Abstract

See full text

Provided is a high-output X-ray generation tube in which thermal damage to a target is reduced. The X-ray generation tube includes a target, an electron source, and a grid electrode having multiple electron passage apertures disposed between the target and the electron source. A source-side electron beam on the electron source side with respect to the grid electrode has a current density distribution, and the grid electrode has an aperture ratio distribution so that a region of the source-side electron beam in which a current density is largest is aligned with a region of the grid electrode in which an aperture ratio is smallest.
