Owl Shift Summary:
0021: MCC trying to locate and reboot ioc for Hall A BPM's (iocha10)
0055: BPM readouts back, asked MCC for a harp scan at 5uA (BeO)
0115: MCC needs to cycle a quad and rerun the harp scan
0130: Harp scan (190 um): Starting to work on raster and beam center.
0158: Raster established at 2.3mm x 2.3mm, working on beam spot
0204: Beam spot within spec, asked MCC to mask target motion.
Runs 3610-3613 (JUNK)
Runs 3614-3618 (Raster and spot calibration)
Run 3619 (JUNK)
Run 3620 (He3 production, raster at ~2mm x ~2mm)
0245: Requested raster increased by 15% (now 2.3mm x 2.3mm on spot++)
0247: Run 3621 (He3 production)
0317: End run 3621 on unstable beam. Request reduction to 90uA
Good stable beam over last three hours...
0605: Requested 95uA from MCC...to see if it will remain stable.
0615: It won't remain stable at 95uA...request return to 90uA
0642: MCC called, going to try for 105uA
0700: Running at 105uA...reasonably stable
0745: Good stability at 105uA
3620 (2x2mm raster, 105uA, 366k)
3621 (2.3x2.3mm raster, 105uA, 0.98M, ended on unstable beam)
3622-3625 (1.25M events, 90uA)
3626-3627 (1.25M events, 105uA)
0801: Run 3628 in progress at end of shift.
