摘要： Provided is an anode capable of keeping the X-ray dose steady in an X-ray generating tube by preventing a crack in a connecting electrode layer, which electrically connects a target layer and an anode member. The anode includes a first bonding boundary where the connecting electrode layer, which electrically connects the target layer and the anode member, is bonded to a supporting substrate of a target, and a second bonding boundary where the connecting electrode layer is bonded to the anode member in which the connecting electrode layer is formed so that the first bonding boundary and the second bonding boundary are on the same side with respect to the connecting electrode layer.

摘要： An anode for an X-ray tube can include a ceramic body, e.g., material that includes yttrium-oxide derivatives. Upon collision with an anode, the kinetic energy of an electron beam in an X-ray tube is converted to high frequency electromagnetic waves, i.e., X-rays. An anode with a ceramic body can reduce costs and/or weight, extend the life of the anode or associated components (e.g., bearings) and simultaneously provide a high heat storage capacity.

摘要： An x-ray transmission spectrometer system to be used with a compact x-ray source to measure x-ray absorption with both high spatial and high spectral resolution. The spectrometer system comprises a compact high brightness x-ray source, an optical system with a low pass spectral filter property to focus the x-rays through an object to be examined, and a spectrometer comprising a crystal analyzer (and, in some embodiments, a mosaic crystal) to disperse the transmitted beam, and in some instances an array detector. The high brightness/high flux x-ray source may have a take-off angle between 0 and 15 degrees, and be coupled to an optical system that collects and focuses the high flux x-rays to micron-scale spots, leading to high flux density. The x-ray optical system may also act as a “low-pass” filter, allowing a predetermined bandwidth of x-rays to be observed at one time while excluding the higher harmonics.

摘要： 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.

摘要： The target includes a target layer configured to be irradiated with an electron to generate an X-ray and a support substrate configured to support the target layer. The support substrate includes a polycrystalline diamond and includes multiple structure planes having different area densities of plane orientations from one another. The target layer is supported by the support substrate at a structure plane with a smaller area density of the {101} plane than the area density of the {100} plane and the area density of the {111} plane.

摘要： A rotary X-ray anode has a support body and a focal track formed on the support body. The support body and the focal track are produced as a composite by powder metallurgy. The support body is formed from molybdenum or a molybdenum-based alloy and the focal track is formed from tungsten or a tungsten-based alloy. Here, in the conclusively heat-treated rotary X-ray anode, at least one portion of the focal track is located in a non-recrystallized and/or in a partially recrystallized structure.

摘要： Disclosed are targets for generating x-rays using electron beams and their method of fabrication. They comprise a number of microstructures fabricated from an x-ray target material arranged in close thermal contact with a substrate such that the heat is more efficiently drawn out of the x-ray target material. This allows irradiation of the x-ray generating substance with higher electron density or higher energy electrons, leading to greater x-ray brightness, without inducing damage or melting. The microstructures may comprise conventional x-ray target materials (such as tungsten) that are patterned at micron-scale dimensions on a thermally conducting substrate, such as diamond. The microstructures may have any number of geometric shapes to best generate x-rays of high brightness and efficiently disperse heat. In some embodiments, the target comprising microstructures may be incorporated into a rotating anode geometry, to enhance x-ray generation in such systems.
