Summary form only given. The designs of busbars and switches for efficiently transferring energy to the IGNITEX single-turn tokamak and to the IGNITEX Technology Demonstrator (ITD) are presented. Unlike the full-scale IGNITEX, the ITD experiment requires fast closing switches. A coaxial switch is integrated into a coaxial/flat-plate transition in each busbar. The switch operates when an explosive cord propels an expendable copper throw ring. The throw ring lodges into an annular gap between two copper catch rings. transferring current to the TF (toroidal field) coil. The busbar conceptual design of the full-scale IGNITEX experiment is discussed. A goal of the design is to minimize the system's energy requirements. Resistive losses are reduced by locating the generators in close proximity to the experiment and by precooling the conductors to liquid-nitrogen temperature. The outer radius of the containment's primary shielding indicates a length of 6 m for each TF-coil busbar. The inductance of multimegampere busbars is reduced by laminating multiple conductors, alternating polarities as they are stacked. Laminating reduces the bus inductance proportionate to the number of laminations |
