| Abstract: | Technologies related to determining elemental composition of a sample
that comprises fissile material are described herein. In a general
embodiment, a pulsed neutron generator periodically emits bursts of
neutrons, and is synchronized with an analyzer circuit. The bursts of
neutrons are used to interrogate the sample, and the sample outputs gamma
rays based upon the neutrons impacting the sample. A detector outputs
pulses based upon the gamma rays impinging upon the material of the
detector, and the analyzer circuit assigns the pulses to temporally-based
bins based upon the analyzer circuit being synchronized with the pulsed
neutron generator. A computing device outputs data that is indicative of
elemental composition of the sample based upon the binned pulses. |
