Abstract

Newly constructed, high power ignitions have been tested using an electrolytic bank. The goal of this project, which was named Hercules, was to lifetime test high power switches for Lawrence Livermore's NOVA laser upgrade program. The tubes that have been tested were the NL-9000A from Richardson Electronics, and the BK-1002 from English Electric Valve (EEV). Both tubes have stainless steel, cup style anodes. Both tubes were connected in series for the tests. Required test parameters were Ipeak = 300 kA, Qtransfer = 200 C. During the tests, the BK-1002 tube failed due to ignitor shorting. The average forward voltage drop across the EEV tube was higher than the drop across the NL-9000A. After the tube failure, the BK-1002 was replaced by a NL-1057 to continue testing of the NL-9000A.
