ABSTRACT:
The present invention is directed to an apparatus for producing a vacuum arc in a plasma centrifuge. The apparatus comprises a cathode of a material from which the vacuum arc is formed and a trigger electrode. A trigger circuit is coupled to the trigger electrode for storing energy and then applying a break down voltage between the cathode and the trigger electrode where the cathode breaks down and initiates the vacuum arc. A pulse forming circuit is electrically coupled to the cathode for supplying a constant current pulse to the cathode to enhance the formation of a completely ionized plasma. The resistance of the pulse forming network is lower than the impedance of the vacuum arc. The present invention also in directed to an anode grid holder for use in the plasma centrifuge.
