16:00 Made access to move 3/4" carbon doors out, also
Mark Stevens reversing polarity of left arm magnets
and setting momentum to 496.1 MeV/c
17:00 SO in and turning fpp high voltages on
17:23 Left arm at 103.4 degrees
17:34 Back in beam permit, asked for 20uA, raster on
17:55 Moved to 15cm LD2 target
18:03 BPM jumping around, asked MCC to turn fast feedback on
18:27 Moved to 15cm LH2 target
18:45 Adjusted left arm D1 field reading to give proper momentum
(496.1 MeV/c), re-doing rate check runs with new momentum
19:18 Moved to 15cm LD2 target
19:25 MCC reports our fast feedback is tripping their DAQ, shut off for
now
19:34 Starting with Gamma D production data: LD2, 5% radiator in
21:06 MCC called to say they were taking beam away for 10-15 minutes
for PZT tests
21:21 MCC called: tests done & beam back
22:25 Right arm coda died
23:30 Right arm rebooted (finally)
23:45 Right arm coda freezing again
