Pulse Processing: Pulse Shaping
The shapes of signal pulses from detectors are usually changed or shaped by the signal conditioning or processing elements of the data acquisition system. It is very common, for example, to shape the output pulses of the preamplifier in the amplifier. To assure complete charge collection from a detector, preamplifier circuits are normally adjusted to provide a long decay time for the pulse (typical decay times are on the order of 50 µs). Since the pulses occur at random times (radioactive decay is a random process) they will sometimes overlap (especially if the count rate is large)
