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
  • 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.
