Swing Shift Summary:
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Plan: SRC Production 755 MeV/c
Kinematic settings:

    energy = 4.452 GeV 
    left HRS P0 = 3.6014 GeV/c
    left HRS angle = 20.3 degs
    right HRS P0 = 1.19635 GeV/c
    right angle = -24.5 degs

16:00 Continue taking production data; Pmiss = 755 MeV/c
17:50 bbps1:2008 left-side HAND HV turned off.
17:55-18:01 N4 #7 left-side HV tripped off four times.
17:49 N5 #3 right-side PMT tripped off.
20:06 N5 #3 right-side PMT tripped off.
20:13 N5 #3 right-side PMT tripped off.
20:41 N5 #3 right-side PMT tripped off.
21:08 Beam HWP OUT from Hall C request during run 3365.
22:25 MCC called. They have multiple beam trips and will bypass two cavities. Expected time 5 minutes.
22:26 Ended run 3366 early.
22:36 MCC is ready to send beam.
23:18 N4 #7 left-side HV tripped off.
23:53 Run 3368 started.
