Abstract: A method and a device for determining the material properties of a polycrystalline, in particular metallic, product during production or quality control of the polycrystalline, in particular metallic, product by means of X-ray diffraction using at least one X-ray source and at least one X-ray detector. In this case, an X-ray generated by the X-ray source is directed onto a surface of the polycrystalline product and the resulting diffraction image of the X-ray is recorded by the X-ray detector. After exiting the X-ray source, the X-ray is passed through an X-ray mirror, wherein the X-ray is both monochromatized and focused, by the X-ray mirror, in the direction of the polycrystalline product and/or the X-ray detector, and then reaches a surface of the metallic product.

Abstract: An anode for an X-ray tube is provided. The anode has a shape configured such that, in use: an electron beam impinges upon the anode at a focal spot on the surface of the anode, and the anode is heated by the electron beam from a first state to a predetermined second state and undergoes resulting thermal expansion causing a change in the location of the focal spot on the surface of the anode, wherein the configured shape of the anode is such that the spatial position of the focal spot with respect to the X-ray tube is substantially the same for the first state and the second state. A method of producing an anode for an X-ray tube is also provided.

Abstract: Some embodiments include a system, comprising: at least one x-ray source, each x-ray source including: an electron source configured to generate an electron beam; and a target configured to receive the electron beam and convert the electron beam into an x-ray beam; and a collimator. A first edge of the collimator closest to the electron source is closer to the electron source than a central axis of the x-ray beam before entering the collimator; and a second edge of the collimator opposite to the first edge is at the central axis of the x-ray beam before entering the collimator or closer to the electron source than the central axis of the x-ray beam before entering the collimator.
