The beam are good and stable over the weekend. We complete one production cycle for KinC_x36_2' and KinC_x36_2, and 80% of runs for KinC_x36_2''. None of those angles needs NPS sweeper magnet's corrector on. 

https://logbooks.jlab.org/entry/4222968 (NPS 16.6 deg)
https://logbooks.jlab.org/entry/4222505 (NPS 14.36 deg)
https://logbooks.jlab.org/entry/4221863 (NPS 28.76)

Here are the Coulombs collected for each kinematics calculated by Josh:
    KinC_x36_2':  320 mC on LH2, 250 mC on LD2
    KinC_x36_2 :  320 mC on LH2, 176 mC on LD2
    KinC_x36_2'':  382 mC on LH2, 159 mC on LD2
which is about 30% of the goal (1.1C)

Hall C will be in controlled access around 9:30 am. NPS team will swap 10 PMT bases. Then we will come back to KinC_x36_2''. The beam study on Tuesday is cancelled.

Notables things happened in the past two days:

Moller measurement on Saturday shows 68.2% of polarization: https://logbooks.jlab.org/entry/4222344

HMS ADC values missing and NPS pulse time shift happened around 11:30 am on Sunday due to a presale GUI issue. Bob and Chandan saved the day: https://logbooks.jlab.org/entry/4222917

Paul King noticed that a large charge asymmetry was developed over Saturday night: https://logbooks.jlab.org/entry/4222809

There will be a RC meeting at 11 am: https://jlab-org.zoomgov.com/j/1617015555?pwd=L09IQ216dml6ZmM5ODExVjFsMX...
