Abstract
The results of studying the emissive ability, structure, and elemental composition of the surface of an impregnated cathode with a fine-grained tungsten matrix with addition of polyhedral multilayer carbon nanostructures of the fulleroid type (0.2−0.7 wt %), impregnated with barium-calcium aluminate with addition of sulfoadduct of carbon nanoclusters (0.1−0.2 wt %), are presented. The tests in diode prototypes showed that these cathodes provide a current density of 20 A/cm2.
