    keyword=Double Pulsing

    As per Bob Michaels request I checked to see if the triggers that we were seeing coming in between helicity flips were double pulsing or some sort of jitter.

    Indeed they are. A physical event must be ~100 clock ticks apart, after looking at the time stamps it seems that we are seeing events acomnig ~30 clock ticks apart.

    These events can be flagged, and it doesn't seem that we are missing real physics events (looking at the helicity and the flipping).

    It seems as though we have a "dirty" trigger.
