Continued taking power supply off data with any_coincs trigger as per, I
believe, Tancredi's run plan. We still saw rates near 2000 Hz @max beam
current of 90 mA, so it doesn't appear to be caused by mispositioning of the
slits. After trying to contact, Tancredi and finding him unavailable for
comment (understandably, at 1:00 am on a Friday night) we decided to continue
taking data with the same settings:
Run # #events
2436 351k
2437 452k
2438 405k
On the analysis side, Tancredi instructed us to repeat the analysis done last
night ,which I think would be Oct 31, except that there is no shift summary
for that shift. We would be happy to analyze the data if Tancredi could
elaborate a little more of what was done/needs to be done.
We also starting gathering statistics for the L/R asymmetry studies using an
eep trigger (elastic_tof10_15). The rates were almost a factor of 10 lower
~200Hz at 90 mA with this trigger. The runs are
