00:00 Shift starts. We are still waiting for MCC to bring beam back.
Meanwhile we start to ramp up the HRS and target magnets.
01:15 MCC call us to say they are ready to send us beam. We are
waiting for our target to be polarized.
01:45 Target is ready. We call MCC to send tune beam.
02:20 We ask MCC to move the beam position back to 1H01(-0.1,0.5) and
1H05A(1.3,-3.2). Took several spot++ runs, and the final plots looks
clean. So we go back to production.
03:20 C100 cavity 2L25 tripped. We do not have beam.
03:40 Beam is back.
03:55 RHRS finally settled at 2.2017GeV. Start production immediately
on RHRS.
05:10 IHWP to IN by us.
07:10 Start to move RHRS to 2.0696GeV.
08:00 Shift ends. RHRS is still moving to 2.0696GeV. LHRS is still
taking production data for 2.3422GeV. We finished 2.2017GeV during the
shift and collect 45.7M events with LHRS at 2.3422GeV.
