MCC whiteboard Meeting Bluejeans 660743227
Friday 29 October
- 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]
- Issues:
- BCAL noise at 10 o'clock
- Bleedthrough
- 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
Thursday 28 October
- Last 24h:
- Recorded 949M+ events
- Emergency Control box intermittent alarms
- TAGH scalers froze (roctagh2); TAGH1 and TAGH2 crates power cycled
- Some issues with starting root spy (see day shift summary)
- 2.5hrs downtime due to issue with magnet shunt module (has been replaced)
- Chris C (target) requested access to check heater power supply of the condenser [3].
- Our rapid access beacon is not working again (turning, but no light!)
- RadCon escorted Chris in and out of the hall.
- Rebinning issue in compton monitoring macro
- Issues:
- Rapid access beacon gives no light. The same failure happened 2 weeks ago, light bulb was replaced [4]
- Low energy tagger counters?
- BCAL noise at 10 o'clock
- Bleedthrough
- Plan:
- Continue production at 200nA with the solenoid on.
- Since Hall A cannot run at present, we are the priority hall.
- Hall C BCM calibration moved to today (Thursday) 2:30pm.
- Maintenance day shifted to Tue 11/02
- Beam energy change planned for 11/05-11/07; decision pending due to availability of Hall A
