Emission properties, microstructure and surface composition of scandate impregnated cathodes with tungsten and a tungsten-rhenium matrix

Abstract

The investigation of emissive ability, lifetime, structure and component surface composition of scandate cathodes with a matrix of tungsten and of tungsten-rhenium matrix impregnated with barium-calcium aluminate (4:1:1 or 6:1:2 moles) with 0.5-5 weight nonuniform emission can be explained by formation of crystals up to 100 nm in size consisting mainly of… (More)
