[Clas12_first_exp] No RC meeting today on Sat, March 31st

[kenjo at jlab.org]

Dear all,
MCC was trying to deliver high current (80uA) to Hall C for their boiling
studies yesterday. In order to achieve it they turned off Halls ABD. As
far as I know they didn't succeed, and reverted back to delivering beam to
Hall B at 19:15. Beam was unstable during the remainder of swing shift
with frequent trips. We resumed our production data taking at 50nA. Beam
became more stable at the end of swing shift and remained stable until 8am
when MCC had orbit instability issue:
https://cebaf.jlab.org/dtm/open-events?event_id=3503. Yuri used this time
to have rapid access to the Hall to check SVT cooling system. As soon as
beam is restored we are going to restore production data taking.
Please let me know if you want to show or discuss something wrt recent
data and/or plan for weekend. Otherwise RC meeting today is cancelled.
Best,
Andrey.
