Shift crew ***Marat Rvachev, Xiaodong Jiang, Christophe Furget***
3:00 Got beam. MCC says the maximum current they can give is 60uA now, to
increase that they would need to call injector people and stop beam delivery for
~4-6 hours. Hall B has priority now and wants to run. Agreed that MCC will call
injector people first thing in the morning.
Started harp scans
2330 7 hour cosmic run, some pulsed beam in the end (empty target)
2331 Empty target, harp scan (run #554) with no raster
2332 He3 target, harp scan (run#555) with raster on(4*4 on spot++)
Checked beam position on BeO target. Beam hits the center of the target (see
halog entry).
4:10 Kin 13 runs He3 at 54uA:
run#....events.......time.....corr_time_sum
2333....1M............1h........
2334....1.6M.........1.5h.....
2335....1.2M.........1.1h........1.8h
2336 goes into next shift
corr_time_sum is time corrected for the fact that the current we were
running at is appr. twice lower than in runplan.
