Abstract
Several different types of cathode are known as dispenser cathodes. They are of interest to the microwave valve designer because they offer various advantages over the oxide cathode, chiefly that of-higher current density. The processes that activate the surfaces of these cathodes and the mechanism of electron emission are described in this paper.
