Abstract: An electron gun also has a cathode for emitting electrons, a heater cap which contains a heater for applying the cathode with thermal energy for emitting electrons, a retainer for securing the cathode on the heater cap by clamping the peripheral edge of the cathode onto the heater cap, and a cylindrical Wehnelt supporter. The cylindrical Wehnelt supporter has a Wehnelt electrode for focusing an electron beam that is formed in such a shape that an average angle of the surface thereof with respect to an outermost shell of the electron beam matches a Pierce angle, and three or more heater cap supporters for securely supporting the heater cap at a position at which an electron emitting surface of the cathode and an opening formed through the wehnelt electrode satisfy a predetermined perveance.

Abstract: A nondestructive inspection apparatus with integrated power supply comprises a molded power supply section (14) having a resin-molded high voltage (e.g. 160 kV) generating section (15) secured to the base of a tubular section (2). The durability and handlability are improved by omitting a high voltage cable. Since the high voltage generating section (15) is confined in a molding resin, the degree of freedom in the arrangement of the high voltage generating section (15) within the mold is enhanced significantly. Furthermore, an X-ray generating unit (1) can be installed stably in the nondestructive inspection apparatus (70) by disposing the heavy molded power supply section (14) under a target (10).
