Layout of MICE hallDecay solenoid

Downstream beamline

Linde refrigerator

4

DSA (Decay Solenoid Area)

Large section of North wall now removed to allow:-•Survey and set-up of D2•Installation of girder boxes on Q35 baseplate•Test of extension rail frame over D2 support•Installation of Decay Solenoid (after test), trolley and stand.•Connection of transfer line to Decay Solenoid.

5

DSA (Decay Solenoid Area)

Roof design underway – plan to have removable mesh panels which can support borated polythene (if needed).Idea to leave area around decay solenoid turret open (confined space regs.) and provide escape route without allowing unauthorised access.Lots of work on cable, water, services.

6

Delay Solenoid

Major work in repairing MLI (Matt Hills and Liverpool). Cold mass roughly aligned. Solenoid moved to trolley, on rails. Rail system sits on temporary false floor.

7

Linde cryogenics

Problems with compressor / refrigerator (see talk from Mike Courthold). We can still go ahead with test of decay solenoid. We would like to run a 50m network cable.Nick Moore (who is installing the Network for the MICE Hall, will need the two switches which Jean-Sebastian has promised to provide.Are they already at RAL or do they need to be shipped?

Q35 Refurbishment & Installation

•First 4 magnets essentially finished. Tests in R6 going well (2? complete plus a “known good spare” identified). •All girder box supports complete and assembled. One mounted on upstream baseplate, 2 on downstream plate. Both baseplates aligned, levelled, grouted and re-painted.

9

MICE Local Control Room (MLCR)

•All rack bases installed •First 7 racks installed (including Network and PPS racks.•Of the remaining 4 rack positions, we will only ask DL to supply 2 at the moment. (Target rack plus an ‘overflow’ target rack that will probably have some space available). •Cable trays installed from MICE Hall, through the wall and along the floor of the MLCR.•Hope to have network available within ‘days’. Will probably be just a single cable into the MICE Hall initially (for Decay Solenoid tests).•Hopefully we will trial a wireless network (no guarantees that it will work).

Visitors coming to RAL to work on MICE- Visitors/contractors should complete a "RAL Pass Application - Non STFC Personnel" form. These forms can be obtained from the ISIS Users office. (or ask Richard or Andy to e-mail you a .pdf – it seems you can’t download it from the STFC site!)

- The form should then be signed by a RAL member of staff (Richard Apsimon/Andy Nichols). An "end date" for when the pass will expire must be entered on the form.

- Once signed, the form should then be taken back to the ISIS User's office where it will be entered onto the Staff Database.

- The following day, once the Staff database updates, the Pass Office will have all the relevant information with which to issue a Pass. Visitors/Contractors should then go to the Pass Office to obtain their pass.

Also, please note:

1. They have to register at the USER Office on their first day.

2. Include on the pass form if you needed to have i) a computer access and ii) RAL Outlook access.

3. They will be scheduled to attend a 1 1/2 hour Health and Safety Training Course.

Other issues•Everything we are doing is focused on the Xmas shutdown schedule and the target of 20th Jan.•To meet this, delays are creeping in to other work which is not crucial for January but which is very important to the success of MICE. e.g.

– Magnetic shield wall design and installation.• South wall designed and structural calculations complete.• Magnetic steel specification complete and designs done (South wall).• North wall drawn and designs with Opus for structural design. (DSA roof may

need to take precedence)– False floor and plinth design– Correction of the vacuum box in D1– Vent pipes and excavation work for Hydrogen system

•Linde have been severely hampered by the lack of network connectivity.•The termination of the network in the MLCR and 'at the other end' can/will start today. To do this, they need temporary mains power into the MLCR. This should not be a problem. •For the solenoid cool down, perhaps we can run a 50m network cable?•Wireless in the Hall may be noisy?

•Finances are too tight. We probably can’t afford anything else!
