- Accelerator Status over the last 24 hrs
- Accelerator busy with Hall C until 05:00
- Hall D first given beam at 05:20
- Data collection at 50nA started at 08:00
- Hall-D/GlueX items
- In the last 24 hours:
- Low-intensity production started at 08:00
- Long mode run (10 minutes) done at
- Current Total: 40.05B
- In the last 24 hours:
- Issues
- DAQ issues:
- 5:42 - The DAQ keeps giving us "SEBO: Client has not reported for xx sec." errors, but then recovers after a minute. This happens every ~20mins or so. We will restart the DAQ again after the current run finishes.
- ~22:00 - Monitoring stops working, have to start/stop runs several times to get events flowing through secondary ET
- DAQ issues:
- Monitoring
- low-level report
- Run Plan
- Production
- Triggers: In-time random? Min-bias? FCAL+BCAL+ST?
- Offline Analysis
- TAC runs?
- AOB
