  • Controlled-porosity dispenser cathode
    Patent number: 4101800
    Abstract: An emissive member for a controlled-porosity, dispenser-type cathode comping a three-component sandwich consisting of: (1) a supporting disc; (2) a layer of nonsintered alkaline earth material on said disc; and (3) a thin perforated foil on said layer. The foil is made of refractory metal and has a uniform pattern of tiny holes through which the active material of the reservoir migrates to coat the surface of the foil, the foil thus serving as the electron-emitting surface of the cathode.
