Minutes * *Present* : Yordan, Paul H, Paul S, Mike C, Vicky B, Josef F, Colin W, Andy N, Craig M, Steve B, Pierrick H, Ken L * *Actions from last meeting* ** Generate appropriate table to store absorber pressure and material information (Janusz) : (almost done) ** DS readback current requires calibration (DL) : stands until close to powerup ** Issues arising from last data taking run need to be identified and actioned (Boyd) : Stands ** Get an estimate for how long it takes to wire in the chiller in (Andy) : Done - about 3-4 days. * DC report ** Focus coil won't go back in since the bellows have been switched around and now the screw hole tolerances no longer match. ** When John gets back from holiday the FC will be pulled out and the bellows swapped ** Daresbury work went well. An ongoing work plan is shown below ** US team came out with a program of work, some of which can be done but because the racks are not fully commissioned the full program of work can't be completed. ** This week HPC have started to work on the compressor for the DS. They are concerned about the temperature of the air end - it's too hot to touch. They plan to replace this in August. Colin:Can we just buy a new one rather than replace in August? Mike: What we get is effectively new but we should put an order in. Colin:we should do a comprehensive job on fixing the compressor so need to understand this issue. *** *Action Item*: Vicky will investigate the state of the refurbished air end to see what we get for our money. ** Daresbury will allow the US to run into a short this week. ** Alan B : the 20 psi main relief valve for SSU needs replacing. Alan has a replacement but it needs installation. This can happen when John is back next week. * Work plan for the next week : http://micewww.pp.rl.ac.uk/attachments/6180/2016-05-02-Workplan.pdf http://micewww.pp.rl.ac.uk/attachments/6180/2016-05-03-MICE-Hall-Plan.xlsx ** Henry: Water plan goes into period when the DSA is closed. If we turn the water back on we may be in a situation where the water pipes to the conventional magnets could blow. If the DSA is closed we can't get to it. Colin: Good point. Henry: We also need the full ISIS running schedule spreadsheet. Colin:I've got something - I'll send it to you. ** *Action Item*: Colin will put the ISIS dates for run-ups and machine work into his schedules to better reflect available access time. * QP/QD work ** Discussed during the DC report * Water system work plan : Colin:There is no day-by-day plan, but the plan for what is being done is understood. The plan is not going to (ha) plan due to delays in getting an external contractor. ** *Action Item*: We will make some form of water system schedule available (Colin) * Bellows installation and FC cooldown : Bellows discussed during DC report. We plan to pump the FC down ASAP and then, if happy, start the cooldown. * Tracker hall probe installation: Will start tomorrow. Craig and Melissa have a plan which will get the losses down to an acceptable level. This will only take a day or so. * AOB ** Prescaled trigger discussion: Yordan is organising a phone meeting to develop the prescaled trigger. For those interested there is a Doodle poll for this meeting. ** Henry: Still looking for people to train as BLOCs. BLOC training will happen in June. An invitation will be given at the VC. ** Henry: Water detection in the trench? Pierrick: we have water detection in the trench but it's in the gutter and so shows water detection all the time. We need to come up with a proper plan. *** *Action Item*: Henry, Craig, Paul and Pierrick to look into optimising this for once and for all. ** Henry: Can Paul lower the target frame and check that the laser light levels haven't changed. Paul: Yes.
