¥The collision time depends on the average between the
time of T0N and T0P: tcol =
(T0N + T0P)/2 - distance/c.
¥
¥Based on the observed resolution in the time
difference spectra we expect that the time resolution of prompt-prompt T0
coincidences is 75 ps.
¥
¥But we do not have any way of determining whether the
first hit is a prompt hit.
We need to understand how this will contaminate the time spectra.
