Summary of Sep. 6th
Owl shift
- Shift summary by the shift expert: https://logbooks.jlab.org/entry/3841968
- Issues: Ratty beam, DAQ issues.
- Recorded data: 13.3 M events on H2
Day shift
- Shift summary by the shift expert: https://logbooks.jlab.org/entry/3842229
- Issues: Still ratty beam.
- Recorded data: 26.7 M events on H2
Swing shift
- Shift summary by the shift expert: https://logbooks.jlab.org/entry/3842510
- Issues: Switched to empty (1-3 psig H2) target and increased beam current to 300 nA. Maybe a mistake - the 2H01 vacuum problem came roaring back with a vengeance. Stopped beam and explored in the Hall. "Fixed itself" for now - continue with 4He. Followed by Moller measurement (80.6%) and back to D2.
- Recorded data: 5.4 M events on MT.
Whole day summary
- Total recorded data today: 63 M events (H2/MT/He/D2)
- Part-II total accumulated data on D2: 1.57 B events
- Concerns: Continued beam troubles and equipment failures in accelerator; 2H01 vacuum issue (may have to fix beam exit window).
Tomorrow daily RC meeting will be at usual time 12:00 PM using the link https://bluejeans.com/7576835804/
