  • Macwaters - Report on status of FC psu repair (stands)
    • TH chasing Thurlby-Thandar. Cause of failure is that there may still have been a few mA in the circuit when it was powered off with contactors still closed

  • Hall Manager - water system change-over procedure (stands)
  • EOverton - Status of miceraid5 disk cleanup (stands)
  • MCourthold - show JBoehm how to use the Picologger for quench data. Craig can help. (on hold)

    • JC has shown JB how to use the Picologger which has been re-connected to the FC quench system
  • JBoehm & Macwaters - get the West Wall compressors correctly labelled, as various have been re-purposed (stands) Use the number before the # symbol - this is expected to agree with the Alarm Handler
  • CWhyte to contact DL to clarify their Hall Task List items

• New Actions
  • CWhyte to request survey of TOF1

• DC Update:
  Activities mainly LH2 work and Tracker cryo saga: seems to be a lot of air getting in. Lots of RGA scans
  • Tracker Issue
    Cryostat 2: followed the official procedure for warm-up and cool-down. Have lost 12% of channels on one cassette and 27% on the other. Thought to be due to aging seals.
    Pump/purged Cryo 3 yesterday, today see 13% N2. Think there's an air leak in. Try a pump/purge excluding the cassette space to see if the leak is at the cassette or the plumbing.
    Also had a "Low Lid Temperature" alarm and a backing pump fail on Cryo 2 today.
  • LH2 Update
    The LH2 Quench test with Neon will be in June (no CC magnets this cycle).
    Hope to be ready to start cooling today - final vacuum and leak-checking - and start cool-down tomorrow. Still need to fix the quench line before the real LH2. FC will stay in position this cycle.

• MOM Update
  Expert start-up yesterday: The wrong absorber got written into the CDB, else OK (note have no Trackers).
  AKurup wants to try new ALH tonight.
  Beambump tune today: search Hall at 4 - with LH2 and Tracker work, better to postpone till tomorrow. We need ISIS BLM info to be getting into EPICS.
  Daily Run Meetings will be (in ISIS coffee lounge) at 2 p.m. so that we know how the Hall work is going that day.
  Next tranche of Shifter training will be on Monday.

• AOB
  TOF1 has been replaced in position and the plastic sheet removed: it will need a survey.
