Abstract:
1. An X-ray generating apparatus, comprising: a tube body, which is constructed to be vacuum in an inside thereof; an electron source, which is provided within said tube body to generate an electron beam therefrom; a target, which is provided within said tube body and irradiated with the electron beam emitting from said electron source, thereby to generate an X-ray therefrom; and an X-ray window, which is provided for taking out the X-ray generated into an outside of said tube body, wherein on a surface of a member building up said target are formed plural numbers of grooves, each having fine width, repetitively, thereby irradiating the electron beam from said electron source, inclining by a predetermined angle, from a direction perpendicular to an elongating direction of said grooves, so that they bridge over said plural numbers of grooves, and also a multi-line X-ray generating from the plural numbers of multi-line targets, which are formed between said grooves, emits at a predetermined extraction angle, passing through said X-ray window, said predetermined extraction angle is such an angle that is covers over portions, upon which said electron beams irradiate directly, among a surface forming said grooves thereon.
