Shift starting with efficiency run 9306

12:23 - Moved to optics target for 30 minute optics run (run 9307).

12:35 - Noticed fast feedback was turned off. Called MCC and had them turn it back on.

01:00 - Done with optics run. Back to 15cm LD2 target and production running.

01:50 - Bob called to say that the disk had become full (and, subsequently, the coda run crashed). Changed pingpong script to USEADAQL1=1. Restarted coda.

05:55 - DVCS ioc crashed. Rebooted. Although the calorimeter PMT currents are now responding, the rates are still all zero, so rebooted a second time... Turns out the correct tab to look at on the scaler data GUI is the 4th one... the rates are fine there.

06:56 - RF separator trip. Since there was a scheduled beam studies at 07:00 anyway, MCC will not bring the beam back up. Requested controlled access.

07:55 - Hall in controlled access and ARM is starting the survey.
