MCC whiteboard Meeting Bluejeans 660743227

Monday 01 November

  1. Over the weekend:
  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 on Wed 11/03 beam will be shut off at ~6am
      • Hall D will go into controlled access for maintenance work (FCAL, ...?)
    • Beam energy change planned for 11/05-11/07
    • Hall A scheduled to come back online on Monday, 11/08

Friday 29 October

  1. Last 24h:
    • Recorded 1090M+ events
    • Change out of C02
    • RadCon replaced light bulb (was 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 [6])
    • New wiki page with short-term guidance for shifters [7]
    • Beam - RF Timing differences with different trigger types
    • RAID beeping in DAQ room
  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 shifted to Wed 11/03
    • Beam energy change planned for 11/05-11/07; decision pending due to availability of Hall A

Thursday 28 October

  3. Plan:
    • Continue production at 200nA with the solenoid on.
    • Since Hall A cannot run at present, we are the priority hall.
