Revision as of 09:19, 9 December 2021

Wednesday November 9

Last 24h:
- Start counter dark rate test, Run 90454 [1] (Beni)
- 1 FCAL base changed [2] (Mark)
- FADC replaced in the tagger crate[3] (Sasha)
- PWO modules and lead scint glass installed in the PS setup [4] (Sasha)
Issues
- Hall D beam stopper cause almost four hours of down time [5] We recovered the beam at 15:20 pm. The biggest suspect is an air pressure issue that caused a "beam stopper stuck" fault within PLC. The cause needs further investigation.
- Solenoid dumb due to a lost communication with both VCL flows for over 1 minute [6][7] (Tim & Nick)
- Solenoid ramping up, from 19:50 pm (Dec 8) to 4:30 am (Dec 9) up to 1360 A (Tim & Beni). Waited for 15 minutes and ramp down to 1350 A (Phoebe, Jackson & Nathaly) [8][9]
- Current major event, Separators tripped [10]
Plans
- Continue running with C
- AMO run
- Raw mode run
- Beam Studies next Tuesday (accelerator), Dec 14
