keyword=Late Entry: Re: Gas Cerenkov test (5238)Late Entry:
Below is the plot of T1 rate(in "++" state only) during the run that Xin took last night(5238), turning off/on the gas Cerenkov during the run to test if there is any influence of this on the T1 rate. We can clearly see the T1 rate from one of the gated scaler(++) increases when the GC is turned on and decreases when it is off. This happens only on the L-HRS gated scalers, BB scalers show no such structure.
T6 behaves the same way on L-HRS.
