10.9 PULSE-SHAPE DISCRIMINATIONPulse-shape discrimination (PSD) is the name given to a process that differentiates pulses produced by different types of particles in the same detector. PSD has most common use to discriminate between pulses generated by neutrons and gammas in organic scintillators (see also Chap. 14). Measurement of the amount of light produced in organic scintillators by neutrons and gammas shows that both the differential and integral light intensities are different as functions of time. It is obvious that the pulses from neutrons and gammas have different time characteristics, and it is this property that is used as the basis for PSD.
