A dispenser cathode which consists of a porous body of tungsten impregnated with barium scandate has been developed. It has good properties: high emission current density, low evaporation rate, good reactivation ability after poisoning and long life. This kind of cathode is suitable for use as an electron emitter for certain high power microwave tubes and the like.
