08:00 Shift starts with production at 1.082GeV momentum setting.
08:50 3rd arm saw a >10k rate. We did a 10 min quick study on beam
position and slow raster size. Change back to what we used on Saturday
(0.62VX0.80V). New beam position is BPMA(1.2,-5.0) BPMB(0.3,-4.0)
09:00 Hall C is down for 15 min. Our beam energy changed during this
time. Talk with MCC, they suggests us to wait Hall C back. Beam energy is
recovered at 9:15
10:50 Finished production on 1.082GeV, moved HRS momentum to 1.0063GeV
11:00 Start production at 1.0063GeV
12:35 Bleed through test, the result is 0.33%
14:00 Moved to Top cell, polarized it to 45% and continue with production
16:00 Shift ends. We were still taking 1.0063GeV momentum production data.
