keyword=Swing shift summary
4:00 Shift started with the Hall in controlled access to fix the left HRS
4:00 Technician leaving the Hall (left dipole still down). We asked MCC for the
beam back. They said they are doing a quad scan so it will take about 30min
before they can put us back to beam permit.
4:25 Turned the VDC back on.
5:25 MCC called. They will establish the beam in the hall.
5:32 Beam is established. We move to C12 target. Request 20 uA.
17:42 we have 20 uA in the hall for detector and DAQ check. We start
non-production run #4892 (right arm).
17:48 Detectors & DAQ are fine. We stop the run, and called MCC to mask the
target in order to move to empty. Then Tehy will start Compton tune.
18:25 Jack came and cleared a fault for left arm Q1. We are ramping up Q1 (the
point is that we have symmetric fringe field for using the lumi)
18:28 Compton HV trip (followed by many others)
20:25. MCC called. Beam is tune on the target. They will send high current beam
now, straight (i.e not through the chicane).
20:35 MCC called and say they are happy with their tune. They are trying now
throught the chicane.
20:55 We called MCC for update. They have back out of the chicane and are
redoing the straight-trhough part.
21:53 MCC called. They are done with the straight tunning. Now they will try
through the chicane.
22:15 Compton tune is done. We move the target from empty to carbon. Starting
target edge scans.
23:55 Target study completed. Preparing for production. Ramping down the VDC HV.
00:00 requesting 100 uA.
