Abstract: An x-ray source has multiple electron sources spaced apart from each other along a longitudinal direction that is defined as being parallel to the rotation axis of a rotating anode which is common to all of the electron sources. Each electron source emits electrons that strike the anode at respective strike points that are spatially separated from each other along the longitudinal direction, to produce respective emission centers, from which x-rays are emitted, each emission center being associated with respective ones of the x-ray sources.

Abstract: A high energy radiation generator utilizes sliding friction in a low pressure environment to generate high energy radiation, for example x-rays. The sliding friction may be generated by sweeping one material against a second material, for example rotating a surface of a rotor against a membrane, in the presence of an electron target, which may be one of the first material or the second material, or a different material.

Abstract: An X-ray tube comprises a containment element (2) in which a cathode (4) and an anode (5) are mounted. The anode (5) comprises a first main face (6) which is substantially facing towards the cathode (4) and a second main face (7) which is facing the opposite way to the first face (6). There are also cooling means (8) applied to the second main face (7) of the anode (5) and filter means (10) for filtering, based on respective wavelengths, the X-rays emitted by the anode (5). The cooling means (8) and the filter means (10) both consist of a heat conductor element (9) which is thermally coupled with the second face (7) of the anode (5) and which is equipped with a plurality of inner micro-channels in which, in practice, a pressurised coolant liquid can flow with a turbulent motion. The containment element also comprises an X-ray emission section (3) positioned in such a way that, in practice, it receives the X-rays emitted from the second main face (7) of the anode (5) after they have passed through the filter means (10).

Abstract: Described is an X-ray rotating anode plate having a base and X-ray active layer having the described acceptable properties and a method for producing same. The base comprises carbon nanoparticles in quasi-homogeneous spatial distribution. Carbon nanoparticles can be selected from among carbon nanotubes, nano-graphite powder particles having a substantially spherical shape, and mixtures thereof. The inclusion of described additives improves the stability and heat conductivity of the base. With the described method, the starting materials for the base and X-ray active layer, and other optional materials which may form functional layer are compressed to a preselected shape in a pressing mold with simultaneous application of pressure, elevated temperature and varied electric currents, compressing the shape to a final density exhibiting high-strength diffusion bonds between these starting materials. The described X-ray rotating anode plate can be used, for example, in high-performance X-ray tubes for X-ray computer tomography.

Abstract: The present invention refers to X-ray tubes of the rotary-anode type for generating a fan beam of X-rays. More particularly, the invention is concerned with a system and method for compensating a class of system-related disturbances of the focal spot position FS on a target area AT of the rotating anode RA and particularly for compensating the anode wobble in an X-ray tube XT of the aforementioned type, which occurs as a periodically wobbling inclination angle of the anode disk's rotational plane with respect to an ideal rotational plane (z=0) which is oriented normal to the rotational axis z of the rotary shaft S on which the anode disk RA is inclinedly mounted due to an inaccuracy during its production process. For this purpose, the electron beam generated by a thermoionic or other type of electron emitter of the tube's cathode C and thus the focal spot position FS on a target area AT of the anode disk's X-ray generating surface (anode target) are steered such that the focal spot FS stays within the plane PCXB of the central X-ray fan beam CXB.

Abstract: A rotating anticathode X-ray generating apparatus which is configured such that an X-ray is generated by an irradiation of an electron beam emitted from a cathode includes a rotating anticathode with an electron beam irradiating portion to generate the X-ray through the irradiation of the electron beam so that a direction of the electron beam is set equal to a direction of a centrifugal force caused by a rotation of the rotating anticathode; and a film for covering at least the electron beam irradiating portion so as to prevent an evaporation of a material making the rotating anticathode.
