MCC whiteboard Meeting Bluejeans 660743227

Friday 29 October

  1. Last 24h:
    • Recorded XXM+ events
    • Change out of C02
    • RadCon replaced light bulb (really broken) in our rapid access beacon with an LED bulb
      • Access was necessary, but machine was actually down during that time
    • RCDB web interface was unreachable, shift crew contacted administrator and the service was restarted
    • HallC BCM calibration should not have affected us, but they use varying beam currents for that procedure, which may have changed bleedthrough during run 81620 (see [1])
    • New wiki page with short-term guidance for shifters [2]
  2. Issues:
    • BCAL noise at 10 o'clock
    • Bleedthrough
  3. Plan:
    • Continue production at 200nA with the solenoid on.
    • Since Hall A cannot run at present, we are the priority hall.
    • Maintenance day planned for Wed 11/03
    • Beam energy change planned for 11/05-11/07; decision pending due to availability of Hall A
