Switch evaluation test system for the National Ignition Facility
Flashlamp pumped lasers use pulse power switches to commute energy stored in capacitor banks to the flashlamps. To lower the total cost of these switches, Sandia National Laboratories has a research program to evaluate large closing switches. The National Ignition Facility (NIF) is one of the applications of the program designed by Lawrence Livermore National Laboratory, Los Alamos National Laboratory, and Sandia National Laboratories. The target value of the energy switched by single devices is 1.6 MJ, from a 6 mF, 24 kV capacitor bank. The peak current is 500 ka. The lifetime of the NIF facility is 24 thousand shots. The goal of the experiment in Sandia is to test switches with the full NIF wave shape, and the correct voltage.
