owl shift summary
beam was really good. beam position was really stable. there is some issue with the left arm spec + carbon target. in addition, the coil currents in both pairs of helmoltz coils were drifting all night. this may have caused our EPR attempt to fail.
0000:0052 kin 10.11, Pol 3He, 270 deg, BHWP = IN
0052:0056 BHWP = OUT
0056:0242 kin 10.11, Pol 3He, 270 deg, BHWP = OUT, bleedthrough = 2,09%
0242:0323 changing to kin 10.12, rotate 270 -> 0, move to ref cell, NMR = 38.5%, EPR failed
0323:0333 MCC called: no beam
0333:0343 kin 10.12, ref cell=empty, BHWP = OUT
0343:0349 filling w/ 140 psig N2, bleedthrough = 1.03%
0349:0355 kin 10.12, ref cell=N2, BHWP = OUT
0355:0406 moving to Pol 3He, increased BCM from 5 to 7 microA
0406:0528 kin 10.12, Pol 3He, 0 deg, BHWP = OUT
0528:0531 BHWP = IN, bleedthrough = 0.72%
0531:0646 kin 10.12, Pol 3He, 0 deg, BHWP = IN
0646:0705 rotating to 270 deg
0705:0729 MCC: no beam, reboot IOC
0729:0800 MCC: no beam, mo money, mo' problems
