Patent ID: 8338795

Claim:
A method for spatially resolving two or more sources of neutrons, comprising the steps of: providing a plurality of neutron detector assemblies disposed in first and second groups mounted onto a plurality of struts to form first and second plane arrays of neutron detector assemblies, wherein the plurality of struts comprising the first and second plane arrays are interconnected to form a cage, and wherein the first and second plane arrays are held in parallel alignment with respect to each other; providing a pulse discrimination module in electrical communication with each of the first and second plurality of neutron detector assemblies; providing means for moving the second plane array relative to the first plane array; moving the second plane array from the first plane array by a first separation distance; detecting two or more point sources of neutrons for a period of time interval sufficient to provide a first neutron map; increasing the separation distance by a fixed increment and repeating the step of detecting; and repeating the step of increasing the separation until the one or more neutron sources are spatially resolved.
