1 Engineering Session Summary Andy Nichols, STFC MICE Collaboration Meeting, RAL, June 2009

Engineering Electrical: –Cooler compressors – ensure access for maintenance –Hall PPS completion now October 2009 –Open question still for AFC/RFCC dump circuits –Ditto control station rack –Are racks and doors secure in magnetic field? –Are components in rack susceptible to high fields from S/C magnets? –Network requirements for step II to be defined –Ditto vac system/pumping cart controls –Electrical drawings and documentation to be defined in PDF –Proposed control station for spectrometers and cooling channel – concise technical spec to be submitted to TB 2

Engineering Electrical: –2MVA substation upgrade is a clearly a worry – design is done, but long lead time + funding uncertainty –Essential for Step III – Andy to remind CPMB (again) –Huge progress over the last year, despite cut to UK manpower –Many thanks to the Daresbury electrical and controls group! 3

Engineering Mechanical & integration: –Steps I & II installation defined in detail and agreed –New requirement to keep S/C magnets cold while ‘parked’ and while moving –Not desirable to ‘wind up’ cooler compressor hoses –Third downstream Virostek disc certainly required –Not a major difficulty – seems sensible to make in UK –Wing Lau will broaden his integration remit to include PID –Wing to also take responsibility for component integration –Better control of interfaces required (better use to be made of TB) –That ball is in my court! 4

Engineering Welcome to Franck Cadoux and his colleagues –Working on the EMR –Useful offline discussion this week –Visited MICE hall, understand cable routes, space envelopes and CAD interchange with RAL 5
