摘要： 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.

摘要： In an X-ray tube having an X-ray shielding member allowing an electron ray to pass through an electron passing hole toward a target, separately from the cathode-side opening of the electron passing hole, a gas exhaust path allowing communication between the inside and outside of the electron passing hole is provided so that gas molecules generated in the electron passing hole can be easily diffused out of the electron passing hole. The degradation of the cathode caused by accelerated collisions with the cathode, of cations generated by collisions of electrons with gas molecules generated in the electron passing hole by a desorption phenomenon due to electron ray irradiation to the target, is reduced.

摘要： An X-ray tube comprises: an envelope which has a cathode at one end and an anode at another end of a barrel of a tubular insulating tube and which has a sealed interior; an electron gun which is arranged inside the envelope and has a shape that protrudes from the cathode; and a target which is electrically connected to the anode and generates X-rays when being irradiated with electrons emitted from the electron gun. With reference to an end position that is a projection of a position of an end on the anode side of the electron gun onto an inner wall of the insulating tube, a mean wall thickness of the barrel is greater on the cathode side than on the anode side.
