NEUTRON MONITOR DEVICE AND NEUTRON MEASUREMENT METHOD

摘要

Provided are a neutron monitor device and a neutron measurement method which make it easier to measure the intensity of the neutrons having the energy region of 10 KeV to several hundreds KeV. A neutron monitor device includes a first detector which includes a hemispherical first body formed of PE and having a radius of 31 mm, a first specimen containing GaN disposed at the center of the first body, a Cd layer provided on an outer surface of the first body, and a B layer provided inside the first body, and a second detector which includes a hemispherical second body formed of PE and having a radius of 27 mm, a second specimen containing GaN disposed at the center of the second body, a B layer provided on the outer surface of the second body, and a Cd layer provided inside the second body.

1. A neutron monitor device comprising:
a first detector which includes a first body including a spherical portion of a predetermined radius formed of a hydrogen-containing material, a first specimen containing Ga disposed at the center of the spherical portion, a Cd layer provided on an outer surface of the spherical portion, and a B layer provided around the first specimen; and a second detector which includes a second body that is formed of a hydrogen-containing material and includes a spherical portion having a radius different from the radius of the spherical portion of the first detector, a second specimen containing Ga disposed at the center of the spherical portion, a B layer provided on the outer surface of the spherical portion, and a Cd layer provided around the second specimen.
