ABSTRACT:
Composite electrodes for a crossed-field switch device is formed by positioning a refractory metal structure substantially at the location of its first electrode, sputtering metal from the refractory metal structure onto the second electrode so that the second electrode is coated with refractory material, then removing the refractory metal structure and replacing the first electrode, followed by back sputtering onto the first electrode.
