FunctionWhen a high energy beam of particles collided with a target, it triggered thousands of events and scattered particles and photons. These were picked up by detectors, which in turn sent electrical signals (or pulses) to a wide assortment of logical devices for analysis. Logic instruments included count-registers (or scalers), which counted up the events; pulse height analyzers (PHA), which selected and sorted pulses that fit within certain sized windows; and coincidence counters, which recorded simultaneous events.
Such a device is used to delay the output of a signal by a pre-determined period of time. It doesn't change the signal, only delays when it is transmitted. Because this is a multi-channel digitizer, seven distinct signals can be delayed at the same time and by the same amount.
