Abstract: An X-ray generator comprising a target for receiving electrons and generating X-rays, a separator for dividing an internal space of the target into a coolant inflow path and a coolant outflow path, a motor for rotating the target, and a coolant inflow path and a coolant outflow path for supplying a coolant to the coolant inflow path and recovering the coolant through the coolant outflow path, wherein the separator rotates in the same rotation direction as the target when the target rotates. In the X-ray generator in which a coolant inflow path and a coolant outflow path are provided by a separator inside a rotating target, reduced torque load and reduced vibration can be realized.

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.
