Abstract: A detector and methods for inspecting material on the basis of scintillator coupled by wavelength-shifting optical fiber to one or more photo-detectors, with a temporal integration of the photo-detector signal. An unpixelated volume of scintillation medium converts energy of incident penetrating radiation into scintillation light which is extracted from a scintillation light extraction region by a plurality of optical waveguides. This geometry provides for efficient and compact detectors, enabling hitherto unattainable geometries for backscatter detection and for energy discrimination of incident radiation. Additional energy-resolving transmission configurations are enabled as are skew- and misalignment compensation.

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: 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 discriminating among x-ray beams of distinct energy content. A first volume of scintillation medium converts energy of incident penetrating radiation into scintillation light which is extracted from a scintillation light extraction region by a plurality of optical waveguides that convert the scintillation light to light of a longer wavelength. An x-ray beam initially incident upon the first volume of scintillation medium and traversing the first volume is then incident on a second volume of scintillation medium. The first and second scintillation media may be separated by an absorber or one or more further volumes of scintillation medium, and may also have differential spectral sensitivities. Scintillation light from the first and second scintillation volumes is detected in respective detectors and processed to yield a measure of respective low energy and high-energy components of the incident x-ray beam.
