    Abstract: An apparatus and method for providing uniform X-Ray irradiation to material carried in a plurality of containers. The apparatus includes an X-Ray tube providing a linear source of irradiation and also a 4pi (360 degrees) irradiation. The material to be irradiated is placed in containers suspended on a vertical carousel wheel type structure. The individual containers are mounted receive irradiation throughout the rotation of the wheel. The tube is mounted approximately at the axis or center of the wheel. In operation, the containers of material are rotated around the tube, and due to their orientation and the 4 pi irradiation from the source, each and all the containers receive a uniform irradiation for the material contained therein.

    Abstract: The present invention relates to an X-ray source comprising an electron source (1) for the emission of electrons (E), a target (4) for the emission of characteristic, substantially monochromatic X-rays (C) in response to the incidence of the electrons (E) and an outcoupling means (11) for outcoupling of the X-rays. To achieve characteristic, substantially monochromatic X-rays with a high power loadability electrons are incident on a metal foil (5) of a thickness of less than 10 μm and a base arrangement (7, 12) is arranged wherein the metal of said metal foil (5) has a high atomic number allowing the generation of X-rays (C) and the material substantially included in the base arrangement (7, 12) has a low atomic number not allowing the generation of X-rays (C). The outcoupling means are adapted for outcoupling only X-rays (C) on the side of the metal foil (5) on which the electrons (E) are incident and which is opposite to the side of the base arrangement (7, 12) since on this side almost no bremsstrahlung radiation is generated.

    Abstract: In an X-ray source 1 and an X-ray tube 4, there is formed a shield portion 42 adapted to shield the portion W where a target support body 18 and an opening portion 34 on the other end side of a valve 20 are fixed to each other when viewed from the one end side of the valve 20. Therefore, the generation of discharge between the one end side of the valve 20 and the fixation portion W can be suppressed. Also, the other end portion of the valve 20 is formed as a narrowed portion 37 and the opening portion 34 on the other end side of the valve 20 is fixed to the target support body 18, whereby the shapes of the valve 20 and the shield portion 42 can be made simpler than in conventional X-ray tubes in which an inner cylindrical portion is formed in a valve. Such a simple structure can improve the stability of an electric field in the valve 20 when generating X-rays and thereby achieve an effective suppression of the generation of discharge in the valve 20.

    Abstract: An improved x-ray generation system produces a converging or diverging radiation pattern particularly suited for substantially cylindrical or spherical treatment devices. In an embodiment, the system comprises a closed or concave outer wall about a closed or concave inner wall. An electron emitter is situated on the inside surface of the outer wall, while a target film is situated on the outside surface of the inner wall. An extraction voltage at the emitter extracts electrons which are accelerated toward the inner wall by an acceleration voltage. Alternately, electron emission may be by thermionic means. Collisions of electrons with the target film causes x-ray emission, a substantial portion of which is directed through the inner wall into the space defined within. In an embodiment, the location of the emitter and target film are reversed, establishing a reflective rather than transmissive mode for convergent patterns and a transmissive mode for divergent patterns.

    Abstract: A miniature x-ray tube has an anode assembly capable of transmitting x-rays through the anode and over a wide angular range. The anode is in the shape of a cone or truncated cone with an axis on the x-ray tube frame axis, formed of low-Z material with high thermal conductivity for heat dissipation. A target material on the anode body is in a thin layer, which may be approximately 0.5 to 5 microns thick. In one embodiment a tube evacuation exhaust port at the tail end of the anode assembly forms a cavity for a getter, with a pinched-off tubulation at the end of the cavity.

    Abstract: An x-ray generating device includes a field emission cathode formed at least partially from a nanostructure-containing material having an emitted electron current density of at least 4 A/cm2. High energy conversion efficiency and compact design are achieved due to easy focusing of cold cathode emitted electrons and dramatic reduction of heating at the anode. In addition, by pulsing the field between the cathode and the gate or anode and focusing the electron beams at different anode materials, pulsed x-ray radiation with varying energy can be generated from a single device. Methods and apparatus for independent control of electron emission current and x-ray energy in x-ray tubes are also provided. The independent control can be accomplished by adjusting the distance between the cathode and anode. The independent control can also be accomplished by adjusting the temperature of the cathode. The independent control can also be accomplished by optical excitation of the cathode. The cathode can include field emissive materials such as carbon nanotubes.
