Analyzing Day 73 ZDC Runs

Run 10073029

 

Triggers for this run are zdc_e60_240 and zdc_w60_240.   These triggers, in contrast to the standard zdc triggers, made no requirement for a bbc coincidence.  I have the standard phi and slat-by-slat asymmetry plots attached. 

I see an yellow beam asymmetry of 0.0185+/-0.0023.  I see an blue beam asymmetry of 0.0241+/-0.0025.  The beam polarizations were ? and ?.

 

Run 10073032

Triggers for this run are zdc_e60_420 and zdc_w60_420.  Again there is no bbq requirement.  I do not have sufficient statistics to conclude anything from this run.  Only a few thousand events per spin state in the east and west detectors.  I traced this problem not to the trigger, but to  a lot of empty trigger data files.

 

Run 10073033

Standard zdc_smd_east and zdc_smd_west triggers.  Problem with trigger files for this run, can't analyze.
