Start Counter Operations 2018Fall

Start Counter Performance Fall 2018

The gain and performance of the Start Counter paddles is rather constant over the fall of 2018 with the exception of a small period where the run conditions were quite different. This was the period with very low intensity running, 40nA of e-beam current rather than the usual 200nA. This is demonstrated by looking at the dEdx data from the start counter as a function of run number. During the low intensity running the gain was about 4% higher.
