<-- Summer 2021 RC meetings

Thursday, October 21

  1. Last 24h:
  2. Remaining issues:
    • Tagger hodoscope time shifts
    • communication with accel. w.r.t. tagger magnet - Paul Vasilauskis (Ops group leader): "I am putting out to my staff to contact the hall if they do need to touch the magnet and am looking into adding wording to the magnet screens"
    • BCAL noise at 10 o'clock
    • Bleedthrough
  3. Plan:
    • When the beam is back continue production at 200nA after the usual checks (radiation levels & harp scans)
    • Continue running with the solenoid on & target full until Friday or later
    • Pass change for A&B Saturday morning (A->4 pass)
    • Expect downtime Monday morning for VIP tour, start time TBC probably ~7am.
    • Ops will need another maintenance day before the energy change
