    摘要： An x-ray fluorescence system and method of fabrication are provided which include a titanium x-ray source, a focusing, doubly-curved lithium fluoride (LiF) crystal optic, and a detector. The titanium x-ray source includes a titanium target on which electrons impinge to generate a diverging x-ray beam with a titanium-based characteristic energy, and the focusing, doubly-curved LiF crystal optic monochromates and focuses the diverging x-ray beam from the titanium x-ray source to provide a monochromated and focused x-ray excitation beam directed to impinge on a sample. The crystal optic and the titanium x-ray source operate at a Bragg angle which facilitates polarization within the x-ray fluorescence system. The detector receives fluorescence from the sample induced by the x-ray excitation beam impinging thereon, with the fluorescence is indicative of a concentration of at least one element in the sample.

    摘要： An x-ray analysis apparatus for illuminating a sample spot with an x-ray beam. An x-ray tube is provided having a source spot from which a diverging x-ray beam is produced having a characteristic first energy, and bremsstrahlung energy; a first x-ray optic receives the diverging x-ray beam and directs the beam toward the sample spot, while monochromating the beam; and a second x-ray optic receives the diverging x-ray beam and directs the beam toward the sample spot, while monochromating the beam to a second energy. The first x-ray optic may monochromate characteristic energy from the source spot, and the second x-ray optic may monochromate bremsstrahlung energy from the source spot. The x-ray optics may be curved diffracting optics, for receiving the diverging x-ray beam from the x-ray tube and focusing the beam at the sample spot. Detection is also provided to detect and measure various toxins in, e.g., manufactured products including toys and electronics.

    摘要： A handheld x-ray analyzer, having an outer shell forming an inner cavity, the outer shell having at least one aperture; an x-ray engine positioned within the cavity; and a generally planar heat sink rigidly and thermally attached to the x-ray engine, and positioned in the aperture of the outer shell thereby substantially filling the aperture while providing thermal conduction between the engine and surrounding air. An outer face of the heat sink may be substantially conformal with the outer shell along one or both sides of the analyzer, and form a substantial portion of one or both sides of the analyzer. Longitudinal fins may be placed on an outer face of the heat sink to aid in thermal conduction from the engine to the surrounding air. Thermal handling, shock/vibration isolation, and moisture barriers are provided.

    摘要： An x-ray analysis system with an x-ray source for producing an x-ray excitation beam directed toward an x-ray analysis focal area; and a sample chamber for presenting a fluid sample to the x-ray analysis focal area. The x-ray excitation beam is generated by an x-ray engine and passes through an x-ray transparent barrier on a wall of the chamber, to define an analysis focal area within space defined by the chamber. The fluid sample is presented as a stream suspended in the space and streaming through the focal area, using a laminar air flow and/or pressure to define the stream. The chamber's barrier is therefore separated from both the focal area and the sample, resulting in lower corruption of the barrier.
