- Accelerator Status over the last 24 hrs
- Beam was mostly
- Stable until midnight
- Harp scans:
- Beam was re-focused around noon ELOG
- final MCC scans : IHA5C11, IHA5C11B
- Radiator HARP scans: Radiator Harp
- (Sigma_X, Sigma_Y) is (0.85,0.55), (0.65, 0.49), and (0.73, 0.43).
- new Harp scans as part of beam steering problem: MCC, Radiator Harp
- Beam was mostly
- Hall-D/GlueX items
- Downtime incidents of more than 30 minutes:
- DAQ 10:45 for about 40 min. , Sergey helped
- Beam position lock on active collimator steered the beam away: 00:15
- Traced problem to pre-amp problem in inner AC (dead or needs to be reset, power cycled ?)
- Total triggers collected: 1400 M
- Downtime incidents of more than 30 minutes:
- Issues
- Active collimator
- DAQ issues:
- difficult restart at 10:45pm
- Monitoring
- Run Plan
- Repair active collimator.
- HIgh luminosity ?
- Offline Analysis?
- Any Other Business?
Friday, February 24
- Accelerator Status over the last 24 hrs
- Beam was mostly:
- Stable : Beam current and positions
- Harp scans:
- Beam line, Radiator Harp, before AC repair
- (Sigma_X, Sigma_Y) is (0.85,0.55), (0.93, 0.55), and (0.64, 0.46).
- After AC repair: Radiator Harp
- Beam was mostly:
- Hall-D/GlueX items
- In the last 24 hours:
- Feb 23: Total triggers collected: M
- Trigger studies (Sasha)
- TRD test (Lubomir)
- Tested new tagger microscope settings for high luminosity (Alex)
- In the last 24 hours:
- Issues
- Active Collimator repair
- Rebooting IOC did not help
- Alex Barnes and Trent Allison found problem to be low voltage power supply, repair completed 11:55am ELOG.
- DAQ issues:
- Crash, Sergey helped recovering (approx. 45 min)
- Active Collimator repair
- Monitoring
- Low-level monitoring report
- Increase of FCAL channels with high rates:30770, 30778,30780, 30783
- Run Plan
- Current Plan
- Empty target run ?
- TAC run ?
- High luminosity ?
- Offline Analysis
- Any Other Business
