Chao Gu(SL), Yuncheng Han(TO), Herun Yang(3rd)
16:00 Shift starts. We just start to take production data at 1.414GeV.
16:15 Hall C flipped IHWP to OUT.
17:15 Start to cycle Q2,Q3 on LHRS and set it to 2.2279GeV.
17:45 Start to drain LHe form the target nose to prepare for anneal.
Meanwhile Pengjia is taking a tungsten calorimeter calibration.
18:10 Hall is in controlled access. Dustin start target anneal. Alex
and Jack also goes down to the Hall to do some work.
20:15 Hall C flipped IHWP to IN.
20:30 Start to polarize the TOP cell.
21:05 Target is polarized. We called for beam and then took a packing
fraction run on TOP cell. We also start to production at 1.414GeV with RHRS.
21:15 Move LHRS back to 1.414GeV to continue production.
24:00 Shift ends. We are still taking production data at 1.414GeV.
