    keyword=Timing Jitter Compton modified electron board

    To look at the improvement of the fixed electronics, I enabled on the
    first 16 strips of alternativly plan C and D. And look at the dispersion
    of the electron with respect to the photon signal.
    We see a clear improvement in the jitter about 300 ns for plane D which
    was modified and no delay ( the photon shaped gate was set for
    coincidence with C ).
    While on plane C the jitter is about twice as big around 500 ns.
