[Clas12_first_exp] RC summary and no meeting today

[mdefurne]

Dear all,

Yesterday was not a  very productive day. After the issue at the 
injector that limited our current at 16nA for part of the owl shift, HV 
on a cavity was lost around 11:40am (not the first time it happened). So 
MCC took some time to investigate the problem while fixing it. Beam was 
back in the Hall only at 8:55pm.
Then, at 9:00pm, we got DAQ issues and Sergey had to go in the Hall 
because he could not access remotely some machine: Apparently there is a 
bad network switch which needs to be replaced on Monday (bethsw10... I 
think it is also the one responsible of the communication loss with 
HVECAL2 last wednesday).

11:00pm, Beam is back and DAQ ready, so production is resumed. So far, 
things run quite smoothly.

Tomorrow, during the RF recovery, the Hall will be in controlled access 
starting at 8:00am: There will be work/studies on solenoid, the network 
switch replacement. Eugene will also do a walkthrough.

We should get the beam back early in the afternoon (1pm-2pm is fairly 
optimisitic).

Today there will be no meeting. Do not miss the run coordinator report 
at the Hall B meeting tomorrow,

Kind regards,

Maxime
