Claim One:
1. A system for detecting neutron radiation, comprising: a neutron detector array comprising: a two-dimensional array of microbolometer detectors comprising sensing elements responsive to heat; a plurality of particle capture layers, each particle capture layer coupled to a different microbolometer detector of the two-dimensional array of microbolometer detectors, each particle capture layer configured to capture energetic particles and convert kinetic energy from the energetic particles to heat; a plurality of neutron sensitive layers, each neutron sensitive layer coupled to a different particle capture layer and configured to react with incident neutrons to form energetic particles; and a plurality of heat barriers, each heat barrier coupled to a different neutron sensitive layer and configured to reflect at least a portion of incident radiant heat; a readout circuit coupled to the neutron detector array, the readout circuit configured to generate a plurality of response values from the two-dimensional array of microbolometer detectors; and a processor coupled to the readout circuit, the processor configured to: generate a comparison value based on the plurality of response values and a baseline response value; and determine whether more than a first threshold amount of neutron radiation has been detected by the neutron detector array.
