  1. MICE Absorber and Focus Coil (AFC) Design Description MICE Hydrogen System Review 4th October 2011 Tom Bradshaw John Cobb Wing Lau Matt Hills Elwyn Baynham Mike Courthold Victoria Bayliss

  2. Introduction MICE Absorber and Focus Coil Magnet • Design of intent made by Oxford Nuclear Physics and RAL Cryogenics and Magnetics Group • Has two coils that can operate in solenoid or “flip” mode • Part of the MICE Lattice

  3. MICE Superconducting Solenoid Configuration MICE Lattice Spectrometer Solenoid Coupling Coil Absorber and Focus Coil Coupling Coil Absorber and Focus Coil Absorber and Focus Coil Spectrometer Solenoid These are large magnets and design is complicated by the interaction (forces) from the rest of the MICE lattice in the various stages of construction.

  4. Overall Views

  5. General View • Features • Separate space for hydrogen system • Safety Windows • Dump for any spills to limit boil off • Warm bore so cryogenics are not coupled • Hydrogen volume 22 litres • Should be able to test with Helium at 4K

  6. Detailed View • Windows are mounted off RT interface – see thermal model later • Space for change in pipe dimension close to magnet • Large “bucket” at base to contain any rupture

  7. Recent Progress and Status Winding of AFC 1

  8. Recent Progress and Status Winding of AFC 2
