A neutron spectrometer is described. The 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 and a phosphor material. The spherical core is arranged to receive photons emitted from the phosphor material of the conversion layer. The neutron detector further comprises a photodetector optically coupled to the spherical core and arranged to detect the photons emitted from the conversion layer. |
