    Abstract: 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).

    Abstract: Boîtier émetteur-distributeur (48) pour une cathode distributrice de porosité contrôlée fabriquée dans un matériau simple en tant que pièce unitaire selon un procédé de déposition de la phase de vapeur chimique au cours duquel un mandrin configuré (20) est enduit d'une couche de matériau (36 et 40) comme le tungstène, par exemple, de façon que, lorsque le mandrin (20) est retiré du revêtement de matériau (36), soit formé un boîtier creux (48) possédant une paroi latérale (36 et 40) et une paroi terminale (42) délimitant un réservoir (44). En outre, des bandes s'entrecoupant (28 et 30) de même matériau que le revêtement, qui a été placé dans le mandrin (20), s'étendent transversalement à travers le réservoir (44) dont les bords sont liés par croissance atomique et cristalline au revêtement (36 et 40) lors de la déposition de la phase de vapeur chimique pour former une pièce unitaire. Ensuite est formée une rangée d'ouvertures (46) dans la paroi terminale (42) du boîtier par perforations au laser afin de créer un émetteur-distributeur (42).
