    Abstract: A vacuum-tight body composed of at least two carbon members which are joined to one another with a layer of a gas-impermeable solder material selected from the group consisting of Cu, Ag, Au, and alloys thereof in direct contact with a rhenium layer on adjoining carbon surfaces. The body may form a collector which forms part of a vessel wall in a high capacity electric discharge vessel.

    Abstract: A cathode structure, particularly a MK cathode, employs a wick mounted in a coupling member adjacent a supply of emission substance, preferably barium. The wick may be formed of a number of very thin tungsten wires which are snaked or braided together and covered with a cylindrical coating of, for example, molybdenum. The wick and the emission supply substance are mounted in a housing adjacent a heater element for indirect heating. A matrix of cathodes is provided by fixing coupling members having wicks mounted therein in a spaced apart manner in an insulating plate. In such a matrix heater are disposed and secured in place between adjacent cathodes. The heaters may be jointly operated, but advantageously with different applied voltages.

    Abstract: A dispenser MK-type cathode structure adapted for storage and/or handling with subsequent activation and a method of producing the same whereby a supply source substance for an emission-promoting substance (i.e., barium oxide) is positioned in an open end storage chamber of a pluglike insert member (composed of tantalum), and the supply source substance is surrounded with an inert atmosphere at ambient pressure and sealed by a gas impermeable foil member (composed of tantalum). A plurality of such insert members are mechanically mated with a ring-shaped cathode body member (composed of molybdenum) so that the foil member separates the supply source substance from the cathode body member. A suitably porous tungsten disk is mounted on the cathode member body in communication with the foil member so that by evacuating the area around the cathode structure the foil ruptures and the emission-promoting substance (released by heat from the supply source substance) is free to come into contact with the adjacent underside portions of the porous disk. Each of the insert members is provided with shaped contact surfaces to positively seal the foil members between the insert member and the body member.
