Neutron–photon discrimination and spectrum unfolding with a stilbene detector

Abstract: As a first step into the development of a neutron dose monitor, a stilbene detector is used to test a procedure applicable to other organic scintillators allowing for neutron–photon discrimination. The pulses are measured by numerical acquisition and their amplitude and decay time are calculated by software. The discrimination is performed in an amplitude-decay time plot, and separate amplitude spectra are built. These spectra are unfolded MAXED, using the detector response matrices calculated with MCNPX. [Copyright &y& Elsevier]
