T0
Studies:
Run 10920: #T0N=1 and #T0P=1
Run 10920: #T0N=1 and #T0P=1
¥What
did we learn from these studies:
¥Because of the requirement that only one
T0 counter on each side fires, crosstalk within the cable is not an effect
here.
¥Crosstalk between P and N cables is
possible, but requires that for example pair 8 in the P cable has an effect on
pair 0 on the N cable.
¥The widths of the vertex difference
distributions are narrow and correspond to a collision time resolution of 100
ps (uncorrected).
¥All these events can be used, but we need
10 different sets of calibration constants.
