For electricity production in a 1000 MW(e) Z-Pinch Inertial Fusion Energy (IFE) power plant, a wire array must be produced and shot every second. The slow and painstaking manual assembly and insertion process developed for the present Z-Pinch experimental machines will have to be replaced with mass production and rapid auto matic handling. This could be facilitated by making one-piece, or unitized, wire arrays (UWA). This paper reviews potential UWA manufacturing processes; describes the results of etching, milling, laser-cutting, and lithography tests applied to an UWA design that could be shot on the Z-R machine for validation; assesses the feasibility of these processes for mass production; and proposes an alternate UWA design concept for easier manufacturing.
