    keyword=deadtime puzzle

    We are puzzled by the high deadtime (40%) from the Carbon target
    run (4391) that we just did.

    We had the prescales such that we had only about
    650 Hz trigger rate (from T3; with just a handful of events per
    second from the other triggers), and yet the deadtime was 40%.
    Are the events particularly large?

    Comparing this with a previous C target run (at a different kinematics), run 3829, where the deadtime was 26% with about 1 kHz trigger rate, we are puzzled.

    The RC (Ramesh) says to proceed nonetheless to hydrogen production,
    so that's what we will do.
