Coincidence Resolution. The incoming pulse widths can be set using the scope and the delay-curve will give you the actual resolution as well as the rate of accidentals. In the situations you have in the lab the accidental rates will be very low but in an accelerator beam where the particles may come in bunches of very short duration or a collider experiment where interactions occur at very high rates this can be quite a problem. How many particles per collider beam crossing can your coincidence arrangement handle? What would be the accidental rate?
