Query: Value-assigned pulse shape discrimination for neutron detectors   Using the waveforms from a digital electronic system, an offline analysis
technique on pulse shape discrimination (PSD) has been developed to improve the
neutron-gamma 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), assigns a normalized fitting residual to every
waveform as the PSD value. This procedure then facilitates the incorporation of
longitudinal position dependence of the scintillator, which further enhances
the PSD capability of the detector system. In this paper, we use radiation
emitted from an AmBe neutron source to demonstrate that the resulting
neutron-gamma identification has been much improved when compared to the
traditional technique that uses the geometric mean of light outputs from both
PMTs. The new method has also been modified and applied to a recent experiment
at the National Superconducting Cyclotron Laboratory (NSCL) that uses an analog
electronic system.
