Value-Assigned Pulse Shape Discrimination for Neutron Detectors

چکیده

Using the waveforms from a digital electronic system, an offline analysis technique on pulse shape discrimination (PSD) has been developed to improve neutron-gamma separation in bar-shaped NE-213 scintillator that couples photomultiplier tube (PMT) at each end. The new improved method, called ``valued-assigned PSD'' (VPSD), assigns normalized fitting residual every waveform as PSD value. This procedure then facilitates incorporation of longitudinal position dependence scintillator, which further enhances capability detector system. In this paper, we use radiation emitted AmBe neutron source demonstrate resulting identification much when compared traditional uses geometric mean light outputs both PMTs. method also modified and applied recent experiment National Superconducting Cyclotron Laboratory (NSCL) analog

Pulse Shape Discrimination with The Neutron Walls at NCSL

The National Superconducting Cyclotron Laboratory at Michigan State University has recently completed the Coupled Cyclotron Upgrade. The new facility will concentrate on the study of rare isotopes produced in fragmentation reactions. Neutron-rich unstable isotopes can be investigated via break-up reactions. The resulting neutrons will be detected in two walls of position sensitive detectors. Ea...

Pulse-shape Discrimination for Identification of Neutron Sources Using the Bc-501a Liquid Scintillator

Fast and accurate identification of neutron sources is very important in nuclear nonproliferation and international safeguards applications. Commonly, the identification of neutron spectra relies on unfolding procedures, which requires the solution of an ill-posed problem. In this paper, we present a new application of an existing technique, which can be used for neutron source identification w...
