Accelerator Status

Beam was off 09:45-13:30 on Sunday for a magnet issue that only impacted Hall C. Otherwise, steady production on day/swing/owl.
Pass change for Hall A is definitely Monday.
Regarding the Secretary of Energy tour, VIP schedules can change unexpectedly, but the last info we were given was that the accelerator will be off 09:30 Monday morning. Tours wrap up at 13:30.

We had good production at ~42muA starting 18:15 on Saturday, and continuing into Sunday day shift.
Immediately before that, there was no beam delivery to Hall C during 16:30-18:15. And most of Saturday day shift I would call QBU (questionable beam in use during 09:00-16:30) since our beam current varied from 6-40 muA while MCC was working the issue of BLM trips when trying to deliver requested currents to both Halls A and C.
Number of good pions was 4629 as of 08:00 Sunday. See Ali's hclog https://logbooks.jlab.org/entry/3931371
