Quick Summary

detector output connected to a measuring circuit
detector output connected to a measuring circuit Figure 1: (A) A simple equivalent circuit for the development of a voltage pulse at the output of a detector. R represents the resistance and C the capacitance of the circuit; V(t) is the time (t)-dependent voltage produced. (B) A representative current pulse due to the interaction of a single quantum in the detector. The total charge Q is obtained by integrating the area of the current, i(t), over the collection time, tc. (C) The resulting voltage pulse that is developed across the circuit of (A) for the case of a long circuit time constant. The amplitude (Vmax) of the pulse is equal to the charge Q divided by the capacitance C.

In physics, "pulse mode" refers to a method of operation for detectors, particularly those used in radiation measurement. In this mode, a distinct electrical pulse is generated for each individual quantum of radiation that interacts with the detector. This allows for the study of the properties of individual radiation quanta.1

The process involves the liberation of charge within the detector material when radiation interacts with it. This charge is collected over a short period, creating a current burst. In pulse mode, each burst is treated as a separate event, producing a voltage pulse. The amplitude of this pulse is proportional to the amount of charge collected, which in turn relates to the energy deposited by the radiation quantum. This technique is crucial when information about individual radiation events is needed, as opposed to the collective effect of many quanta.1
