Summary from Saturday-Day (10/1/2022) to Sunday-Owl (10/2/2022)

General Summary
- The beam was back by the end of the Day shift. We got ABU for 34 minutes (Day shift), 247 minutes (Swing shift), and 341 minutes (Owl shift)
- We accumulated 395 Million events of CH2 with HWP IN configuration

Accumulated events (counted from the started time):
Saturday Day: 100.4 M (3.5 hours)
Saturday Swing: 116.2 M (4.25 hours)
Sunday Owl: 179 M (6.25 hours)

Total: 395.6 M events from 14 hours of running time
List of good run: 17118, 17119, 17122, 17123, 17125, 17129

Some Issues:
-  Tagger Magnet: During the day shift Tagger showed "temperature vault" and the read back is frozen. Called engineer on call and the problem fixed in about 1 hour
-  RICH & DAQ: During the swing shift, 2 tiles of RICH was inactive but showed 138 connected fiber (complete). RICH recovery fixed the problem. Then DAQ failed to start. roc reboot fixed the issue. During the owl shift, there was zero live time DAQ alarm where rich4 seems quiet. Fixed by RICH recovery.

Other issues:
- clas12mon: See some peak at "0" on the occupancy plot. Fixed by quit/close mon12 and open it again (https://logbooks.jlab.org/entry/4049622)
- LCW: Minor alarm on LCW return pressure. Fixed by changing the alarm limit
- Slow control: Alarm on Torus and Solenoid. Nathan is investigating.
- FTOF & PCAL: HV Sector 2 off. Fixed by turned ON HV
- BMT HV: HV trip on Sec3 L4 and Sec1 L4, fixed by power cycle

Plan: Continue data taking on CH2 until Monday morning where we swap the target material or further notification.
