  • Patent number: 9251992
    Abstract: The purpose of the present invention is to provide a stereo x-ray radiation device that is small and for which handling is simple. One cathode that functions as an emitter and two anodes that function as targets are disposed in a single straight-tube shaped vacuum vessel. The stereo x-ray generating device is characterized by the cathode being a cold cathode disposed in the center part of the vessel, the anodes being disposed each to one end of the vessel, and the spaces between the anodes disposed in the two ends of the vessel and the cathode being constituted such that the same can be moved closer or apart along the axial line of the vessel.

  • Publication number: 20130234582
    Abstract: In the present invention, heat dissipation is improved by extending the creepage distance in a vacuum vessel according to the size of a flange portion, without lengthening the vacuum vessel in the direction in which an electron beam is emitted. A vacuum vessel (20) in which a flange portion (20a) having a hollow portion between a cold cathode (9) and an anode (11) is formed is used. One example is a vacuum vessel (20) in which a cold cathode vessel (21) and an anode vessel (22), both cylindrically shaped, are communicated with each other and a hollow flange portion (20a) is formed between the vessels (21, 22). A focusing electrode (14) and a getter material (15), for example, are disposed in the hollow portion of the flange portion (20a). A cold cathode (9) which has a guard electrode on the outer side of the periphery of a carbon film structure (10) formed on a substrate (7) may be used. The carbon film structure (10) may be formed in the middle of an electrode surface of the substrate (7).
