Title (EN) MULTIPLE GRID FABRICATION METHOD
(FR) METHODE DE FABRICATION DE GRILLES MULTIPLES
Abstract: front page image
(EN)Method of fabricating an improved multiple grid electrode having a plurality of discs by simultaneously forming a dimpled segment in a sandwich structure consisting of metallic discs (42, 43, 44) separated by spacer material (46, 47). The dimpled sandwich structure is then machined, forming a series of vanes on the dimpled portion by an appropriate method, such as electrical discharge. After machining, the spacer material (46, 47) is etched away, leaving only the vaned discs, (42, 43, 44) forming grid electrodes.
(FR)Une methode de fabrication d"une electrode a grilles multiples amelioree ayant une pluralite de disques consiste a former simultanement un segment a alveoles dans une structure en sandwich consistant en disques metalliques (42, 43, 44) separes par un materiau d"espacement (46, 47). La structure en sandwich a alveoles est ensuite usinee, formant une serie d"ailettes sur la portion en alveoles par une methode appropriee, telle que la decharge electrique. Apres usinage, le materiau d"espacement (46, 47) est enleve par attaque chimique, laissant seulement les disques en ailettes (42, 43, 44) formant des electrodes a grilles.
