Claim:
1. An X-ray generator, comprising: a vacuum chamber having an X-ray emitting window with which a target is integrated; and an electron source and a group of electrodes provided within the vacuum chamber, wherein each electrode has a predetermined potential difference relative to the electron source or the vacuum chamber so that electrons from said electron source are accelerated and converged by an electrical field created within the vacuum chamber so as to irradiate said target, and thus, X-rays can be generated so as to be taken out to the outside through said X-ray emitting window, characterized in that a portion of said vacuum chamber including said emitting window is linked to a main body portion of the vacuum chamber through a linking member so as to be movable, and an anode having a hole through which electrons transmit and having the same potential as the vacuum chamber is provided between the electrode at a final stage of said group of electrodes and said target within said vacuum chamber in such a state as to be fixed to the main body portion of the vacuum chamber.
