Abstract : The pulse shape discriminator described employs an integrated circuit differential comparator to measure the zero cross-over time of a bi-polar pulse relative to the start of the pulse. The comparator element operates over a dynamic range of 0.02 to 10 V with a time shift of less than 4 ns for DDL pulses with a rise time of 100 ns. The pulse shape discriminator includes pile-up rejection and dead-time circuitry to reduce count rate effects. The energy dependence of the pulse shape for NE 213 and stilbene is measured from 0.2 to 4 MeV electron equivalent energy. The low energy performance for a small stilbene scintillator is studied from 18 to 92 keV electron equivalent energy. (Author)
