摘要： An emitter-dispenser housing (48) for a controlled porosity dispenser cathode manufactured of a single material as a unitary piece by a chemical vapor deposition process in which a configured mandrel (20) is coated with a layer of material (36 and 40) such as tungsten, for example, so that when the mandrel (20) is removed from the coating of material (36), a hollow housing (48) is formed having a side wall (36 and 40) and an end wall (42) which define a reservoir (44). In addition, intersecting strips (28 and 30) of this same material as the coating, which had been placed in the mandrel (20), extend transversely across the reservoir (44) with the edges thereof bonded by atomic-crystalline growth to the coating (36 and 40) during the chemical vapor deposition to form a unitary piece. Thereafter, an array of apertures (46) is formed in the end wall (42) of the housing by laser drilling to create an emitter-dispenser (42).
