Logentry Text:
8/20 (Sat) 5-Pass Beam on NH3 Target (~50% polarization?)
Had overall ABU 14.7h, BANU 5.9h Total number of events accumulated ~180M
Most BANU, during the day and swing shifts, from 2 controlled accesses as RICH caused problems, eventually fixed ( ~4h ) related DAQ problems,  and the target anneal( ~1h, https://logbooks.jlab.org/entry/4031840 ). 
More details on RICH recovery available from Valeri (https://logbooks.jlab.org/entry/4031775, https://logbooks.jlab.org/entry/4031841) 

8/21 Day shift: Continue with 4nA on NH3 (HWP out since Run 16738) and negative target polarization. We plan to use PROD66_PIN for every next run, until next annealing.

No RC meeting today.
