    摘要: A directly heated cathode structure includes a porous pellet impregnated with a cathode material, filaments connected to the porous pellet, a support supporting the filament, and an insulation block supporting the support, wherein the filaments are supported on the porous pellet by at least one auxiliary member. The supporting structure is very strong and the quality and productivity can be greatly improved by improvement of the filament welding process using the auxiliary members.

    摘要: A directly heated cathode structure includes a porous pellet impregnated with a cathode material, a first metal member fixed to a surface of the porous pellet, a second metal member welded to the first metal member, and a filament interposed between the first and second metal members. A method for manufacturing a directly heated cathode structure includes manufacturing a porous pellet having a multiplicity of cavities, welding a first metal member to a surface of the porous pellet with a brazing layer, impregnating the cavities of the pellet with an electron radiating material, and welding a second metal member to the first metal member with a filament disposed between the first and second metal members. The useful life of the cathode structure is prolonged since thermions are not emitted through the surface of the pellet covered by the metal member.
