Abstract
An X-ray generation tube capable of providing gas 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 a linear cylindrical shape or a circular shape. A target membrane is formed at an entire inner surface of the container body for receiving electrons and emitting X-rays. Bases are provided at both ends of the container body and have pins. A cathode is supported by the pins and is disposed at a central axis of the container body for generating the electrons. Since the distances between any one of the points on the target membrane and the cathode are equal with respect to a cross-section or the radial direction of the container body, and since the target membrane is provided at the entire inner surface of the container body, X-rays can be radiated from the entire outer surface of the container body in a uniform manner, resulting in uniform radiation.
