A neutron detector comprises a conversion layer provided on an outer surface of a spherical core of neutron moderating material. The conversion layer comprises a neutron absorbing material, for example including lithium, and a phosphor material such as ZnS. The spherical core is receives photons emitted from the phosphor material of the conversion layer by the use of a reflecting layer. The neutron detector further comprises a photodetector optically coupled to the spherical core, which may be formed of wavelength shifting light guide material. |
