Henry Report (probably in absentia)

Target: there were instances of locals twiddling laser powers without consulting the Target Expert (Joe), or even making a clear eLog entry. NOT ACCEPTABLE.

Recording of laser powers in eLog is intermittent... list of items to note is in the checklist, and if people aren't even bothering to follow the checklist...

Water:

Sheesh. I refer to slide 9 of my CM talk from barely 3 weeks ago:

  • where's the the eLog information requested in the shifters’ “what to do when ... fails” list?
  • why did the magnet power supplies actually trip?
  • was the situation in the trench checked against the most recent "magnet walkthrough" checklist?

From a quick conversation with John, I think we are getting glitches in the PLC, see also eLog 4044.

Why were the requested snapshots of the stripchart not being made? The striptool was obviously running, given that David did manage to include the tail-end of the recovery in his first upload. Let's say I'm disappointed at the way this has been recorded.

Just to be clear, I am not going to be bounced into some sort of constant remote oversight of MICE running to make sure that everyone is doing what they should be; not as Beamline Co-ordinator and not as DC.

I have provided procedures and limits to allow safe and reliable running of the equipment, and a few checklists to reinforce some procedures. That running happens from the MLCR, and it's for MICE to arrange for it to happen [the procedures and checklists to be followed by those in the control room, or else the equipment will not be made available]. _(Note added later: I drafted this offline, uploaded in a hurry and somehow lost the tail of the last paragraph. Now included it in brackets.)

Resulting To-do (in next run-up week):
  • Trench Water PLC - Control Glitches (Rob Searle)
  • Water Pump Control GUI - Expert Password (C&M)
  • Trench Waterleak detection
    • unroll sensor to full length to cover new plant (John G/Henry)
    • fix sensor readout(?); add to alarm handler (C&M)
  • Striptools for Target and Cooling Water
    • finalise templates (Henry)
    • add to Tiered app launcher (Paolo)
