T0 Time Resolution
¥The
lack of prompt T0s for collision events has a number of consequences:
¥The T0 vertex resolution does not improve
when the multiplicity of the event increases.
¥The collision time resolution does not
improve when the multiplicity of the event increases.
¥The only approach we can take in selecting
the prompt T0 counter is to take the first T0 counter that fires in a
particular event.
¥The expected collision time resolution for
prompt T0 counters is 75 ps. But
É. Contribution of non-prompt hits must be take into consideration.
