1. MICE Target Schedule Chris Booth Sheffield 12 th June 2006

2. Chris BoothUniversity of Sheffield 2 Key Dates Assembly test R76 (RAL): 24 th -28 th April (past!) Mechanical test R76: 17 th -21 st July Mechanical & Electrical test R76: September Installation & Run in ISIS: Oct. – Nov. Installation for MICE: Summer ‘07

3. Chris BoothUniversity of Sheffield 3 To date: Low power tests (in air) in Sheffield –Demonstrated principles of control & drive –Demonstrated optical readout –Cooling, noise, reliability issues April assembly test & review –Redesign shuttle shaft –Redesign optical window enclosure, fibre alignment system, … –Checks on flanges, indium seals, etc

8. Chris BoothUniversity of Sheffield 8 September to October Fix any problems revealed in September! Continue to test & improve controls, interfaces, monitoring November test aims Operation with ISIS – interlocks, synchronisation Run at ISIS startup at 50 Hz/64 or 50 Hz/128 (lower activation, reduced cooling problems, …) Probably only run ~1 shift Measure beam halo profile – determine required insertion depth End of test: Raise above gate valve & close –Maybe run in that position at intervals during ISIS run?

9. Chris BoothUniversity of Sheffield 9 Beyond November Optimisation of stator cooling –Alternative to potting? –Closer cooling elements (eddy currents?) –Multiple coil banks Optimisation of acceleration –Magnet dimensions? –Shaft design (reduce mass) –Optimisation of control (current timing etc) Development of interlocks –Temperature, ISIS beam loss, … Development of monitoring –Temperature –Target profile –Links with MICE monitoring (EPICS) Development of control –Dynamic feedback from monitoring?
