08:00 Shift starts with no beam (since about 02:00) due to one of the arc magnets' power supply problem.
08:40 Got call from MCC saying that we may get beam. Moving the target ot BeO to start the long beam recovery procedure since the beam has been down since 2:35 AM.
08:48 got beam for the spot check.
09:11 Target moving to 3He - 20 cm.
09:17 Asked for 1 uA beam for the beam recovery procedure.
09:21 Asked for 120 uA for production data.
15:08 Hall C is asking for changing the half wave plate IN->OUT.
16:00 Beam of the shift, shown in Figure 1, has been very trippy. The blue trace is hall A beam (default value 120 uA) and the gray trace is hall C beam (default value: 165 uA).
Production run list on 3He 20 cm target at 120 uA:
4053 Half wave plate changed from IN->OUT by Hall C's request
Runs 4050-54 had very trippy beam
