8:30 Ryan completes harp scans
9:20 Complete checkout for current scan
9:25  Ran spot ++
9:25  Ask beam off and put in single foil carbon target
9:29  Carbon target in
9:30  MCC called to say they need to reboot raster IOC
10:05 MCC restores 5 micro amp beam
10:10 quick recheck with spot++
10:30 Decided to move to detector alignment before doing current calibration
10:35 Helium target in place
10:40 Bob begins detector alignment with spectrometer DAQ
10:45 0.5 microamps on He target
10:50 Start with Det1:1850V, Det3: 1700V for kHz rates
11:16 Change Det1: 1900V, Det 3: 1800V for 30 kHz rate
11:45 Complete change of momentum from 2.7076 to 2.6530 in both arms
13:00 Start phase II high current commissioning of helium target w/o sweeper
13:15 Start run number 3656 for current calibration
13:35  Ramp up to 10 microamps
13:45  Ramp up to 20 microamps
13:50  Ramp up to 25 microamps
14:10 End run 3656
14:12  Ask for 2 microamps
14:20  37A on sweeper
14:23  74A on sweeper
14:28  111A on sweeper
14:30   10 microamps, 111A on sweeper
14:36   25 microamps, 111A on sweeper
14:50   35 microamps, 111A on sweeper
15:15   Still waiting for 35 microamps to stabilize. Talked to Eric Abkamaier 
and he agreed to set the trip level at 70 microamps at this raster (using a 
linear extrapolation). This should be sufficient for us. However, if we need to 
change the set points again, he is willing to authorize this remotely after 
talking to MCC.
