<p>A neutron detector comprises one or more neutron detector modules 20. Each comprises a neutron moderating block having a plurality of neutron detector blades 2 embedded therein. Each neutron blade is generally planar and comprises conversion layers 45a, 4b on either side of a light-guiding sheet 8. Each conversion layer comprises a mixture of a neutron absorbing material and a scintillation material. A photodetector is optically coupled to the light-guide. The modules may be arranged around a sample volume in rectangular or annular cross section, and include a second set of modules or blades surrounding the first set and sample volume.</p> |
