ConclusionsConclusions MICE is proceeding towards Step IV Many achievements in last six months:

– New organisation with change of spokesperson– Mechanical and electrical integration being achieved– Hydrogen absorber inserted into FC– RF power in MICE Hall milestone achieved– Partial Return Yoke design achieved: out to tender– Target doubled rate and proton absorber completed– EMR delivered and running well– Spectrometer solenoid SS2 integrated with tracker 2

and SS1 completed at Wang NMR, ready for shipping Focus coil status, schedules and resources to be

shown by Roy Preece and Alan Grant in next talksMICE OsC Meeting, RAL, 24 April 2014
