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.
On channel 1, the electron trigger.
On channel 2, the delayed and shaped photon signal
On channel 3, the original photon signal
