Abstract
A neutron detector comprises one or more neutron detector modules (20). Each neutron detector module (20) comprises a neutron moderating block (22) having a plurality of neutron detector blades (2) embedded therein. Each neutron detector blade (2) is generally planar and comprises conversion layers on either side of a light-guiding sheet (8). Each conversion layer (4a, 4b) comprises a mixture of a neutron absorbing material and a scintillation material. This light-guiding sheet (8) is arranged to receive photons emitted from the scintillation material. A photodetector (10) is optically coupled to the light-guide (8) and arranged to detect photons generated in the conversion layers (4a, 4b) as a result of neutron absorption events and received into the light-guiding sheet (8).
