keyword=Deadtime loss from runs 14237-14238
Loss of tagger has been extracted and the estimated deadtime in ns w.r.t.
to various rates were calculated. Looks like after the access today, the
T1 deadtime is gone. The narrow and wide path still do not show very
clear deadtime: not 60 and 100ns, no big difference between narrow and
wide. But with the T1 deadtime gone, now the loss of each group is way
below 1%, which is a good news.
Run 14237, 50uA
total tagger count is 115171
