    Abstract: There is provided an anode stack for cooling and electrically insulating a high voltage anode of an X-ray device. The anode stack has at least a conductor member and a dielectric member, and the conductor member has a main body and a peripheral portion. The dielectric member overlies and couples with the main body of the conductor member at one surface. At an opposing surface of the main body of the conductor member, an end of the high voltage anode is coupled thereto in use. The peripheral portion of the conductor member has an annular region that surrounds at least a part of the dielectric member and which is spaced therefrom.

    Abstract: This disclosure presents systems for total reflection x-ray fluorescence measurements that have x-ray flux and x-ray flux density several orders of magnitude greater than existing x-ray technologies. These may therefore useful for applications such as trace element detection and/or for total-reflection fluorescence analysis. The higher brightness is achieved in part by using designs for x-ray targets that comprise a number of microstructures of one or more selected x-ray generating materials fabricated in close thermal contact with a substrate having high thermal conductivity. This allows for bombardment of the targets with higher electron density or higher energy electrons, which leads to greater x-ray brightness and therefore greater x-ray flux. The high brightness/high flux source may then be coupled to an x-ray reflecting optical system, which can focus the high flux x-rays to a spots that can be as small as one micron, leading to high flux density.

    Abstract: We present a micro-x-ray fluorescence (XRF) system having a high-brightness x-ray illumination system with high x-ray flux and high flux density. The higher brightness is achieved in part by using x-ray target designs that comprise a number of microstructures of x-ray generating materials fabricated in close thermal contact with a substrate having high thermal conductivity. This allows for bombardment of the targets with higher electron density or higher energy electrons, which leads to greater x-ray flux. The high brightness/high flux x-ray source may then be coupled to an x-ray optical system, which can collect and focus the high flux x-rays to spots that can be as small as one micron, leading to high flux density at the fluorescent sample. Such systems may be useful for a variety of applications, including mineralogy, trace element detection, structure and composition analysis, metrology, as well as forensic science and diagnostic systems.

    Abstract: A composite target is provided and is interacted with an electron to generate an X-ray, and an energy of the electron can be changed by controlling a tube voltage at least. The composite target includes a target body and an interposing layer which is connected with the target body. The interposing layer moves a highest peak of an energy spectrum of the X-ray toward a high energy direction. The interposing layer may be a single metal or a metal mixture. Not only a low energy photon of the X-ray can be filtered by the interposing layer, but also a distribution of the low energy photon of the X-ray can be increased by increasing a thickness of the interposing layer. As the tube voltage is enhanced, an amount of a high energy photon of the X-ray generated is dramatically increased. An X-ray tube containing the above composite target is also provided.

    Abstract: X-ray sources and production of X-rays, in particular, producing monochromatic x-rays is provided. More specifically, a method for producing X-rays and the use of the X-ray source for x-raying bodies (for example human bodies). An aerogel, for example in the form of a rod, may be provided in a housing as a target. Said target may be bombarded with an electron beam, the aerogel being vaporized due to the extreme low density and the high energy. As a result, the target is guided by means of a roller such that an unused target for producing, in particular, the monochromatic X-rays, is always available.

    Abstract: An x-ray transmission device includes two surfaces in frictional contact within a low fluid pressure environment provided by a housing substantially opaque to x-rays. Materials of the two surfaces are selected such that the frictional contact generates relative charging between the surfaces. The housing includes a window substantially transparent to x-rays, and an electron target, for example a metal, is on an interior surface of the window. The electron target faces the surface that is relatively negatively charged, such that electrons accelerated from that surface, or accelerated due to the negative charge of that surface strike the electron target to generate x-rays, which may be transmitted through the window.
