Logentry Text:
Got beam set up to the Hall towards the end of swing shift. Trippy beam throughout owl. Better at start of day. 

We are currently on 3He production at 27uA. Target polarization around 44%. 

Planning for tomorrow's access:
-Radcon here at 8am to sweep the hall. 
-When beam is taken away and prior to sweep, we will rotate HMS from 20->29 deg for cerenkov work. 
-Target polarization change from 270->90 must begin ASAP when beam ends. 
-Around 4-5 hours of work in the Hall (cerenkov, HMS Q1 vacuum, and EPR photodiode swap??-TBD)
-Steve L will update HMS software during this time (remotely, no access). 

We will meet today at 4:15pm via Bluejeans 861439920: https://hallcweb.jlab.org/wiki/index.php/RC_Update_and_Run_Plan_for_Aug_10,_2020
