Abstract: 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.
