    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).

    Abstract: An apparatus for assembling and inspecting an electron gun of a cathode ray tube includes a mandrel 5 and a measuring nozzle 2. The mandrel 5 has an outer diameter larger than the electron-beam-transmission hole of the Gm electrode 30. The mandrel 5 abuts against the Gm electrode 30 from G3 electrode 40 side, to seal the electron-beam-transmission hole of the Gm electrode 30. The measuring nozzle 2 has a tip that can be inserted through the electron-beam-transmission holes of the G1 and G2 electrodes from the G1 electrode side, and blows air toward the mandrel 5. A clearance between the G2 and Gm electrodes are measured according to the change in pressure of the blown air. It is possible to measure the clearance between the electrodes required for assembling the electron gun having the Gm electrode with a small electron-beam-transmission hole.

    Abstract: An electric high-voltage apparatus such as an electron accelerator or the like includes a tank having a wall and a tank access located in the wall for making the interior of the tank accessible. An electrical discharge vessel is disposed in the tank and contains replaceable parts. The vessel has a wall and is insulatingly spaced from the tank wall. A vessel access is located in the vessel wall for making the replaceable parts accessible. A tube-like air lock device having a longitudinal axis is movable in the tank transversely to this axis from a given rest position to an operative position located between the tank access and said vessel access. The device includes expansion structure for defining a gas-tight passage between the vessel access and the tank access when the device is in the operative position thereof.
