¥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.
