    Abstract: A radiation source which can emit X-ray flux, UV-C flux and other forms of radiation uses electron beam current from a cathode array formed on the window through which the radiation will exit the source. The source can be made in formats which are compact or flat compared with prior art radiation sources. X-ray, UV-C and other radiative flux produced by the source can be used for such purposes as radiation imaging, sterilization, decontamination of biohazards, UV curing or photolithography.

    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 cathode head (200) is provide that is suitable for use in an x-ray device (100) that includes an anode (300) having a target surface (304) configured and arranged to receive electrons emitted by the cathode head (200). The cathode head (200) may be constructed of magnetic or non-magnetic material and includes an emitter structure (202) carrying a filament (204) that defines a longitudinal axis about which is disposed one or more magnetic elements such as coils (208). The filament (204) is configured and arranged to emit an electron beam that defines a focal spot on the target surface (304) of the anode (300). The magnetic coil, or coils (208), disposed about the longitudinal axis defined by the filament (204) generate a magnetic field that enables control of the location of the focal spot on the target surface of the anode.

    Abstract: An anode for an X-ray source is formed in two parts, a main part (18) and a collimating part (22). The main part (18) has the target region (20) formed on it. The two parts between them define an electron aperture (36) through which electrons pass to reach the target region (20), and an X-ray aperture through which the X-rays produced at the target leave the anode. The anode produces at least the first stage of collimation of the X-ray beam produced.

    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 10µm 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.
