keyword=Swing shift summary
No beam at start of shift, due to G0 beam work. Don't know exactly what work is being done, but since the beam switchyard is in controlled access, we're not too optimistic.
18:55 MCC delivers beam - 100 microAmps - start run #2763 (scintillator efficiency run).
19:15 Due to frequent trips, MCC wants to play with current/FFB/position to try and cut down on the losses. We end run 2764 while they are playing with the beam.
19:30 Beam back at 100 uA - start 2765. MCC tried 110 uA briefly, but it appeared that it might have made the trips worse so we went back 100 uA.
Around 19:45, the beam was relatively stable (not too many trips, but it is taking a couple minutes to recover from each trip.
2763 - Scin. efficiency run - 100 uA - 1M events.
2764 - Q3D_e40 - 100 uA - lots of trip during run - stop at 79k
2765 - Q3D_e40 - 100 uA - fairly stable beam - 1M events
2766 - Q3D_e40 - 100 uA - 1M events.
2767 - Q3D_e40 - 100 uA - 1M events.
2768 - Q3D_e40 - 100 uA - 1M events.
