Abstract:

This effort was a continuation of both a theoretical and experimental program leading to the development of high voltage, high power switching devices which utilize a liquid metal cathode. Refinements in the plasma injected mercury tubes have culminated in a switch capable of passing 200KA and 1.2 gigawatts with current risetimes of less than 20 nanoseconds. Improvements in anode cooling have led to a theoretical prediction of 800KW average power operation. Problems and solutions in the handling and operation of the liquid sodium devices are presented. Test data is analyzed and compared with the mercury work. Author
