    Abstract: A system and method for scanning objects using a non-translational x-ray diffraction (XRD) system is disclosed. The system includes a scanning area through which an object to be scanned traverses and a distributed x-ray source having a plurality of focal spot locations. The distributed x-ray source is affixed on the scanning area and is configured to emit x-rays towards the object as a series of parallel x-ray beams. A stationary detector arrangement is affixed on another side of the scanning area generally opposite the distributed x-ray source and is configured to measure a coherent scatter spectra of the x-rays after passing through the object. A data acquisition system (DAS) is connected to the detector arrangement and is configured to measure the coherent scatter spectra, which is utilized to generate XRD data and determine a material composition of at least a portion of the object from the XRD data.

    Abstract: A primary collimator for a multiple inverse fan beam x-ray diffraction imaging (MIFB XDI) system. The MIFB XDI system includes a multi-focus x-ray source (MFXS) defining a plurality of focus points arranged along a length of the MFXS. Each focus point is sequentially activated to emit an x-ray fan beam including a plurality of primary beams each directed to a corresponding convergence point. The primary collimator includes a first diaphragm configured to be positioned with respect to the MFXS. The first diaphragm defines a plurality of first channels through a thickness of the first diaphragm. Each first channel is aligned with a corresponding focus point and configured to transmit the x-ray fan beam. A second diaphragm is positioned with respect to the first diaphragm and defines a plurality of second channels through a thickness of the second diaphragm. Each second channel is axially aligned with a corresponding first channel.

    Abstract: System and method for XRD-based threat detection. An object is scanned with a first threat detection system. One or more alarm objects are identified. Data about the one or more alarm objects is passed from the first threat detection system to a second threat detection system and is used to move and/or to rotate the object in a predetermined ray path that decreases attenuation of scattered x-ray radiation. Also disclosed is a secondary collimator for XRD-based false alarm resolution in computed tomography {“CT”) threat detection systems. The secondary collimator comprises one or more slit apertures configured to provide a multi-angle capability that extends a range of momenta for which XRD intensities are measured for a predetermined range of photon intensities.

    Abstract: The present invention relates to an X-ray source for the generation of fluorescent X-rays. The X-ray source is realized by an electron source for the emission of electrons and a target which emits X-rays in response to the incidence of the electrons, the target comprising a ring-shaped primary target for the emission of primary X-rays in response to the incidence of the electrons and a secondary target for the emission of fluorescent X-rays in response to the incidence of the primary X-rays. To obtain an enhanced radiance, it is proposed that the primary target comprises a liquid metal channel arranged in a radial direction relative to a central axis, and that a liquid metal circulates in the liquid metal channel during operation of the X-ray source in the radial direction from an inner side to an outer side of the ring-shaped primary target.
