Abstract:
1. A neutron source detector for detecting and determining an energy spectrum of a neutron source and a direction to the neutron source, said neutron source detector comprising: a detection system configured to detect and record the location and energy of interaction between a detector and a recoil proton produced by a scattering of a neutron emitted by the neutron source; a processor configured to: determine the energy of each of a plurality of recoil protons produced by respective scatterings of a neutron based on the recorded locations and energies of interactions between said detector and the plurality of recoil protons, determine and order scatter locations of the scattered neutron based on the determined energies of the recoil protons, determine a direction of the scattered neutron based on the order of the scatter locations, determine the direction to the neutron source based on the determined directions of a plurality of scattered neutrons, and determine the energy spectrum of the neutron source based on the determined direction to the neutron source, the determined directions of the plurality of scattered neutrons, and the determined energies of the plurality of recoil protons produced by the respective plurality of scattered neutrons.
