MICE Spectrometer Solenoid Fabrication Update and Schedule StatusPage 10 Steve Virostek -- Lawrence Berkeley National Laboratory -- January 14, 2009 Magnet CMM Measurement Portable CMM will be used to align cold mass to end flange and set height Tooling balls will also be added to vessel and fiducialized to cold mass

11. MICE Spectrometer Solenoid Fabrication Update and Schedule StatusPage 11 Steve Virostek -- Lawrence Berkeley National Laboratory -- January 14, 2009 First Magnet Partially Disassembled

12. MICE Spectrometer Solenoid Fabrication Update and Schedule StatusPage 12 Steve Virostek -- Lawrence Berkeley National Laboratory -- January 14, 2009 The plan to move forward involves completing and testing Magnet #2 first (with all modifications) Several technical issues as well as negotiation with the vendor on change costs has delayed completion The current goal for completing the first unit (Magnet #2) including cooldown and test is the end of February Upon shipping of Magnet #2 (now first unit), Magnet #1 will be modified (reconfigure cooling, add vent line, LN reservoir, etc.) The reassembly and completion of Magnet #1 should follow by approximately two months Schedule
