    摘要: An x-ray diffraction technique (apparatus, method and program products) for measuring crystal structure from a large sample area. The measurements are carried out using a large size collimating optic (up to 25 mm or more in diameter or corresponding cross-section) along with a 2-dimensional x-ray image detector. The unique characteristics of polycapillary collimating optics enable an efficient x-ray diffraction system (either low power or high power) to measure a large portion (or even the whole sample surface area) of the sample to obtain critical crystal structure information, such as the orientation of the whole sample, defects in the crystal, the presence of a secondary crystal, etc. Real-time, visual monitoring of the detected diffraction patterns is also provided. Turbine blade crystal structure measurement examples are disclosed.

    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.

    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.

    摘要: An x-ray diffraction technique for measuring a known characteristic of a sample of a material in an in-situ state. The technique includes using an x-ray source for emitting substantially divergent x-ray radiation—with a collimating optic disposed with respect to the fixed source for producing a substantially parallel beam of x-ray radiation by receiving and redirecting the divergent paths of the divergent x-ray radiation. A first x-ray detector collects radiation diffracted from the sample; wherein the source and detector are fixed, during operation thereof, in position relative to each other and in at least one dimension relative to the sample according to a-priori knowledge about the known characteristic of the sample. A second x-ray detector may be fixed relative to the first x-ray detector according to the a-priori knowledge about the known characteristic of the sample, especially in a phase monitoring embodiment of the present invention.
