    Abstract: Provided is an X-ray generator including an electron passage in an electron-passage forming member; and a target on an insulative substrate. The transmission X-ray generator irradiates the target with electrons that have passed through the electron passage to generate X-rays. The target is provided at a central region of the substrate; the electron passage accommodates a secondary-X-ray generating section that generates X-rays by irradiation with electrons reflected from the target; the secondary-X-ray generating section and the target are disposed so that both of X-rays generated by direct irradiation of the target with the electrons and X-rays generated by irradiation of the secondary-X-ray generating section with the electrons reflected from the target are radiated to the outside; and at least part of the peripheral region of the substrate has higher transmittance for the X-rays generated at the secondary-X-ray generating section than the central region of the substrate.

    Abstract: The present invention relates to a radiation generating apparatus which includes an envelope provided with a first window through which radiation is transmitted, a radiation tube housed in the envelope and provided with a second window through which the radiation is transmitted, the second window being located at a position opposite the first window, and an insulating fluid adapted to fill the space between the inner wall of the envelope and the radiation tube. Plural plates are arranged side by side between the first window including its periphery and the second window including its periphery, and overlapping one another with gaps between them. The gaps are formed among the plates, and thereby the withstanding voltage between the first window and second window is made larger.

    Abstract: Provided is an X-ray generator comprising an X-ray tube including a cylindrical body; an electron source in the body; a target at an end of the X-ray tube facing the electron source, the target generating X-rays by irradiation with electrons; a container in which the X-ray tube is arranged; insulating liquid filled between the X-ray tube and the container; and a holding member holding the body of the X-ray tube in the container, with a channel for the insulating liquid around the X-ray tube. The distance between the holding member and the end face at the end of the body in the direction in which the electron source and the target face is twice or more as large as the minimum width of the channel that is in contact with the outer surface of the X-ray tube at the end face side with respect to the holding member. This allows heat in the target to be quickly radiated, thus allowing X-rays to be generated stably for a long time.
