Shift workers:
Chao Gu(SL), Kiadtisak Saenboonruang(TO), Vina Punjabi(3rd)

16:00 Shift starts. We are taking production data for 0.8094GeV setting
with LHRS. RHRS is still moving.
16:20 RHRS settled. We start to take data on both arms.
17:30 Beam energy dropped by 0.2MeV. Ask MCC to check, and they moved it
back.
19:30 IHWP changed to IN by Hall C, we have 115M events at this momentum
taken with IHWP OUT
20:40 We found that the previous shift crew forgot to turn on the Q1
regulation when they are moving the LHRS momentum setting. We are using
wrong Q1 current start from 15:20 (5160-5175). I moved it back.
24:00 Smoothly take production data until midnight. Shift ends.
