Integration
• Ties together– Resources– Design Activities– Oversight
paul drumm; September ‘05; FAC 11
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

– Reuse of equipment (ex LBNL ex CERN)
• Hydrogen delivery system*– Critical safety issue
* Funded for prototyping to reduce downstream schedule risks

Instrumentation: Particle Identification
• Conventional particle detection applied to accelerator diagnostics– Particle identification– Impure beam – protons, , , (e from decay)
• Time-of-flight• Cherenkov• Calorimeter
– Momentum & emittance measurement• Spectrometer: Tracking in a magnetic field
paul drumm; September ‘05; FAC 22
Instrumentation: Spectrometer Solenoid
• Critical path item
• US responsibility– Additional over proposal– Cash flow limited

Safety Issues
• General engineering issues– Working at height– Heavy objects– Confined spaces
• More specific issues– 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 26
Cooling Channel: AFC
• Hydrogen Safety Issues– 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

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 28
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 29
Risk
• Delivery of items in phase 2– Contingent on successful delivery of phase 1– Same cost & schedule risks
• US delivery cash limited– 2nd solenoid Cavities, coupling coils, absorber windows
• Japan– Low risk to absorbers
• Again dependent on as yet unfunded bids (e.g.)– UK: focus coil module, cavity, RF power– CH: coupling coil
paul drumm; September ‘05; FAC 30
Summary
• Technical Progress is good– Beam line should be complete spring 2007– Tracker progress & performance is to spec.– Beam characterisation depends on solenoid
• Technical Risks to phase 1 are modest• Resource limited Risks
– Solenoid schedule– Full set of PID detectors
• Schedule risks to phase 2– Resource limited delivery schedule– and Subject to funding bids
