Abstract: The present invention provides a Time-of-Flight based neutron inspection system. The system employs a collimated beam of fast neutrons for targeted interrogation of suspect areas in cargo. Elemental composition is determined as a function of depth. Analysis is then used to determine the presence of contraband. The system may be used for secondary inspection for material discrimination to reduce false alarm rate and high cost and time associated with manual unpacking.

Abstract: The present specification discloses a covert mobile inspection vehicle with a backscatter X-ray scanning system that has an X-ray source and detectors for obtaining a radiographic image of an object outside the vehicle. The system is configured to also simultaneously detect passive radiation. The systems preferably include at least one sensor for determining a distance from at least one of the detectors to points on the surface of the object being scanned, a processor for processing the obtained radiographic image by using the determined distance of the object to obtain an atomic number of each material contained in the object, and one or more sensors to obtain surveillance data from a predefined area surrounding the vehicle.

Abstract: The present application discloses a system for scanning a shoe for illegal materials. The system includes an X-ray source for projecting a beam of X-rays onto the shoe, a detector array for detecting X-rays transmitted through the shoe and at least one metal detector coil for detecting metals within the shoe. The system produces a radiographic image of the shoe by processing the detected X-rays and data obtained from the at least one metal detector coil. Other embodiments are directed toward other screening technologies, including millimeter wave screening technologies.

Abstract: The present invention provides a multi-view X-ray inspection system. In one embodiment, a beam steering mechanism directs the electron beam from an X-ray source to multiple production targets which generate X-rays for scanning which are subsequently detected by a plurality of detectors to produce multiple image slices (views). The system is adapted for use in CT systems. In one embodiment of a CT system, the X-ray source and detectors rotate around the object covering an angle sufficient for reconstructing a CT image and then reverse to rotate around the object in the opposite direction. The inspection system, in any configuration, can be deployed inside a vehicle for use as a mobile detection system.

Abstract: The present invention provides a gamma-neutron detector based on mixtures of thermal neutron absorbers that produce heavy-particle emission following thermal capture. The detector consists of one or more thin screens embedded in transparent hydrogenous light guides, which also serve as a neutron moderator. The emitted particles interact with the scintillator screen and produce a high light output, which is collected by the light guides into a photomultiplier tube and produces a signal from which the neutrons are counted. Simultaneous gamma-ray detection is provided by replacing the light guide material with a plastic scintillator. The plastic scintillator serves as the gamma-ray detector, moderator and light guide. The neutrons and gamma -ray events are separated employing Pulse-Shape Discrimination (PSD). The detector can be used in several scanning configurations including portal, drive -through, drive -by, handheld and backpack, etc.
