Particle pulse shape discrimination on a silicon surface barrier detector irradiated with 14 MeV neutrons

Abstract Based on two kinds of zero-crossing electronic setups, the particle pulse shape discrimination (PSD) test of a silicon surface barrier (SSB) detector, which was irradiated with 14 MeV neutrons from a d–T reaction, was performed. Good separation between alphas and protons has been achieved. Discrimination thresholds were estimated to be about 3 MeV. The result is comparable with the previous reports, as well as the dynamic range of the two methods discussed in this paper. This work is helpful to use SSB detectors for measuring mixed charged particles spectra induced by neutrons or charged particles.
