    keyword=Timing peak in Pb run 1786

    t1 timing peak for run 1786, with and without PID cuts (beyond the trigger).

    The total T6 trigger rate was about 90 Hz; I estimate that there are about 8000 events in the peak out of 68000 T6 events analyzed, so about 10Hz true coincidence rate. This is obviously preliminary!

    This true coincidence rate is comparable to the 60uA Ta run 1780; perhaps we could go to higher current on Pb and rely on offline rejection.
