NEUTRON BEAM DETECTOR, NEUTRON BEAM DETECTION SCINTILLATOR, AND METHOD FOR DISCRIMINATION BETWEEN NEUTRON BEAM AND Γ BEAM

摘要

Disclosed are: a neutron beam detector which comprises a material having low deliquescent properties and can discriminate between a neutron beam and a γ beam; a neutron beam detection scintillator; and a method for discriminating between a neutron beam and a γ beam.Specifically disclosed are: a neutron beam detection scintillator for use in the discrimination between a neutron beam and a γ beam based on the difference in waveforms of light detection signals, and which comprises Ce-containing LiCaAlF₆ single crystals; a neutron beam detector which has a function of discriminating between a neutron beam and a γ beam based on the difference in waveforms of light detection signals from a neutron beam detection scintillator, and which is characterized by using a neutron beam detection scintillator comprising Ce-containing LiCaAlF₆ single crystals as a neutron beam detection scintillator; and a method for discriminating between a neutron beam and a γ beam.
