• Module short stand used for
• Initial module assembly
• Shipping to RAL
• Moving into MICE Hall

5
Delivery to RAL

• Module arrives on short stand without cavities,
  coolers or couplers installed
• MICE Hall door height 3360 mm
• Module height on short stand 2844 mm
• Height is without cryocoolers installed
• Roller dollies w/forklift used to move into hall

100 mm tall Roller dollies

Re-assembly of Module at RAL

• Unpack cavities, couplers, coolers, pumps
• Operating stand placed on lateral tracks
• Vacuum vessel/coupling coil is loaded onto
  operating stand for final assembly
• Portable clean room erected around module
• Cavities are installed using special lift fixture
• Couplers and tuner actuators are installed after
  cavity is aligned and supported w/struts
• Vacuum pumps are added to complete module
• Final alignment performed before translation

Installation in MICE Hall

• Module assembled on lateral tracks
• Module aligned and shimmed to correct height
• Bellows on either end of module are pulled back
  into open position and O-ring in place
• Moved into position w/rails for final alignment
• Bellows are released and flanges are sealed
• Bellows are locked out using bridging bolts
• RF and utilities are connected to module

24
Module Flange Connection
End flange O-ring seal
Formed bellows
Flange through holes
25
Flanges and Seals

• Flanges designed to mate with AFC module
• AFC flanges are flat w/no grooves or bellows
• RFCC modules have bellows and O-ring grooves on
  flanges at either end
• Bellows have gt1 cm of total travel
• Bellows are locked out after installation to
  provide a means of transmitting forces between
  modules

26
RFCC Bellows and Flange
Bellows pull back bolts
Elastomer or Helicoflex all-metal O-ring
Clamping bolts

Module Joint Sealing Issues

• MICE module joints may need somewhat frequent
  disassembly (reconfiguring, maintenance, repair)
• O-rings will provide the most reliable and cost
  effective (inexpensive and re-useable) solution
• O-rings are acceptable for use in MICE
  environment
• But, MICE should demonstrate all technologies for
  a future machine including the use of metal seals
• The O-ring groove is design to accept a
  Helicoflex all-metal O-ring for demonstration
  purposes

28
Module Base Mounting

• Module base connection to rails identical to that
  used on the Spectrometer Solenoid
• Six mounting plates are welded to the base of the
  module support stand
• Precise geometry and location of the mounting
  plates to be coordinated w/RAL during CM21
• All magnetic loads are carried to the floor
  through the mounting plates

29
Module Mounting Provision

• Six mounting plates to be welded to the support
  stand base for installation on rails
• Similar to spectrometer solenoid mounting scheme

30
Cavity RF Feeds

• Eight RF feeds/module use standard 4 RF coax
• Cooling water for loop is required (ltlt1 lpm each)
• Adapter on end of couplers isolates ceramic RF
  windows from forces during installation
• Location of coax interface w.r.t. module center
  TBD

RF feeds
31
Module Utility Requirements

• Cryomech Model PT-415 cryocoolers (2 or 4 each
  total)
• 50 Hz AC 10.5 kW _at_ 200/220 or 380/420 V, 3 phase
• Cooling minimum 12 lpm of water _at_ 80ºF max
• 300 A Power Supplies American Magnetics (2 ea
  total)
• 50-60 Hz AC 3.5 kW _at_ 208 V, 3?, forced air
  cooled, rack mnt.
• Vacuum 10-3 torr _at_ startup thru a 25 mm flanged
  port
• Cavity cooling water 8 lpm/per cavity
• Power for periodic getter pump regeneration (TBD)
• Liquid cryogens LN2 and LHe for cooldown (qty
  TBD)
• Instrumentation monitoring requirements
• Various voltages, temperature, He level, heaters,
  pressure, vac.

32

  removed and packaged separately
• Short shipping stand provides comfortable
  clearance through MICE Hall door
• Module re-assembly at RAL will require a portable
  clean room
• Installation in MICE Hall
• Module interfaces to be finalized soon
• Flanges and seals, base mounting, RF feeds
• Utility requirements have been established
