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: A window member for separating an internal environment of an x-ray device from an environment external to the x-ray device is provided. The window member comprises a substrate and a coating layer disposed upon a surface of the substrate. The substrate is formed from a polycrystalline material and is substantially transparent to low-energy x-rays. The coating layer is non-porous, covers the crystal grains at the surface of the substrate and extends into the grain boundaries therebetween, such that the coating layer forms an impermeable barrier between the substrate and the external environment.
