Integration

• Ties together– Resources– Design Activities– Oversight


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


Location

MICE:1 Hz800 MeV~0.1 µA

ISIS:50 Hz800 MeV300 µA


MICE Hall


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


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

Module Integration: Module-to-module MICE to floor MICE to servicesAbstract: Forces Engineering Standards QA/QC

Interfaces & Integration


Instrumentation: Particle Identification

• Conventional particle detection applied to accelerator diagnostics– Particle identification– Impure beam – protons, , , e

• Time-of-flight• Cherenkov• Calorimeter

– Momentum & emittance measurement• Spectrometer: Tracking in a magnetic field


Instrumentation: Spectrometer Solenoid

• Critical path item

• US responsibility– Cash flow limited

Interfaces & Integration


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


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


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


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
