Shift Crew: Vincent Sulkosky (SL), Byungwuek Lee (TO)
Major Events:
-------------------------------------------------------------------------------
16:00 Begin shift during energy change.
16:23 Move target to BeO in preparation for beam.
17:15 Moved Right spectrometer from 15.28 degs to 23.11 degs.
17:20 Ed Folts has moved the left spectrometer from 140 degs to 120.76 degs.
17:45 Nudged Right HRS angle to 23.122 degs.
18:17 MCC called to give an updated. The estimate for tune beam in Hall A
is 8:30 or 9 pm.
18:20 Change Right HRS momentum from 0.6840 GeV/c to 0.6503 GeV/c. Quads were not
cycled.
18:22 Cycle Left HRS Q2 and Q3 to 1600 A.
18:33 Change Left HRS momentum from 0.5753 GeV/c to 0.6101 GeV/c.
19:42 MCC called. The beam dispersion is bad. They need to retune the beam.
Probably another two hours are needed.
21:35 MCC called and they are ready to bring us to beam permit and send tuned beam into Hall A.
22:46 MCC called with an update. Finishing up the tune and RF separation.
22:59 MCC is ready to send tuned beam to Hall A.
