Infant-mortality testing of high-energy-density capacitors used on Nova
Abstract
Nova is a solid-state large laser for inertial-confinement fusion research. Its flashlamps are driven by a 60-MJ capacitor bank. Part of this bank is being built with high energy density capacitors, 52-(SIGMA)F, 22 kV, 12.5 kJ. A total of 2645 of these capacitors were purchased from two manufacturers. Each capacitor was infant-mortality tested. The first test consisted of a high-potential test, bushing-to-case, since these capacitors have dual bushings. Then the capacitors were discharged 500 times with circuit conditions approximating the capacitors normal flashlamp load. Failure of either of these tests or if the capacitor was leaking was cause for rejection.
