keyword=Shift summary0:00 CODA still flaky
2:20 MCC called they need to work on a power supply, if what they will
try does not work, they might need to call somebody else so no beam for some time.
03:30 Calorimeter LED run (new block positions). Run 2939.
03:45 Called MCC to get an estimate : 3hours...
04:33 Run cosmic (config not working)
04:52 Pedestal run (DVCS config with calorimeter threshold=5,5, no beam). Run 2946.
05:10 More detailed scan of calorimeter blocks 0,11,120 and 131 with LED (step size 1mm). Run 2947. Estimated time 95min.
05:15 MCC called : ready to send beam. Stopped LED run and taking 2.5uA.
05:25 Want to check beam. Called MCC to change the target to empty and do a harp scan.
06:03 The beam doesn't look good yet. Putting BeO target to have a look.
Looks ok.
06:16 Back to empty target and redo harp scan. After several iterations with MCC, beam is now within the specifications (06:29). We asked for tuning position at BPM4B-y to 1.4 (was 1.2).
06:35 Going back to 15cm-LH2 target.
06:39 Taking back 2.5uA.
06:43 Finally beam back. Returning to production runs.
