“…Emissions of neutrons from most nuclear reactions are typically accompanied by other types of radiation including gamma rays and charged particles, all of which have larger interaction cross sections with the scintillation material than neutrons. To discriminate charged particles, one can place a charged-particle veto wall in front of the neutron detector [6] or apply an external magnetic field to deflect the charged particles [7,8] away from the neutron detectors. To distinguish neutrons and gamma rays, pulse shape discrimination (PSD) on light signals emitted by organic scintillators is commonly used.…”

Using the waveforms from a digital electronics system, an offline analysis technique on pulse shape discrimination (PSD) has been developed to improve the n-γ separation in a bar-shaped NE-213 scintillator that couples to a photomultiplier tube (PMT) at each end. The new improved method, called the "valued-assigned PSD" (VPSD), quantifies the separation between neutrons and gamma rays. Position dependence of PSD can be taken into account and automated using VPSD method. The resulting n-γ identification is much improved when compared to the traditional technique that uses the geometric mean (GM) of light outputs from both PMTs.
