Abstract: A method of manufacturing a storage cathode comprising the steps of forming a first layer of electron emissive material in a holder, said layer comprising a loose mixture of coarse and fine granulated particles of electron emissive material, depositing on said first layer a second layer consisting essentially of loose tungsten particles and compressing said layer in the holder at the sintering temperature below the fusion temperature of the electron emissive material to sinter the second layer and form a unitary body of the layer in the holder.
