Abstract
An X-ray generation tube capable of providing ionization to ambient atmosphere in a wide area by radiating X-rays in various directions. The X-ray generation tube includes a container body formed of an X-ray transmittable material. The container body has one open end. A target membrane is formed at an inner surface of the container body for receiving electrons and emitting X-rays. A base plugs the open end of the container body and has pins. A cathode is supported by the pins and is disposed at a central portion of the container body for generating the electrons. If the container body has an elongated cylindrical shape, the cathode is positioned at and extends along a central axis of the cylinder. If the container body has a spherical shape, the cathode is positioned adjacent to a spherical center. Since the target membrane is provided at substantially all inner surfaces of the container body, and since the distances between any one of the points on the target membrane and the cathode are the same, X-rays can be radiated from the outer surface of the container body and directed toward an extended region in a uniform manner, resulting in a uniform radiation.
