  1. Integration of the Spectrometer Solenoid Magnets Steve Virostek Lawrence Berkeley National Lab MICE Collaboration Meeting – CM20 February 11, 2008

  2. Integration and Installation Topics • Support structure interfaces • Module joint seal and load transmission • Subcomponent interfaces • Tracker-to-warm bore, radiation shutter, patch panel, diffuser, iron shield • Power req’ts, cabling & hose connections • Instrumentation and controls Steve Virostek - Lawrence Berkeley National Lab

  3. Translating Platform Steve Virostek - Lawrence Berkeley National Lab

  4. Progress Update • Fab of first magnet support stand is complete • Six mounting pads added to design • Possible issue with clearance around holes • Features added to suppt allow lifting by slinging • Vendor also adding welded lifting rings to vessel • Feature for mounting diffuser added to magnet • Integrated iron shield/TOF shield design done • Magnet interface remains unchanged • Parts to be procured soon Steve Virostek - Lawrence Berkeley National Lab

  5. Progress Update (cont’d) • Helium-to-vacuum window design not done • Preliminary plan was to use AFC style window • Mounting holes not included in magnet spec • Final design of bellows spool under way • Bellows design & price quote obtained from Hyspan • Spool to connect two spectrometer solenoids being designed at RAL (two bellows spools also req’d) • Instrumentation readouts to be ordered soon • Most instrumentation only needed during initial tests Steve Virostek - Lawrence Berkeley National Lab

  6. Module Mounting Provision Six mounting plates added to the support stand base for installation on rails Steve Virostek - Lawrence Berkeley National Lab

  7. Module Lifting Provision Four cutouts added to the support stand side walls for lifting straps Open issues: Will a lifting fixture be required? Can we lift w/iron shield in place? Steve Virostek - Lawrence Berkeley National Lab

  8. Support Stand Modifications Steve Virostek - Lawrence Berkeley National Lab

  9. Iron Shield and TOF Cage Steve Virostek - Lawrence Berkeley National Lab

  10. Spectrometer Solenoid-AFC Module Joint Spectrometer solenoid flange AFC flange 36 bolts on a 1470 mm dia 56 mm Metal seal groove O-ring groove 1372 mm ID bellows Steve Virostek - Lawrence Berkeley National Lab

  11. Magnet Utility Requirements • Cryomech Model PT-415 cryocoolers (4 or 6 each total) • 50 Hz AC: 10.5 kW @ 380/420 V, 3 phase • Cooling: minimum 3 gpm of water @ 80ºF max • 300 A Power Supplies – American Magnetics (3 ea total) • 50-60 Hz AC: 3.5 kW @ 208 V, 3, forced air cooled, rack mnt. • 60 A Power Supplies – Lake Shore Cryotronics (4 ea tot.) • 50-60 Hz AC: 0.3 kW @ 208 V, 3, forced air cooled, rack mnt. • Vacuum: 10-3 torr @ startup thru a 25 mm flanged port • Liquid cryogens: 600 liters LN2, 1000 liters LHe (x2) • Instrumentation monitoring requirements • Various voltages, temperature, He level, heaters, pressure, vac.
