    摘要： A method and device for cooling and electrically-insulating a high-voltage, heat-generating component, for example, an x-ray tube (1105) for analyzing fluids by means of x-ray fluorescence. The device includes an x-ray source (1100) including an x-ray tube (1105) having improved heat-dissipating properties due to the thermal coupling of the x-ray tube with a thermally-conductive, dielectric material (1150). The device may include a base assembly (1135) mounted to the component for conducting heat away from the component while electrically isolating the component. In one aspect of the invention, the base assembly includes two copper plates (1140, 1145) separated by a dielectric plate (1150). The dielectric plate minimizes or prevents the leakage of current through the base assembly (1135). One aspect of the disclosed invention is most amenable to the analysis of sulfur in petroleum-based fuels.

The devices include optics having a plurality of optical crystals, for example, doubly-curved silicon or germanium crystals, arranged to optimize the capture and redirection of divergent radiation via Bragg diffraction. In one aspect, a plurality of optic crystals having varying atomic diffraction plane orientations are used to capture and focus divergent x-rays upon a target. In another aspect, a two- or three-dimensional matrix of crystals is positioned relative to an x-ray source to capture and focus divergent x-rays in three dimensions.

    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 supported in the space and streaming through the focal area, using a support structure to guide the sample stream. The chamber's barrier is therefore separated from both the focal area and the sample, resulting in lower corruption of the barrier.

    摘要： A diffracting x-ray optic for accepting and redirecting x-rays. The optic includes at least two layers, the layers having a similar or differing material composition and similar or differing crystalline orientation. Each of the layers exhibits a diffractive effect, and their collective effect provides a diffractive effect on the received x-rays. In one embodiment, the layers are silicon, and are bonded together using a silicon-on-insulator bonding technique. In another embodiment, an adhesive bonding technique may be used. The optic may be a curved, monochromating optic.
