- 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.
