Entry number 159738

keyword=Swing Shift Summary




16:00  Start shift with last run of IHWP=IN slug (run # 6328).

16:30  Approximately at this time, noticed white entries in Hall A

       Tools (Left arm magnets).  After rebooting iocha14 saw that

       Left arm magnets were down (Halog 159711).  

16:50  While bringing LEFT arm magnets up and cycling Q2/Q3:

       Ask MCC to cycle Moller quads to "nominal".

       Ask MCC to flip IHWP to OUT.  Ran flipper (Halog 159707).

17:00  Beam back; run spot++ to verify Moller quads.  Looks good;            see Halog 159710.

17:06  Start run 6330 with IHWP=OUT.

19:05  Noticed (way late; my bad) that the Y positions at BPMA/B

       were off from nominal values of zero.  Asked MCC to recenter

       vertically and ended run 6322 very soon after beam was

       recentered.  Also ended Compton run.  MCC confirmed that

       this position change happened near the time when the 

       Moller quads were cycled.  (The off-center positions are

       given in a Hall A Tools capture - Halog 159711:

       BPMAy=0.5 and BPMBy=0.7)

21:17  MCC runs PZT test.  End run 6334 and Compton run 12824.

21:32  PZT test is finished.  

21:35  Start profile scan/run=6335 and Compton run 12825.

21:47  Start production running again with run 6336.
