    Abstract: An X-ray generating apparatus includes an X-ray generating tube including an electron gun and a target configured to generate X-rays upon receiving an electron beam emitted from the electron gun, a deflector configured to deflect the electron beam, a driving circuit configured to apply an accelerating voltage between a cathode of the electron gun and the target, and an adjuster configured to adjust deflection of the electron beam by the deflector in accordance with the accelerating voltage or an amount of change in the accelerating voltage so as to reduce a change in incident position of the electron beam onto the target due to a change in the accelerating voltage.

    Abstract: An X-ray generation device includes a cathode including an electron source generating an electron beam, an anode including a target to transmit an X-ray generated by collision of the electron beam, and a convergence electrode converging the electron beam toward the target. The target has a first region having a locally small thickness and a second region having a larger thickness than the first region. The X-ray generation device further includes a deflection unit to switch an incident position of the electron beam between the first region and the second region. The deflection unit has an adjustment mode to adjust an X-ray focal spot diameter and an X-ray generation mode to generate an X-ray, the electron beam is caused to enter the first region in the adjustment mode, and the electron beam is caused to enter the second region in the X-ray generation mode.
