Abstract: An X-ray generator includes a booster circuit formed by sequentially connecting a plurality of boosting steps extending from a low-voltage terminal to a high-voltage terminal of its own.The booster circuit is arranged in a lateral region of the X-ray tube so as to make the low-voltage terminal of its own correspond to the anode of the X-ray tube and the high-voltage terminal of its own correspond to the cathode of the X-ray tube. A lead wire extending from the cathode to the outside of the X-ray tube is connected to the high-voltage terminal of the booster circuit. A molded member containing insulating resin is formed to shield at least a cathode side end part of the X-ray tube, the lead wire outwardly extending from the cathode side end part and a high-voltage terminal side end part of the booster circuit.

Abstract: An industrial X-ray tube formed by accommodating a cathode and anode in a container having an evacuated interior, in which electrons emitted from the cathode are caused to strike the anode and X-rays are emitted from the anode. The cathode is formed from graphite. The graphite is a layered crystal obtained by layering a plurality of carbon hexagonal planes. The graphite is cut based on crystal axes of the carbon hexagonal planes. The resulting cut surface is caused to function as an electron-emitting surface. For example, directions of an a- and b-crystal axis may be set so as to be arbitrary between each of the layers of the carbon hexagonal planes, the graphite may be cut along a surface parallel to the c-axis, and the resulting cut surface may be caused to function as an electron-emitting surface. The graphite may also be cut along a surface orthogonal to the c-axis.
