Abstract

These researches of forming of composition and structure of the adsorbed matters layer and emission сharacteristics of traditional and impregnated barium scandate cathodes are generalized depending on the parameters of structural elements (metallic carcass, emission-active matter and film) after the thermal activating and tests on life.
