Integration
• Ties together– Resources– Design Activities– Oversight
paul drumm; September ‘05; FAC 10
Beam Line
• Beam Line– Target on the ISIS synchrotron – Optics: capture; decay; matched beam into the
MICE channel • Beam elements from ISIS• New power supplies
• Decay solenoid from PSI• cryogenic system expensive
paul drumm; September ‘05; FAC 11

Infrastructure
• Shielding• Electricity• Water• Alignment• RF Power Systems*
– Reuse of equipment (ex LBNL ex CERN)
• Hydrogen delivery system*– Critical safety issue
* Funded for prototyping to reduce downstream schedule risks
paul drumm; September ‘05; FAC 14
Cooling Channel:AFC
• SC Coils surrounding liquid hydrogen cell– Complex engineering
task– Critical safety issue– 20 l each absorber– Explosive : 17% - 56%– Flammable : 4% - 75%– Ignition: 20mJ in air– Gas. Density: 6% of air– Liq. Density: 7% of
water– Expansion ratio 800:1– Particular problem of
pumping– Oxygen plates out on
cold surfaces & cannot be detected

Safety Issues
• General engineering issues– Working at height– Heavy objects– Confined spaces
• More specific risks– Cryogenic fluids– High Voltage– Magnetic fields – RF fields & Xrays– Ionising & non-ionising radiation– Liquid hydrogen
• Uniform approach safety first• Processes & tools in place• RAL Confidence in MICE is important for success
paul drumm; September ‘05; FAC 24
Critical Path - Significant Milestones
• Delivery of Decay Solenoid Cryogenics
• ISIS Shutdown 2006/7
• Completion of beam line
• Delivery of completed tracker detector
• Delivery of PID instrumentation
• Delivery of 1st spectrometer solenoid
paul drumm; September ‘05; FAC 25
Risk
• Delivery of items in phase 1– Cost overrun (always a risk)– Schedule slippage (¨)
• Still dependent on successful funding bids– INFN particularly– Be, Nl, CH
• Contingency plan:– Re-evaluate minimum needs to characterise the beam– Re-alignment of activities to meet these needs
paul drumm; September ‘05; FAC 26
Risk
• Delivery of items in phase 2– Contingent on successful delivery of phase 1– Same cost & schedule risks
• US delivery cash limited– Cavities, coupling coils
• Again dependent on as yet unfunded bids (e.g.)– UK: absorbers, cavity– CH: coupling coil
