  • Patent number: 10859716
    Abstract: A device for determining the location of a source of radiation, based on data acquired at a single orientation of the device without iteration or rotations. Embodiments may comprise two side detector panels positioned closely parallel to each other and adjacent to each other, plus a front detector positioned orthogonally in front of the side detectors, without collimators or shields. The various detectors have contrasting angular sensitivities, so that a predetermined angular correlation function can determine the sign and magnitude of the source angle according to the detection rates of the front and side detectors. Embodiments enable rapid detection and localization of nuclear and radiological weapon materials for greatly improved inspection of cargo containers and personnel. Advanced detectors such as those disclosed herein will be needed in the coming decades to protect against clandestine weapon transport.

  • Patent number: 10830912
    Abstract: A dual or multi-energy range x-ray image sensor is implemented as side-by-side pixel arrays on a planar and monolithic semiconductor substrate as part of an x-ray object detector. Each pixel array in this side-by-side monolithic arrangement is designed to be responsive to a particular x-ray energy range or spectrum (i.e. a high-energy (HE) range or a low-energy (LE) range) to provide high object sensitivity and material discrimination capabilities. The side-by-side monolithic construction of pixel arrays improves alignment and spacing precision for improved image alignment among different arrays specialized in detecting different energy levels and signatures. Furthermore, integrated signal processing circuitry, placed on a radiation-shielded periphery of the pixel arrays, enables improved detection performance with enhanced noise reduction and/or sensitivity.

  • Patent number: 10802161
    Abstract: Disclosed is a directional gamma ray or neutron detector that locates a source both horizontally and vertically. In some embodiments, the detector comprises four “rod” scintillators around a shield, and an orthogonal “panel” scintillator mounted frontward of the rod scintillators. The azimuthal angle of the source may be calculated according to the detection rates of the rod scintillators, while the polar angle of the source may be calculated from the panel scintillator rate using a predetermined angular correlation function. Thus, the exact location of the source can be found from a single data set without iterative rotations. Embodiments of the detector enable rapid detection and precise localization of clandestine nuclear and radiological weapons in applications ranging from hand-held survey meters and walk-through portals, to vehicle cargo inspection stations and mobile area scanners. Such detectors are needed to detect clandestine nuclear weapons worldwide.
