A method for manufacturing an X-ray tube that simplifies the manufacturing process, which method includes a stem unit assembly process, a high-temperature brazing process, an X-ray tube assembly process, and a low-temperature brazing process. In the stem unit assembly process, cathode pins are inserted through high-temperature brazing material and the cathode pin holes provided on the bottom plate member of the stem unit. In the high-temperature brazing process, the stem unit assembled in the above-described process is heated to the brazing temperature of the high-temperature brazing material used in the stem unit. In the X-ray tube assembly process, the focusing electrode, ceramic bulb, and output window are placed over the stem unit with low-temperature brazing material interposed between each component. In the low-temperature brazing process. the X-ray tube assembled in the above-described process Is heated to the brazing temperature of the low-temperature brazing material used in the X-ray tube assembly.

Method for manufacturing transmission type X-ray tube

To provide an X-ray generator capable of both being compact and containing an air-cooling mechanism, an X-ray generator according to the present invention houses within a protective case both an X-ray tube containing a cathode for irradiating a target with an electron beam, in which X-ray tube the target having a ground potential is fixed to the inner surface of an output window, which in turn is fixed to an electrically and thermally conductive output window support provided on the end of a bulb; and a power supply for driving the X-ray tube. A flange portion formed on the output window support so as to protrude externally contacts and is fixed to the thermally conductive protective case. As a result, heat near 100.degree. C. generated continuously in the X-ray tube is transferred to the protective case and dissipated externally. The thus configured X-ray generator is best suited when used as an electrostatic remover for removing electrostatic accumulations on an object, such as an integrated circuit.
