Abstract
An X-ray generation device includes an electron gun emitting an electron beam, an X-ray generation target including a plurality of target parts generating X-rays in response to incidence of the electron beam from the electron gun, and an irradiation area switching unit switching an area of the X-ray generation target irradiated with the electron beam between a first irradiation area and a second irradiation area. The number of target parts included in the first irradiation area is larger than the number of target parts included in the second irradiation area. An area of the target parts included in the first irradiation area is larger than an area of the target parts included in the second irradiation area.

An X-ray generation device comprising:
- an electron gun emitting an electron beam;
- an X-ray generation target including a plurality of target parts generating X-rays in response to incidence of the electron beam from the electron gun;
- and
- an irradiation area switching unit switching an area of the X-ray generation target irradiated with the electron beam between a first irradiation area and a second irradiation area,
- wherein the number of target parts included in the first irradiation area is larger than the number of target parts included in the second irradiation area, and
- wherein an area of the target parts included in the first irradiation area is larger than an area of the target parts included in the second irradiation area when seen in an incidence direction of the electron beam.
