Logentry Text:
Another 24 hours of really good running. No downtimes on the hall side and minimal interruptions in beam delivery from accelerator. This morning at 9 am we completed the cryo running at Q=5, low epsilon, SHMS center. We are currently taking data on the dummy target and we should be done with that around 1 pm, if there are no significant downs. We will then rotate SHMS out from 6.17 deg to 8.17 deg (Steve Lassiter will watch remotely). We will then resume data taking on LH2 at Q=5, low epsilon, SHMS left.

A pass change is schedule for Hall B starting with 10 am on Monday. Starting with 7:45 am on Tuesday Ops will take beam away for 3-4 shifts for the 2L18 cryo bump exercise. The expectation is that beam delivery to the halls will resume sometime during the day shift on Wednesday. I will put the SLs for Tuesday day, swing and Wednesday owl on standby. The TOs must arrive for their shifts as usual.
We will be in controlled access on Tuesday during day for maintenance work.

We will have a RC meeting today at 10 am: https://jlab-org.zoomgov.com/j/1607100885?pwd=ZFBsRTFsYm5Zb0laZ0tyZXNjcEE0QT09
