Cooldown completed Thursday 16 April, temperature ~4.5K
Fri 17-20 April, quench detector (num 5) still not working.
One vacuum pump remains off (tripped 18 April)
Mon 20 April, ramped up to 400 A and Decay Solenoid coils go
superconducting (first indication Multi-Layer Insulation working)
— Between 21-23 April:
o Quench Detector (QD) problem diagnosed to broken wire within QD
chassis
o 2A fuse associated with QD external relay chain blew and replaced
with 5A fuse (need to restore original fuse tolerance)
— Fri 24 April: Decay Solenoid powered up in stages to 900 A, then brought
down to 870 A (5T B-field), where it remained for 1 hour before
powering down once more.
— Further tests to be carried out this week. Meeting 28 April to decide
procedure for signing off decay solenoid for standard operations

Commissioning Needs
• Working target – Stands..
— one in R78 for demo
— one in ISIS for data
• Detectors –
— Tracker cryostats (Alan Bross at RAL last week)
o All pressure release valves tested
o Installed emergency shutoff valves on cryostats – all 4 installed and working
o Installed exhaust filter
o CRYO 3 & 4 now working stably and at low temp (~6K)
— CKOV
o Need network connection and power in the DSA – info from new temp and
humidity sensors not yet logged
o Spare HV power supply that died still not replaced
• Air conditioning
— Ducting for A/C venting well underway towards 6 holes in West Wall
— A/C unit placed on South Wall mezzanine
• MICE-EB decided to delay removing synchrotron shielding until August
shut-down. Upstream Decay Solenoid shielding reinstated

Issues
• Documentation inventory/overhaul - ongoing
— Instructions for shifters – old documentation needs updating
— Safety – need all relevant documents in one obvious place
• Computing

Need network connections to progress in Hall
Still cannot print on OKI printer in R76
Wireless in R76 still not installed but network people aware of problem
Need Windows PC in MLCR – still pending
Need connection to GRID from MLCR – pending
• Need beamline magnets on to test alarm handler
— Water will be restored to magnets –this week?
