  • Publication number: 20180196146
    Abstract: There is provided a scintillator array to be used for a neutron detector capable of detecting high energy neutrons with high definition and high efficiency. A scintillator array comprises a structure including a plurality of stacks layered each other. Each of the stacks has in sequence: a light reflector including ceramics or single-crystal silicon; a first film to react with a neutron incident along a direction intersecting a lamination direction of the stacks and thus emit a radiation ray; a second film including a material to reflect light; and a scintillator to emit light in response to the radiation ray. The light from the scintillator is reflected by the reflector and the second film to propagate an inside of the scintillator and thus to be led to an outside of the structure.
