Abstract:
1. An industrial X-ray generator comprising: an X-ray tube that stores a cathode for emitting electrons and an anode for attracting electrons in a tubular body thereof; an X-ray shielding member that is made of a substance mainly containing an element of an atomic number not smaller than 55 and hardly allowing X-rays to pass through the substance and covers the X-ray tube; a booster circuit that generates a high voltage to be applied to the cathode; the anode being grounded, the booster circuit being 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 being 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, an electroconductive member extending from the cathode to the outside of the X-ray tube and connected to the high-voltage terminal of the booster circuit; and a molded member containing insulating resin and formed to shield at least a cathode side end part of the X-ray tube, the electroconductive member extending from the cathode side end part and at least a high-voltage terminal side end part of the booster circuit.
