RC Report -- 01/28/23

Run update:
Very smooth running on polHe3 since beam was restored yesterday morning. We have accumulated over 2.5 C since then with only a few minor DAQ issues that were quickly resolved. Many thanks to the shift crews.

Issues:
Ops informed us that ODH OM01is reading a little low. Upon investigating, it seems it has been since some time on Tuesday. Other monitors in the hall are reading normal. SSG have been informed and no further action is needed at this time.

Run plan:
Production data-taking to continue until 4am Monday. Ops will then start tuning for our first Moller measurement, with the expectation that the Moller crew will start around 5am (Faraz checked things out yesterday). Beam will then be unavailable for ~4 hours for a Wien angle change. We will take another Moller measurements once beam is available before switching back to production. A maintenance day is scheduled for Wednesday.

Special requests:
In the event of an unplanned down period, Hall C have requested that we inform them so that they can do a BCM calibration up to 60 uA (for around 1 hour).

Meeting:
Probably no need for an RC meeting today. I am available on the RC phone (or email) if anyone has anything to discuss.
