continuing alignment (led by Seamus):
16:36 -- Carbon hole spot++ looks strange, moving to BeO viewer
16:38 -- 5uA on BeO viewer; hard to see anything
16:53 -- MCC is restarting fast feedback
17:11 -- moving to Pb/D #1
1567: 12x8 MCC (6x4mm) raster at (0,0) for both A and B, T4 trigger
1568; 16x16 MCC (~8x8mm) raster at (0,0), T4 trigger
1569: 16x16 MCC (~8x8mm) raster at (0,0), T1 trigger
no evidence that we're hitting the frame.
1570: 16x16 MCC, both BPMs (X=0, Y=-1), T1 trigger
17:39: MCC is going to start ion chamber calibration for Pb/C #1 up to 30uA, with raster 12x8 in MCC units, both BPMs at (0,0).
We'll use parasitically for temperature tests and detector checkout.
18:30: Target moved to empty & raster off (so MCC can check beam position on dump viewer, establish baseline for heating test)
18:39: Moving to Pb/C #1, re-establishing 12x8 MCC raster for permanent magnet heating test
18:47 ramping to 25 uA for magnet heating test
19:53 moving target to empty to test high-temperature beam spot
19:57 MCC confirms beam on dump viewer, with magnet temperature of 90 degrees. No observable motion. See MCC ELOG #1532384
20:15 Taking detector checkout runs at 0.5uA, using triggers T3,T4,T6
(first run: 1596)
20:24 MCC: Moller quads have been down since about 1pm, adverse effect on optics likely. They tried to cycle, but Moller quads did not come up.
20:25 Right-HRS Q1 is down, "main power off" error.
20:46 Requested 0.5uA on Pb/C #1, for L-HRS checkout run.
20:54 Requesting escorted access so Alex can try to reset right-HRS Q1 power supply.
21:30 Q1 fault was cleared.
21:36 Request 0.5uA on Pb/C #1 for R/L-HRS checkout run.
21:41 Moller quads are back up; checking spot++ with tune beam
21:51 Checkout run (1600) with T3 on,
21:54 Spot++ run (1601) on T1.
21:56 Request controlled access to work on detectors
