[Clas12_first_exp] RC Update and Cancelled Meeting

[William Phelps]

Hello Everyone,

Yesterday we had no beam in the hall from 9am until 2:35pm due to a master oscillator issue and some RF issues in the north linac. After MCC returned 5 nA beam to the hall we were seeing high counts on the upstream and midstream counters. We investigated the source of the high count rate and determined it was our beam. After several hours MCC was able to restore physics quality beam to our hall at around 7:15pm last night after some adjustment to the beam steering/path near the seperator. Since then we have had stable beam with some hours having 57 minutes of ABU!

Unless anyone has anything they would like to discuss then I will cancel the meeting. The run plan is to continue taking production data at 50 nA until beam studies on Monday.

Thanks,
-Will
