The first shipment of legs for the partial return yoke arrived on Tuesday (17Feb15). The legs were received in R9 and prepared for installation; nuts to hold the jacking bolts were welded into the feet of the first set of legs which were then moved to the Hall on Friday and fitted in position. Welding of the nuts on the second set of legs took place today so that they can be fitted into position in the Hall tomorrow. Once the legs are position coarse alignment will be performed before the geometer is called in to make the final alignment.
The steady progress on completing the wiring in Rack Room 2 continues.
On the operations side, many of the issues noted in the first mock data run have been addressed. Regular operations meetings have begun; Steve Boyd is setting up a mailing list, the sister of the MICE Hall list, to disseminate the information from these meetings.
The near future:¶
MICE Hall: Priority for work in the Hall remains the completion of the installation and alignment of the PRY legs on the North Side of the channel. The Hall team is gradually being augmented; this week Kevin Ladhams from Imperial will join the team. Once the preparation for the alignment of the PRY legs is complete, work will restart on the installation of support of cryogenic services and electrical services while the alignment itself is carried out.
08Mar15: The operations team are preparing for running on the 08Mar15. The schedule for this run remains as in the previous status report. Detailed plans will be circulated by Steve Boyd and Pierrick Hanlet (MOM) in the near future.
Weekend operations from 21Mar15: Weekend operations will start on the weekend of the 21Mar15. The shift sign-up for the 08Mar15 run and the weekend runs is live in CHEESE; you are urged to volunteer as soon as possible.
Following the discussions at CM41 another pass is being made through the commissioning and running plans for Step IV that we laid last autumn. The assumptions made (trigger rates etc) will be revisited and the time estimates checked. Progress on the review of the commissioning and operations plans will be presented at the next VC. With this re-analysis we will be able to revisit the Step IV shift allocation. As part of this re-analysis a weekly planned maintenance day is being considered.
