29. paul drumm; September ‘05; FAC 29 Risk Delivery of items in phase 1 –Cost overrun (always a risk) –Old equipment: decay solenoid – fragile – new cryo-system Large aperture quads: refurbishment cost R&D: power systems; hydrogen storage –High rates could impact on run time –Schedule slippage ( ¨ ) Still dependent on successful funding bids –INFN particularly, –Belgium –Risk Management plan: »Re-alignment of activities to meet these needs

30. paul drumm; September ‘05; FAC 30 Risk Delivery of items in phase 2 –Same general comments - cost & schedule risks US delivery cash limited –2 nd solenoid, Cavities – R&D, –coupling coils, absorber windows Japan –Absorbers: low risk Again dependent on bids in preparation: –UK: focus coil module, cavity, RF power (tube issue), –MICE-UK phase 2 contingent on successful delivery of iMICE phase 1 –CH: coupling coil

31. paul drumm; September ‘05; FAC 31 Summary Technical Progress is good towards phase 1 –Technical Risks to phase 1 are modest –Beam line will be complete spring 2007 –Tracker performance is to specification & on schedule –1 st spectrometer to characterise beam in late 2007 Plans in place for phase 2 –Need resources to accelerate build schedule
