Logentry Text:
Very efficient running since yesterday morning. We completed the Q2=5, SHMS center running around 1:15 pm. At that point we rotated SHMS to 8.17 deg remotely and we started data taking at Q=5, SHMS left at 1:31 pm. We have been running very smoothly with no downtime on the hall side and fairly minor beam interruptions in beam delivery from the accelerator.
Since yesterday's SHMS angle change we accumulated 33% of the goal statistics on cryo.

The pass change for Hall B will start between 10 and 10:30 am today and some interruption in beam delivery to the other halls is expected. 


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