Summary of Sep. 5th

Owl shift

1. Shift summary by the shift expert: https://logbooks.jlab.org/entry/3841355
2. Issues: 0 beam. First recovering from a cold box crash, then recovering the RF.
3. Recorded data: 0

Day shift

1. Shift summary by the shift expert: https://logbooks.jlab.org/entry/3841463
2. Issues: Beam finally back and deemed acceptable (harp scans) at 10:20. However, it's quite ratty and trips a lot. On the plus side, the Halo Counters and the vacuum excursions seem to have calmed down a bit.Even the BOM and CTOF are a bit lower.
3. Recorded data: 18 M events on D2. Not exactly impressive.

Swing shift

1. Shift summary by the shift expert: https://logbooks.jlab.org/entry/3841736
2. Issues: Beam o.k. until 6, then off until 10. During that break, switched from D2 to H2
3. Recorded data: 12 M events on D2, 2.3 M events on H2

Whole day summary

1. Total recorded data today: 32.5 M events
2. Part-II total accumulated data on D2: 1.57 B events
3. Concerns: Beam continues to be iffy, with many major breakdowns taking it off for hours

Tomorrow daily RC meeting will be at usual time 12:00 PM using the link https://bluejeans.com/7576835804/
