<p>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 (10) formed of an X-ray transmissible material. The container body (10) has one open end. A target membrane (40) is formed at an inner surface of the container body (10) for receiving electrons and emitting X-rays. A base (20) plugs the open end of the container body (10) and has terminal pins (24) extending through it. A cathode (30) is supported by the terminal pins (24) and is disposed at a central portion of the container body (10) for generating electrons. If the container body (10) is cylindrical the cathode extends along the central axis of the cylinder. If the container body is spherical, the cathode is positioned adjacent the centre. In this way, since the target membrane (40) is provided at the inner surface of the container body (10), and since all the target membrane (40) is equidistant from the cathode (30), X-rays are radiated from the extended area of the outer surface of the container body (10) and uniform radiation over a wide area results. <IMAGE></p> |
