Abstract
High reliability, long lifetime and low temperature, high emission current density oxide cathodes are presented in this paper.
The characteristics of these cathodes, such as dc and pulse emission, evaporation, resistance to poisoning and lifetime, are
discussed. They have been widely applied to TWTs and klystrons with high power, long pulse and high duty ratio. The results
showed that high emission current density and long lifetime can be realized.
