Abstract: An x-ray tube includes a cathode which supplies electrons that bombard a target material to produce x-rays. The target is supported on a rotating anode that includes fins covered with a high emissivity material. An envelope surrounds these elements and provides a vacuum chamber in which they operate. A receptor is mounted to the envelope and includes fins which mate with the anode fins to enhance the radiation of heat from the rotating anode. A cooling liquid is pumped through the receptor.

Abstract: A rotating anode X-ray generating tube having heat dissipating fins on the anode structure interleaved with heat receiving fins attached to the vacuum envelop with means for cooling the heat receiving fins, thereby allowing enhanced heat transfer from the anode structure to the outside environment. The operation of the foregoing structure may be enhanced further by judicious choice of materials.

Abstract: A heat radiating coating of rhenium for a refractory core which may be used for a rotating X-ray anode, power tube or the like. The coating is characterized by a multiplicity of needle-like radiation-reflecting elements disposed adjacent to each other. The needles have such steep angles that incoming radiation is substantially absorbed thereby by repeated reflection. Since the coating has a high radiation absorption coefficient it has a corresponding high emissivity on the order of 0.9 at elevated temperatures. A process is disclosed for depositing such a heat radiating coating of rhenium by chemical vapor deposition.

Abstract: An X-ray assembly may include a vacuum wall, an anode, and a cathode. The vacuum wall may define a vacuum enclosure and may include an X-ray window. The anode may be located within the vacuum enclosure. The anode may include a target area. The cathode may be located within the vacuum enclosure. The cathode may generate an electron stream to travel to a focus area located at the target area of the anode. The cathode may be positioned such that the electron stream travels along an oblique path relative a virtual line positioned so as to intersect a center of the focus area and a center of the X-ray window.

Abstract: 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.
