MICE PM Report
•Installations to date
•Future installation work
•Preparations for Phase Two
•Target status
MICE Video Conference, 22nd May, 2008
1
Installations to Date
Good progress over the last few months:
– Partial cold test of decay solenoid complete – liquid helium
demonstrated, compressor upgrade underway, full re-
commissioning by 16th June
– South shield wall supports well underway
– Pre-fabrication started for North support structure started
– First plates arrive 22nd May
– Concrete removal is done, structural weakness OK after all
– False floor design making progress – difficulty with quench
forces, but now solved
– Re-worked targets in progress, gate valve is open and
agreement to use current target some more – see later
– Conventional magnet installation is complete, Q7,8,9 are soak-
tested and signed off
Don’t intend to cover detail here – see MICO page and MICE News page

Future Installations
For completion of Phase One we need to:
– Install DSA roofing (ready to get quote)
• Installation in August now
– Build LH2 vent system (design in progress)
• But this is a concern – not sure the access/labour/ISIS shielding
problems are really solved
– Final sign off of decay solenoid (mid-June)
– Complete shield walls and install false floor (end July)
• First batch of shield plates arrive today
– Soak test and sign off all remaining conventional magnets (end
May)
– Hall and DSA PPS operational (end July)
• Delayed due to shortened May shutdown
– Complete electrical installation
• Steve Griffiths has itemised and understood all the tasks, aiming for
July/August, but some delays inevitable as other parts are late

Preparations for Phase Two
Step One in progress
– Sliding beamstop is designed and parts are being
ordered
– Long lead time means we miss May shutdown though
– Less sophisticated but cheaper static version will be used
(largely existing materials)
But the real concern is late delivery of TOFs, due to PM
problems
– Fall-back is to mount TOF0 outside the DSA, so we are
de-coupled from the DSA access during shutdowns

Preparations for Phase Two
•Detailed WBS and bottom-up cost estimates are
underway
•Various options to fit within likely funding profile
•RF Infrastructure project a significant part – previously
not on anyone’s list
•Mechanical integration drawings of each discrete MICE
step are being prepared – better able to assess the work
content that way.

Preparations for Phase Two
Status of major beamline components:
– Spectrometer solenoid
• Magnets being assembled by contractor, some minor assembly
problems, solenoid #1 arrives at RAL August, #2 October
– Diffuser
• Mechanical assembly almost complete at Oxford, test programme
agreed, physical integration trial with tracker at IC in July
– RFCC
• Final design review at Collaboration Meeting in June. Biggest
component we fit, must not under-estimate the integration
– KL & TOFs
• Ever closer to delivery, problems with PM tubes , but fingers crossed
KL itself and TOF & KL cables will be collected from Italy next week
– Solid spool piece and absorber
• In manufacture at UNIGE and FNAL, delivery in August, leak test at
RAL

Target status
Good progress with the target at both Sheffield and RAL
– All new mechanical bits for both new targets are at Sheffield
– New QA for actuator coil assembly and testing have been
implemented
– New coils (see above) are complete
– Both target assemblies should be ready by the end of May
– We miss the (now shortened) May shutdown to install the new
on-line target, but that’s OK:
• ISIS are happy for us to continue running the existing target in
machine physics shifts
• They have encouraged the target group not to hurry and to get a
realistic amount of testing done with the new targets
• On & Offline targets will now be installed during August shutdown
(4th-28th)
• The above is crucial to the success; it’s the trap we fell into last time
