Resistively Decoupled Explosive-Emission Cathodes for High-Current Plasma-Filled Diodes

详细

The design and characteristics of resistively decoupled multi-emitter explosive-emission cathodes intended for high-current plasma-filled diodes are presented. The integral glow of the emission-center plasma, the energy-density distribution over the cross section of a nonrelativistic high-current electron beam, which is formed in the plasma-filled diode, and the operation lifetime of the cathode were studied. The best results were obtained for a cathode based on TVO-1 resistors, whose wire outputs serve as emitters.
