    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 photomultiplier tube comprises an evacuated envelope having a photoemissive cathode therein. A cage assembly including an anode and a plurality of closely spaced dynodes are within the envelope. The anode has at least one support rod. Each of the dynodes has a pair of dynode tabs formed in the ends thereof. A pair of dynode support spacers having a plurality of stress isolation apertures and electrode support apertures formed therethrough are provided for supporting the dynodes and the anode. The dynode tabs and the anode support rod extend through the electrode support apertures. A plurality of deformable stress isolation eyelets comprising a tubular shank with a flare formed in one end of the shank are disposed within a different one of the stress isolation apertures. The flare diameter is greater than the diameter of the stress isolation apertures thereby retaining the eyelets within the apertures. A second end of the tubular shank, opposite the flared end, extends outwardly from the dynode support spacers. The outwardly extending end portion is crimped to lock the eyelets within the stress isolation apertures. Nickel leads are provided for flexibly interconnecting the crimped end portion of a different one of each of the eyelets to one end of each of the dynodes and to one end of the anode support rod. A stem closes one end of the envelope. A plurality of relatively stiff cage assembly support leads extend through the stem and are welded to the crimped end portion of the eyelets thereby firmly securing the cage assembly to the support leads and indirectly connecting the support leads to the dynodes and the anode.

    Abstract: A low volume, lightweight, high voltage electron gun having an overall size and weight of approximately 50% the size and weight of a conventional electron gun of the same output. This is accomplished by interposing between the cathode and the walls of the housing of the electron gun a thin piece of dielectric material of preselected breakdown strength. The dielectric material is in direct contact with both the cathode and the housing of the electron gun, with the voltage stress between the walls of the housing and the cathode being such that it does not exceed the breakdown strength of the dielectric material.

    Abstract: An electron beam device having a tubular body of elongate shape with an electron exit window extending in the longitudinal direction of the tubular body. The tubular body is at least partly forming a vacuum chamber, the vacuum chamber comprising therein a cathode comprising a cathode housing having an elongate shape, and at least one electron generating filament and a control grid both extending along the elongate shape of the cathode housing. The control grid and the cathode housing are attached to each other by attachment mechanisms. Free longitudinal end portions of either the control grid or the cathode housing are bent in a direction towards each other to form bulge-like shapes for the formation of electron beam shaping electrodes. The invention is further comprising a method of manufacturing the electron beam device.
