After fixing the bigbite power supply yesterday https://logbooks.jlab.org/entry/4187236, bigbite didn't trip again during the swing and owl shift.

We went to beam permit just before RC meeting yesterday, and followed the beam recovery procedure. Shift leader has issue with DAQ while taking carbon hole run, and GEM expert helped to fix it remotely. Beam checkout is completed around 6pm and we started production run on polarized He3 @42.2% polarization. We continued production run until around 3:20 am. After that MCC stopped sending beam for BSY corrector testing, andLI NAC maintenance. MCC is planning to recover beam during the swing shift today.

accumulated corrected charge during during swing +owl shift = 0.399 C

RadCon started surveying the hall around 9 am this morning, and we are in controlled access now. Subsystem (detector) experts are accessing hall to fix the issues related with detectors [I expect to get updates from experts during the RC meeting]. Target group is scheduled to access the target enclosure for field measurement starting from 1:30 pm today (Radcon and hall techs are ready to support this).

There are still some open slots in the shift schedule, so please consider singing up for those shifts https://misportal.jlab.org/mis/physics/shiftSchedule/?experimentRunId=SBS-GEn-2022

We will discuss more during the RC meeting at 3:30 pm today at CH conference room. You could join remotely using the following info:

[Special Note: RadCon found that a rope was taken out from their cabinet and used for other purpose in the hall, and asked not to do it again. The color rope is only used by them to allocate the radioactive boundary]
