| description | PROBLEM TO BE SOLVED: To provide a neutron detector capable of detecting neutrons with high-precision and high efficiency with respect to wide energy of a neutron, especially with respect to high energy thereof.SOLUTION: A neutron detector includes: a multi-stage laminated layer structure laminated with multiple stages of laminated layer structures; and a detecting section constituted so as to guide light generated by a scintillator layer outside by transmitting the light through the scintillator layer while reflecting the light by a metal film and a second vapor deposition film. Each of the laminated layer structures includes: the metal film that extends in an incident direction of a neutron and has a function as a reflecting layer for reflecting light; a first vapor deposition film that is formed on the metal film, extends in the incident direction of the neutron, reacts with neutrons and emits radioactive rays; the second vapor deposition film that extends in the incident direction of the neutron, is arranged adjacent to the first vapor deposition film and is composed of a reflecting material for reflecting light; and the scintillator layer that extends in the incident direction of the neutron, is arranged adjacent to the second vapor deposition film and generates the light from the radioactive rays generated by the first vapor deposition film. |
