1:00 Started taking data
1:50 Break for 1hour to fix hall B beamline.
6:10 Called tech on call to move spectrometer to the next setting (took appr. 18,000
elastic events for Q2=19.37)
7:35 Finished changing to kin. #16
7:53 Started kin#16
He3 (e,e) at Q2=19.37 runs:
1524 Good short run, 0.3M at 5.3uA ps1=2
1525 Good run, 0.5M at 7uA ps1 =2
1526 Good run, 1.5M at 5.3uA ps1=1
1527 Good run, 0.7M at 5.3uA ps1=1

1533 Good run, 1.4M, high deatime in the very end due to copying to MSS
1534 Good run, 0.04M (test prescale (ps1=2)
1535 Good run, 0.1M (ps1=2)
1536 Good run, 1.5M, ps=1, deadtime around 35% due to copying to MSS (ps1 is back to 1)
1537 Good run 0.3M, deadtime jumps to 70%
1538 Good run, 1.5M, ps1=1, 5.3uA, deadtime ~23%
