    Abstract: An x-ray tube includes a target on which electrons impinge to form a diverging x-ray beam. The target has a surface formed from first and second target materials, each tailored to emit a respective x-ray energy profile. A first x-ray optic may be provided for directing the beam toward the sample spot, the first x-ray optic monochromating the diverging x-ray beam to a first energy from the energy emitted by the first target material; and a second x-ray optic may be provided, for directing the beam toward the sample spot, the second x-ray optic monochromating the diverging x-ray beam to a second energy from the energy emitted by the second target material. Fluorescence from the sample spot induced by the first and second monochromated energies is used to measure the concentration of at least one element in the sample, or separately measure elements in a coating and underlying substrate.

    Abstract: A compact source for high brightness x-ray generation is disclosed. The higher brightness is achieved through electron beam bombardment of multiple regions aligned with each other to achieve a linear accumulation of x-rays. This may be achieved by aligning discrete x-ray sub-sources, or through the use of x-ray targets that comprise microstructures of x-ray generating materials fabricated in close thermal contact with a substrate with high thermal conductivity. This allows heat to be more efficiently drawn out of the x-ray generating material, and in turn allows bombardment of the x-ray generating material with higher electron density and/or higher energy electrons, leading to greater x-ray brightness.Some embodiments of the invention comprise x-ray optical elements placed between sub-sources of x-rays. These x-ray optical elements may form images of one or more x-ray sub-sources in alignment with other x-ray sub-sources, and may enhance the linear accumulation that can be achieved.

    Abstract: An inspection system for scanning cargo and vehicles is described which employs an X-ray source that includes an electron beam generator, for generating an electron beam; an accelerator for accelerating said electron beam in a first direction; and, a first set of magnetic elements for transporting said electron beam into a magnetic field created by a second set of magnetic elements, wherein the magnetic field created by said second set of magnetic elements causes said electron beam to strike a target such that the target substantially only generates X-rays focused toward a high density section in the scanned object, which is estimated in a second pulse using image data captured by a detector array in a first pulse. The electron beam direction is optimized by said X-ray source during said second pulse to focus X-rays towards said high density section based on said image data in said first pulse.
