00:00 Shift start. We are now taking P0 = 0.968GeV production data.
00:10 Suddenly find that beam current is 60nA start from previous shift.
So we asked MCC to move the beam current back to 50 nA
01:45 Set the HRS P0 to 0.900GeV. Start production with this momentum setting
03:50 We find that the raw data file of run 3886 overwrites the data file
of run 3885, we lost one run
04:10 Finished 0.900GeV setting, start to take dilution runs
04:40 Set the HRS P0 to 0.837GeV. Start production with this momentum setting
07:10 Finished 0.837GeV setting, start to take dilution at this momentum
07:50 Set the HRS P0 to 0.778GeV, Start production with this momentum
08:00 Shift ends, right arm momentum is still moving, so we start to take
data with left arm
