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.
Claims8
An X-ray generation device comprising:
- an X-ray tube;
- and
- an electron beam adjustment part,
- wherein the X-ray tube includes a housing, an electron gun that emits an electron beam inside the housing, a target that generates an X-ray upon an incidence of the electron beam inside the housing, and a window member that seals an opening of the housing and that transmits the X-ray,
- a window member defect exists in the window member, and
- the electron beam adjustment part adjusts the electron beam such that the window member defect is not included in a projection region of the electron beam on the window member.
