Abstract: This invention involves the application of dense, metallurgically bonded deposits of tungsten and tungsten rhenium coatings onto preformed based x-ray anodes to be used as focal tracks. The coatings are applied by low pressure DC plasma spraying. The invention also includes heat treatments that further densify the as-applied coatings improving their suitability for use as focal tracks.

Abstract: Nanofocus x-ray tube, includes a target, and a device for directing an electron beam onto the target. The target includes at least one target element made of a target material for generating x-rays, the at least one target element including a nanostructure having a diameter ≦about 1000 nm. The nanostructure is formed by a microstructuring procedure on a substrate element made of a substrate material, and the target element only partly covers the substrate element. The electron beam cross-section of the x-ray tube, in use, is selected to be sufficiently larger than the cross-section of the target element, such that the electron beam always irradiates the entire surface of the target element. Still further, the substrate material may be diamond, or the substrate material may include diamond, and being doped to raise the electrical conductivity.

Abstract: A multiple wavelength X-ray source includes an electron-generating cathode and an anode with multiple target regions, each of which emits X-rays at a different characteristic wavelength in response to the electrons. The different X-ray radiation outputs are focused by different focusing sections of a focusing optic. The multiple focusing sections are in different respective locations, and each focuses its respective X-ray radiation onto a sample. The focusing sections may be side-by-side mirrors in a Kirkpatrick-Baez configuration, or in a single-bounce, doubly curved elliptical configuration.

Abstract: A plurality of high atomic number wires are sintered together to form a porous rod that is parted into porous disks which will be used as x-ray targets. A thermally conductive material is introduced into the pores of the rod, and when a stream of electrons impinges on the sintered wire target and generates x-rays, the heat generated by the impinging x-rays is removed by the thermally conductive material interspersed in the pores of the wires.
