Abstract : The basic objective of the program was to determine the feasibility of using a novel type of spark-gap switch called a cross-field closing switch for applications at the 60-kV, 20-kA, 20-microsec level. This entailed single-shot testing at these levels to determine the following critical items: (1) anode fall time, (2) ignition jitter, (3) voltage recovery rate, (4) gas cleanup rate, (5) arc uniformity, and (6) triggering and control levels. A second objective of this program was to design a cross-field closing switch to operate at the above levels, but at a repetition rate of 250 Hz, that gave an average switch current of 100 A. The experimental program proved the feasibility of the tube on a single-shot basis. (Modified author abstract)
