00:00 Shift starts. We are taking production data on LHRS at 1.8857GeV,
RHRS at 1.3509GeV
01:20 Finished production on both arms. Start to take dilution data.
01:40 Dilution finished. Pengjia took 10 min to check BPM resolution
when we are ramping right arm.
02:00 Start to polarize the top cell.
02:45 Polarizing the target took about 40 minutes. Start to take 2
production run with left arm at 1.7348GeV. We also start to take
production data on right arm at 1.2698GeV
03:10 IHWP is flipped to IN by Hall C.
03:35 Move LHRS to 1.5961GeV and take 2 production run with this setting.
04:35 Start to take dilution runs at 1.5961GeV on LHRS.
05:05 Move LHRS to 1.4684GeV and start to take dilution data.
05:25 Start to polarize the TOP cell.
05:50 It took 25 minutes to polarize the target. We start to take
production data on LHRS at 1.4684GeV and continue the 1.2698GeV data
taking on RHRS.
07:10 IHWP is flipped to OUT by Hall C.
07:40 Start to set RHRS to 2.2279GeV to prepare for optics. Meanwhile
we will keep taking production data with LHRS at 1.4684GeV.
08:00 Shift ends. We have got 25M with LHRS at 1.4684GeV. We need to
take 26M at 1.3509GeV and 29M at 1.2698GeV with LHRS to finish these 2
momentum settings.
