- Accelerator Status over the last 24 hrs
- Beam was mostly
- 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
- 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
- Issues
- Active collimator
- DAQ issues:
- difficult restart at 10:45pm
- Monitoring
- Run Plan
- Repair active collimator.
- HIgh luminosity ?
- Offline Analysis?
- Any Other Business?

- Accelerator Status over the last 24 hrs
- Beam was mostly:
- Stable, beam off due to weather [DAY], [SWING]
- Down times
- Harp scans: None
- Hall-D/GlueX items
- some FCAL HV settings needed to be adjusted [[2]]
- In the last 24 hours:
- Total triggers collected during last period: 3,250 M
- Run Statistics Spread Sheet
- Current Total: 31.88 B
- Issues
- DAQ issues:
- repeated problems: live time issues, crashes [[3]] probably due to high rate
- rootspy occasionally hangs
- [[https://logbooks.jlab.org/entry/3462529 Disconnect message
- reduce current for AMO to 150nA due to reduced live time (70%)
- Monitoring
- Run Plan
- Take production data at 150nA
- perform Harp scans

- Accelerator Status over the last 24 hrs
- Hall-D/GlueX items
- In the last 24 hours:
- [Preparation for TAC run], time required for switching ~ 1 hour.
- TAC run with 1 mm insert collimator: 2 runs, 30852, 30853 combined total of 3.2 M events
