A method, apparatus and system for profiling a material composition of a volume is disclosed. A beam source directs a pulsed beam of electromagnetic energy from into the volume. A plurality of backscattered beams is received at a detector. The plurality of backscattered beams is generated from a plurality of depths within the volume in response to interactions of the directed pulsed beam at the plurality of depths. A processor performs range gating of the plurality of backscattered beams to obtain a depth profile of backscattered intensity within the volume and estimates a material composition at different depths of the volume from the generated depth profile.

System and method for depth profiling by temporal and spatial range gating based on penetrating electromagnetic radiation

Methods and apparatus for a detector system to detect gamma and neutron radiation. In one embodiment, a detector comprises a tank to hold a liquid, a plurality of tubes adjacent the tank to detect neutrons, and a plurality of photon detectors to detect Cherenkov light generated by gamma radiation in the liquid. The tank is configured to contain the liquid so that the liquid generates the Cherenkov light and moderates the neutrons.

Methods and apparatus for integrated neutron/gamma detector

A neutron detector system including a neutron sensitive reaction layer may be configured to react with incident neutrons to form energetic particles. An energetic particle capturing layer may be configured to capture energetic particles emitted from the neutron sensitive reaction layer and convert the kinetic energy of the captured energetic particles to heat. A microbolometer sensing element responsive to the heat may be configured to detect the incident neutrons.

Neutron detection system

According to one embodiment, a system for interrogating hidden contents of a container comprises a controller, a detector system, and a data system. The controller receives a selection of a source mode of source radiation to generate to interrogate contents of a container. The source mode selection comprises a neutron mode, a gamma ray mode, or a combined neutron-gamma ray mode. The controller instructs a cyclotron to generate the source radiation according to the source mode selection. The detector system detects radiation emitted from the contents in response to the source radiation. The data system analyzes the emitted radiation and describes the contents according to the analysis.

Interrogating hidden contents of a container

According to one embodiment, generating image data includes receiving coded aperture imaging sensor data collected according to coded aperture imaging and receiving Compton imaging sensor data collected according to Compton imaging. The coded aperture imaging sensor data and the Compton imaging sensor data are generated by a sensor system sensing radiation from a radiation source. A coded aperture imaging pixel value and a Compton imaging pixel value are determined for each pixel of an image. A combining function comprising addition is applied to the coded aperture imaging pixel value and the Compton imaging pixel value to yield a combined pixel value for each pixel. Combined image data is generated from the combined pixel values. The combined image data is configured to yield a combined image of the radiation source.
