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.

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.
