摘要：
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/gamma ratio, multi-counting rate, and neutron/gamma 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 B-10, glass scintillators containing B-10 or Li-6, Li-6-loaded plastic scintillators and organic phosphors containing B-10. The detection-characteristics of these scintillators were discussed, mainly for their detection efficiency. (C) 2004 Elsevier B.V. All rights reserved.
