Abstract: Systems and methods for detecting clandestine fissile or radioactive material on the basis of emitted radiation and particles (such as neutrons and alpha particles) arising from within the material. Emission by the fissile or radioactive material is detected in conjunction with a conventional x-ray imaging system that includes an external source of illuminating penetrating radiation, at least one detector configured to detect at least the penetrating radiation and to generate a detector signal, and a processor configured as a detector signal discriminator to generate an output indicating whether the detector signal is triggered by an origin other than illuminating penetrating radiation. Active and passive modes of detection are described by some embodiments. Other embodiments are directed toward neutron detection, gamma ray detection with energy resolution, and designs of detectors to enhance the detection of clandestine nuclear material.

Abstract: An X-ray tube with an anode assembly and specially designed heat transfer element is described. The anode assembly includes an X-ray producing target and a substantially cylindrical electrode that stops or inhibits electrons that may back-scatter from the target. At least one heat transfer element is positioned proximate the anode assembly and in the region between a conducting enclosure and a non-conducting hollow housing or tube. The heat transfer element is positioned to thermally couple the hot anode assembly to an air-cooled conducting enclosure while maintaining an electric isolation.

Abstract: The present specification describes a system for synchronizing a transmission detector and a backscatter detector integrated with a portable X-ray scanner. The system includes a transmitter connected with the transmission detector for transmitting the analog detector signal and a receiver connected with the scanner for receiving the transmitted analog detected signal where the transmitter and the receiver operate in the ultra-high frequency range.

Abstract: The present specification provides a detector for an X-ray imaging system. The detector includes at least one high resolution layer having high resolution wavelength-shifting optical fibers, each fiber occupying a distinct region of the detector, at least one low resolution layer with low resolution regions, and a single segmented multi-channel photo-multiplier tube for coupling signals obtained from the high resolution fibers and the low resolution regions.

Abstract: Methods and an x-ray source for sweeping an x-ray beam across an object of inspection. A beam of electrons is emitted by a cathode, while a sweep controller applies a signal to a beam controller in a prescribed path on an anode, thereby causing an x-ray beam to be emitted from an aperture disposed at one apex of a snout of variable length. The aperture may be a Rommel aperture that allows for forming a scanning x-ray of desired size and flux independently of the angle at which the beam is emitted. Scanning rate may be varied during the course of a scan. Multiple x-ray beams may be formed simultaneously, where one beam is inside a conveyance while the other is outside the conveyance, for example.

Abstract: Methods for characterizing living plants, wherein one or more beams of penetrating radiation such as x-rays are scanned across the plant under field conditions. Compton scatter is detected from the living plant and processed to derive characteristics of the living plant such as water content, root structure, branch structure, xylem size, fruit size, fruit shape, fruit aggregate volume, cluster size and shape, fruit maturity and an image of a part of the plant. Ground water content is measured using the same technique. Compton backscatter is used to guide a robotic gripper to grasp a portion of the plant such as for harvesting a fruit.

Abstract: An X-ray cargo inspection system and method. A lead-in conveyor on a first trailer receives a cargo container for inspection. An inspection module disposed on a second trailer then scans the cargo container with penetrating radiation, detects penetrating radiation that has interacted with the cargo container, and produces an inspection signal. An exit conveyor disposed on a third trailer projects the cargo container following scanning. The inspection module may contain transmission or scatter detectors, or both. Multiple lead-in conveyors may serve to load additional cargo containers for subsequent scanning by the inspection module.

Abstract: A conveyance and methods for x-ray inspection of an object. The conveyance has a bed with attached wheels and detector elements disposed along a pontine structure coupled to the conveyance. A source of penetrating radiation is coupled to the conveyance and disposed so as to irradiate each of the detector elements from a single position. An automated manual transmission couples power from an engine to a set of the wheels of the conveyance, both for road travel and for x-ray inspection.

Abstract: Methods for generating a multiple-energy X-ray pulse. A beam of electrons is generated with an electron gun and modulated prior to injection into an accelerating structure to achieve at least a first and specified beam current amplitude over the course of respective beam current temporal profiles. A radio frequency field is applied to the accelerating structure with a specified RF field amplitude and a specified RF temporal profile. The first and second specified beam current amplitudes are injected serially, each after a specified delay, in such a manner as to achieve at least two distinct endpoint energies of electrons accelerated within the accelerating structure during a course of a single RF-pulse. The beam of electrons is accelerated by the radio frequency field within the accelerating structure to produce accelerated electrons which impinge upon a target for generating Bremsstrahlung X-rays.
