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.
