Neutron/γ-ray discrimination characteristics of novel neutron scintillators

We have investigated scintillators for neutron imaging detectors used in neutron scattering instruments. Three kinds of scintillators such as novel lithium–boron–phosphorus glass scintillators, Li2B4O7 glass scintillators, and a 6Li-loaded plastic scintillator are fabricated and evaluated, especially for the n/γ discrimination characteristics. Consequently, it is confirmed that the 6Li-enriched lithium–boron–phosphorus glass scintillator and the 6Li-loaded plastic scintillators have abilities for n/γ discrimination.
