Photodiode readout and pulse shape analysis of CsI(Tl) scintillator signals

Abstract The light output performance of CsI(Tl) scintillators coupled directly or via wavelength shifters to a photodiode is investigated. Using a photodiode readout system, the zero-crossing technique of pulse shape analysis has been employed to identify gammas, neutrons and charged particles (p, d, t, α) with a low energy threshold.
