Abstract
An X-ray generation device includes an X-ray tube, and an electron beam adjustment part. The X-ray tube includes a housing, an electron gun, a target, and a window member. When a first defect exists in the target, the electron beam adjustment part adjusts an electron beam such that the first defect is not included in an irradiation region of the electron beam on the target, and when a second defect exists in the window member, the electron beam adjustment part adjusts the electron beam such that the second defect is not included in a projection region of the electron beam on the window member.
