A 3-MJ capacitor bank for the SNL electroexplosive facility
Abstract
A 3-MJ capacitor bank was added to the Electroexplosive Facility for injecting the initial magnetic energy into large explosive generators. It consists of two 800-(SIGMA)F modules that are first charged to +60 kV and -60 kV, respectively, and then discharged in series by explosive detonator switches to provide 400 (SIGMA)F at 120 kV. The bank was designed to deliver priming currents up to 2 MA and to have an energy transfer efficiency of 0.7 to 0.84 for generator inductance of approximately 10 (SIGMA)H. Type 17/14 coaxial cable will be used to interconnect the capacitor modules, detonator switches, and load. All generators primed by this bank will be crowbarred at peak current to limit capacitor voltage reversal and extend the life of the capacitors. The major components of the system are described.
