Scintillation materials for neutron imaging detectors

We have researched scintillation materials for neutron imaging detectors with a photon counting method. The aim of the research was to develop optimal scintillators, which have the well-balanced performances in detection efficiency, counting rate, n/γ ratio, multi-counting rate, and neutron/γ ratio for neutron scattering equipments using high-intensity pulsed neutron sources. The following scintillation materials were researched: ZnS-series phosphors with neutron converters, short-life-time phosphors with neutron converters, short-life-time phosphors containing 10B, glass scintillators containing 10B or 6Li, 6Li-loaded plastic scintillators and organic phosphors containing 10B. The detection-characteristics of these scintillators were discussed, mainly for their detection efficiency.
