Abstract:
    An X-ray generating apparatus for generating X-rays by irradiating a target with an electron beam. Wherein the apparatus includes a vibration applying means for vibrating the target in directions parallel to a surface thereof. A colliding spot of the electron beam is movable on the target while maintaining an X-ray focus in the same position on the electron beam without fluctuating the X-ray focal position. This enlarges an actual area of electron collision on the target to disperse the generated heat, thereby to suppress a local temperature rise of the target due to the electron collision. The X-ray generating apparatus is compact, and has a long life and a high X-ray intensity.
