- Notes from the previous 48 hours:
- CEBAF:
- More PSS drops over the weekend. General rhythm: Day shift fixes it by swing. Swing tries to establish beam to halld. Machine has issues over night, which are fixed during day shift
- Issues with extracting beams to halls A/B/C meant it was all halld Sunday
- Sunday evening saw more CW beam but issues with positioning. Ultimately tagger magnet was increased by 1A and finished fixing the position issues.
- Overnight saw some straight track running with Hovanes doing the flux optimization today.
- SL access today, providing time to attempt repairs to the solenoid (may be a comm issue)
- Action Items:
- Issues: Solenoid PS
- Reports:
- Run Plan: Hovanes flux optimization/AC calibration. Sergey DAQ work. CDC HV scan? Detector calibrations?
