Abstract: An X-ray generator including a cathode, an anode provided with two X-ray generation zones, a casing in which the cathode and anode are accommodated, two air cylinders for causing the anode to move, two linear guides for guiding the movement of the anode, and a bellows serving as a seal member. The air cylinders and the linear guides are provided at different positions on a surface orthogonal to a center axis of the bellows. The air cylinders and the linear guides are provided uniformly in relation to the center axis.

Abstract: Provided is an X-ray generator having: an anode that faces a cathode which generates electrons; a plurality of X-ray generation zones; a casing housing the cathode and the anode; an anode support body for supporting the anode; an air cylinder for producing advancing and retreating movement of the anode support body with respect to the casing; and a stopper device that halts the movement of the anode support body when the anode support body moves in a direction approaching the casing. The stopper device has a rotating plate equipped with a section that enters and exits from between the anode support body and the casing due to rotation, a motor for driving the same, and a plurality of stop members provided in a peripheral section of the rotating plate and having mutually different heights.

Abstract: Provided are an X-ray generator capable of easily measuring a beam size of an electron beam on an electron target, and an adjustment method therefor. The X-ray generator includes an electron target including a first metal, a second metal different from the first metal, and a third metal different from the second metal, which are sequentially arranged side by side along a first direction in a continuous manner.
