FIXED ANODE X-RAY TUBE, X-RAY INSPECTION DEVICE USING THE SAME, AND X-RAY IRRADIATION DEVICE

摘要

A fixed anode X-ray tube includes: a cathode generating an electron beam; an anode having a target against which the electron beam from the cathode collides to form a focal point of the X-ray source and generate an X-ray from the focal point; and an outer circumference device supporting the cathode and the anode in such a way that the cathode and the anode are arranged to oppose to each other, containing the cathode and the anode in vacuum tight state, and having an X-ray extraction unit for extracting the X-ray from the target. The position of at least the anode target is arranged with an offset toward the X-ray extraction unit from the center axis in the longitudinal direction of the outer circumference device.
