keyword=Swing shift summary
16:00 Start swing shift. Waiting for MCC to finish the energy change. Expect to
get beam back around 5:30pm.
Theta_L=12.5 P_L=3.9250Gev
Theta_R=47.491 P_R=1.4999Gev
18:51 MCC informed us there are ready to send some CW beam to Hall A.
Ask them to send 5uA with raster off to do the harp scan for beam check.
19:05 MCC is still working on the fast feedback.
19:54 Change the target to He4 while MCC is still working on the fast feedback
problem.
20:10 Beam back to Hall A. Start taking elastic data.
20:46 Stop run 1825 due to RF problem.
21:56 End run 1828.
Change L-Arm momentum to 3.093Gev. Change to He4 target.
22:09 Start run 1829, 5uA (Current scan)
22:30 Start to change L-Arm angle to 20.85. Having problem with the moving
of the L-Arm spectrometer. The bogies tripped frequently. Ed Folts is coming to
check the problem.
23:28 Finally finished the L-Arm angle change.
Ask MCC to send 70uA.
23:35 MCC informed us they need to take off the beam due to injector problem.
23:43 Beam back to Hall A, 70uA.
