Continue production running at 200nA with a empty target until further notice, most probably on Wednesday. 1.2B triggers as of Tues 7:30am
HA down until estimated 9pm, HB down, HC reconfiguring until tomorrow swing

Emptied the target on Monday morning.
6am this morning BCAL fadc problems, excluded from daq will be replaced later, along with FDC fadc

Continue production running at 200nA with a full target until Monday daytime
Plans from MCC: A off for 24h, B down, C doing target change until Wed swing probably
Note that MCC will be doing operator training during owl shifts until Dec 2

Production running with full target, 15B triggers this cycle (Monday 8am)
Filled the target on Wednesday morning after approximately 2B triggers with empty target.
Raw mode cosmics run 111571 (Beni)
FCAL base changed (Malte)
Several locked up FCAL bases reset Wed early riser Wed day Fri early riser
The top alcohol bubbler has been filled.
The empty Ar cylinder has been swapped out.

CCAL alpha trigger missing since 111646 from HistMacro_Trigger_PrimEx
Reconstructed Beam Energy monitoring plot discrepancy in recent runs (Drew)
No beam for ~2h Saturday with vacuum issue, ~1h with trips in swing shift. Also see the drama section.
The CH kitchen light switches off automatically but does not switch on automatically, is it supposed to? Better to switch it off on exit. Aha, the sensor is in the entrance foyer between the 2 sets of doors.

Wednesday pm - cooling water outage summary and more stripcharts. We lost about 2h beam-time time fixing problems and waiting for the target to refill; it was another 2h before the BCAL chiller temps returned to normal.
Monday 1am - NFS disk errors caused multiple DAQ problems. Sergey was called in.
Monday 2:30am CCAL HV unit D2-8_MID lost communication, reported 0 V restored after access to reboot
