CC Magnets
• 1st CC magnet– Cold mass at LBNL
• First physical (CMM) and electrical measurements complete;• Design of the cooling circuit finalized for Fermilab testing;• Vacuum potting prep underway;• Thermal stress analysis during cool-down complete;• PID (Piping and Instrumentation Diagram) in progress.
– Quench protection• Contract signed with MIT;• Preliminary analysis of QP indicated 4 sub-divisions may be adequate
(original design has 8);• Design of the stabilization of HTS and SC current and QP leads
underway at MIT.

CC Magnets• 1st CC magnet
– Testing preparation at Fermilab• FSU cryostat;• Testing location identified;• …
– SC wires (261 km) ready to be ordered – Review of the cryostat drawings nearly complete;– Modification/updating of the drawings in progress at LBNL
• Cryostat fabrication readiness review after next MICE Collaboration meeting (Feb. 8-11, 2012)
• Winding procedure review in China (Mar. - Apr. 2012)• Winding of the 2nd coil could start June 2012 or earlier if we
decide to mix two different SC wires

MICE RF Cavities• RF coupler design updated;• Additional welding of cavity support struts
complete;• Single cavity vessel fabrication complete and expect
to arrive Fermilab this month;• Fabrication of six tuner arms in progress at
Fermilab;• Discussions on potential assistance from LBNL on
MICE LLRF control initiated.
