Day shift summary:
8:00 shift started with no beam. Accelerator recovering from a main power breaker failure.
9:00 oppotunistic controlled access for detector, target and spectrometer work.
10:50 MCC caled, they are ready to send tuning beam.
11:07 -Run Coordinator recommandations:
when beam comes back one should ask that MCC saves the beamline and loads the new file that J. Benesh has produced (elog - entry 1218415) and run spot++ to check that the raster is effectively 4*4
11:10: Left Q1 tripped and reset.
11:20 Back to beam permit. Moved target to BeO for beam tuning.
-12:25 MCC tuned beam with old optics and saved. Then loaded new optics, Tuned beam. We did raster check.
12:30 Moved to 4He target, started target tests.
1x1 mm raster, 28 uA.
Fan speed 24 Hz., 40, 50, 60 and 70 Hz.
Then repeat with raster=3.5x3.6mm (max).
13:40-14:20 test with target operating temperature vs cooling power.
6.6K to 7.6K give extra 115W HP heater.
14:35-14:51 dithering run 2125
Get back to production run
15:00 run 2126, Compton is tuning while the run is going on. position
