- Last 24h:
- Issues:
- Solenoid dump at 11:30 am
- Traced to defective Convectron panel meter [1]
- Started ramp back up at 14:33
- Solenoid dump at 11:30 am
- Plan:
- Continue production at 140 nA on diamond
- Analysis update
Monday, November 22
- Last 72h:
- Recorded ~2.5B triggers on LHe
- Took some data (~100M) with COMCAL inserted into the beam: Trigger/DAQ/Data rates
- Took ~39M (production) triggers on LHe at 50 nA: Trigger/DAQ/Data rates
- Took ~33M triggers on LHe empty target: Trigger/DAQ/Data rates
- Switched to Liquid deuterium during swing shift on Saturday: Target cooling
- Trigger/DAQ/Data rates at 140 nA: 68 kHz w/ 96% live time
- Took ~5B triggers (192M AMO): [2]
- Recorded ~2.5B triggers on LHe
- Issues:
- Plan:
- Continue production at 140 nA on diamond
- Analysis update
Friday, November 19
- Last 24h:
- Repair work for RF separator did not end up impacting taking beam -- yay!
- Added ~2B triggers: [3]
- Issues:
- A couple of minor issues:
- DAQ computer acting weird, but this did not impact actual data taking
- Alcohol bubbler too dark to see: [4]
- A couple of minor issues:
- Plan:
- Continue production at 150nA on diamond
- Saturday day: Low current + empty target?
- Saturday swing: switch to liquid deuterium
- Analysis update
Thursday November 18
- Last 24h:
- ~1.4 B triggers (250M AMO): [5]
- Down from ~8:45 am -> 9:30 pm due to 4th pass RF separator problem
- Repair plan: down at ~10 am for ~30 minutes, then acc will decide if full system needs to be down for repair for longer time
- Some discussion regarding using magnetic separation for 1 hall running if down more than 30 minutes
- Issues:
- writing on tape?
- High temperature of locked-up FCAL bases? [6]
- Shift crew will take over servicing FCAL base lock ups. wiki instructions
- Plan:
- Continue production at 150nA on diamond
