    摘要： Various systems are provided for a cathode of an X-ray imaging system. In one example, a shield assembly for a cathode comprises a first shield part and a second shield part, the first shield part and the second shield part spaced apart such that the first shield part and the second shield part are not in direct physical contact.

    摘要： According to one embodiment, an X-ray tube includes a cathode, an anode, a cathode hood, a first X-ray transmission window, an envelope, and a first restraining member. A second side surface of the first restraining member has a contact surface that is pressed against an inner wall surface in a first hole of the cathode hood. The first X-ray transmission window is maintained in a state of being restrained to an overlap space of a first bottom surface in the first hole by the first restraining member.

    摘要： A system for generating X-ray beams from a liquid target includes a vacuum chamber, a diamond window assembly, an electron source, a target material flow system, and an X-ray detector/imager. An electron beam from the electron source travels through the diamond window assembly and into a dynamic target material of the flow system. Preferably, the dynamic target material is lead bismuth eutectic in a liquid state. Upon colliding with the dynamic target material, X-rays are generated. The generated X-rays exit through an X-ray exit window to be captured by the X-ray detector/imager. Since the dynamic target material is constantly in fluid motion within a pipeline of the flow system, the electron beam always has a new target area which is at a controlled operational temperature and thus, prevents overheating issues. By providing a small focus area for the electron beams, the overall imaging resolution of the X-rays is also improved.

    摘要： A method is for manufacturing a multilayer radiation window for an X-ray measurement apparatus. The method includes: producing a gas diffusion stop layer made of silicon nitride on a polished surface of a carrier; producing at least one combined layer on an opposite side of the gas diffusion stop layer than the carrier; attaching the combined structure including the carrier, the gas diffusion stop layer, the at least one combined layer to a region around an opening in a support structure with the at least one combined layer facing the support structure; and etching away the carrier. The at least one combined layer includes: a light attenuation layer made of aluminium, and a strengthening layer. A radiation window is manufactured with the method.
