Events:
00:00 - Shift starts with trying to center the target
00:18 - Call from Karl, plan for tonight if we get to production is
to take 269M events at 0.8703 GeV
01:05 - Beam centering on hole target complete halog
01:50 - Checked beam position and slow raster on C12, the offset is
slightly different halog
02:20 - Checked beam position on NH3 bottom, offset of 12000 looks
good, start trying to do packing fraction run
03:08 - Still trying to complete packing fraction run, only a few
minutes of beam available the last hour
03:30 - Finished packing fraction run for bottom cup (only took 40
minutes...)
03:58 - Start dilution runs (LHRS 1.1511, RHRS 0.8703), not sure we
need this, but run plan isn't completely clear
04:45 - Done with dilution, but only have LHRS at 1.1511 (RHRS had
prescale problem, and we didn't go back and repeat them at this time).
04:58 - LHRS ramped to 0.8703, top cup is polarized, starting production
05:10 - Beam will be down for a while, cryo needs to come in to fix
trip problem with 2L09 liquid level Ops elog
06:03 - Beam back
08:00 - Shift ends taking production at 0.8703 GeV
Runs Taken:
Numerous runs for beam centering/spot checks
5133/41773 - Packing fraction bottom cup (LHRS elastic)
5134/41774 - Packing fraction for top cup (LHRS elastic)
5135/23971/41775 - Dilution Empty Target (LHRS 1.1511,
RHRS 0.8703) (right junk -> clock prescale was on)
5136/23972 - Dilution Carbon Target (LHRS 1.1511, RHRS
0.8703) (right junk -> clock prescale was on)
5137 - Dilution Dummy Target (LHRS 1.1511)
