• Scintillation detector
• Neutron photon discrimination
• MCNPX
• Spectrum unfolding

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.
