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).

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.

摘要： An x-ray fluorescence technique for determining a valence state of a sample. An x-ray excitation path is provided for exciting a sample with x-rays; and an x-ray detection path is provided for detecting fluorescence emitted from the sample, and focusing the emitted fluorescence to a focal spot. The detection path may include a monochromating detection optic for focusing the fluorescence; and also may include a detector on which the focal spot is focused. The precise positions of the focal spot are sensed, from which valence states of the sample can be determined; and/or the detection optic can be rocked across certain angles of incidence, to change the Bragg conditions, thereby sensing different valence states within the sample.

摘要： An x-ray system or method for exciting a sample under x-ray analysis, using a curved monochromating optic for directing a monochromatic x-ray beam from an x-ray source towards a first focal area. A second optic is positioned within, and receives, the monochromatic x-ray beam, and directs a focused x-ray beam towards a second focal area on the sample. A detector is positioned near the sample to collect radiation from the sample as a result of the focused x-ray beam. The curved monochromating optic produces a beam spot size at the first focal area larger than a beam spot size produced by the second optic at the second focal area, therefore, a beam spot size on the sample is thereby reduced using the second optic. Doubly-curved monochromating optics, and polycapillary optics, are disclosed as possible implementations of the optics.
