Shift Workers:
Chao Gu(SL), Pengjia Zhu(TO), Min Huang(3rd)
08:00 Shift starts. We start to take production data at 1.2494GeV
08:25 IHWP to OUT by hall C.
08:40 BCM readout does not make sense. After check, we found that
downstream BCM is broken. Since we still have upstream BCM, we continue
to take data.
10:30 BOTTOM cell dropped to 60.5%, switch to TOP cell.
11:35 Start dilution runs at 1.2494GeV. Meanwhile we are moving RHRS
to 1.1745GeV.
12:00 Finished 1.2494GeV setting. Start polarize TOP cell and move
LHRS to 1.1745GeV.
12:10 Left septa tripped. We asked escorted access. Alex went down to
the hall to reset it.
13:00 Septa is back. We go back to production at 1.1745GeV.
14:45 Noticed we do not have packing fraction run on BOTTOM cell. So
I start to cycle LHRS to 2.2279GeV to take packing fraction run before
anneal.
15:00 Start target anneal. James is working on this.
16:00 Shift ends. Target anneal is still on going.
