Lightguide influence on timing response of scintillation detectors

In this paper, using zero-crossing method, the neutron–gamma discrimination has been discussed to estimate the contribution of light transport on the timing characteristics of scintillation detectors. Both experimental and simulation verifications for the influence of lightguide length on the neutron–gamma discrimination quality of a 2×2 in. NE213 scintillator have been presented.

► The effect of lightguide length on the neutron–gamma discrimination quality has been studied.
► The zero-crossing method has been used for neutron–gamma discrimination measurements.
► Both Monte Carlo and experimental studies show that the discrimination quality declines as lightguide length increases.
