  1. Overview and statusof international systems • Reminder of the principal deliverables • Status reports on: • Spectrometer solenoids • Radio Frequency Coupling Coils (RFCC) • RF Hardware • Electron-Muon Ranger (EMR) • Absorbers, liquid and solid • Partial return yoke • Conclusion • Acknowledgements to Steve Gourlay, Ruslan Asfandiayarov, Alan Bross, Ruben Carcagno, Steve Virostek, Alan DeMello, Steve Plate, Don Summers Andy Nichols, STFC, MICE OsC, 9-10-13

  2. Principal deliverables • EMR (Electron Muon Ranger) • UNIGE responsibility, delivered and installed and taking data successfully – constructional project now closed • SS (Spectrometer solenoids) • First magnet shipped to UK, presently in transit between Stanstead and RAL, second magnet has HTS lead problems • RFCC (Radio Frequency Coupling module) • Cryostat/cold mass parts now well advanced at LBNL • Leaks fixed on coil test facility • Winding of second coil started at Qi-Xian • RF Hardware • Major shipment of high value waveguides and other hardware received from UMISS, mainly for Step V/VI, but some for TIARA • Partial Return Yoke (PRY) • US contribution will be ‘above floor’ shielding assembly • Successful prelimianry design review • Aim for PRR in Dec.2013

  3. Principal deliverables • Liquid hydrogen absorber #1 • Required for Step IV • Installation tooling under construction • Design effort to understand open issue over window seals • Liquid hydrogen absorber vessel #2 • Required for MICE Step V • In manufacture at KEK, update required • LiH absorber • Nothing to report since last OsC

  4. Spectrometer solenoids • Main points to note: • First magnet flew to Stanstead on October 6th • Specialised handling required to get into R9 for tracker installation, but OK • Second magnet is complete, and has been pumped and cooled to well within spec. • But one HTS lead is high resistance and others may be suspect • So schedule under review in US • When they are changed, training and field mapping by CERN group can begin

  5. RFCC/Coupling magnets Progressing on four fronts: Cold mass test at FNAL – plan is to train coil before final assembly into magnet Vessel, cooling circuit and thermal shield fabrication at LBNL Coil winding at Qi-Huan Cavity production at LBNL – electro-polishing, completion of electro-mechanical tuners

  6. RFCC/Coupling magnets Progress with the CC vessel at LBNL

  7. RFCC/Coupling magnets Two major LBNL assembly tasks remain: Cooling circuit Thermal shield assembly Design is complete for both M/F underway Delivery to FNAL, February 2014 Final assembly and commissioning of all three magnets will be at FNAL

  8. CC coil test facility at FNAL Cold leak into vacuum space now fixed Cooling has resumed

  9. Solid absorbers • Procured through Y12: • – 1 – 20 cm diameter by 4 cm thick disk • • For thermal studies • – 1 - 45 cm diameter by 6.5 cm thick disk • – 2 half-wedges • • Disks complete • – Thermal measurements complete • • Meet spec. • • Wedges still in fab at Y12 • – Negotiating a cost to complete • CRADA is being negotiated between FNAL • And STFC for delivery • Process for acceptance and risk assessment cannot begin till we know • How it arrives

  10. Liquid and solid absorbers • Liquid absorber #1 has been unpacked • Absorber integration now defined as a UK work package • Installation tooling is made • Test vessel to understand indium window seals made, will be assembled and pressure/thermally cycled • Metrology of thin windows at LBNL a problem – possibility to help out at RAL • Injection of UK manpower very welcome in this and other areas

  11. Partial return yoke • MICE decision to adopt partial return yoke endorsed by external review on 24thSeptember, on the basis of eliminating a major technical risk • Conceptual design of yoke very mature • Review recommended physical separation of yoke and support structure at ground level • Yoke will be US responsibility • Support structure UK responsibility • Next step is a Production Readiness review (PRR) for both work packages, hopefully in December, 2013

  12. Conclusion Good news about spectrometer solenoid, hope that problems with second are minor Very good progress with RFCC – a major engineering effort, all problems now being understood, injection of manpower main breakthrough Some progress with VAT payment/recovery Still need to work out importing lithium hydride absorbers We have an acute storage problem at RAL! Magnets RF gear, etc Organisation of the project is now clearer Separation of the ‘experiment’ (MEMO) and the ‘project’ MIPO Has/will help to define boundaries and deliverables
