Automated test system for NIF flashlamps

Summary form only given, as follows. This paper describes the flashlamp test system overall design and operation. The flashlamp tester is used to evaluate the primary laser flashlamps used on the National Ignition Facility (NIF) at the Lawrence Livermore National Laboratory (LLNL) in Livermore, California. The flashlamp tester delivers repetitive high voltage pulses to a series pair of flashlamps at levels closely simulating those encountered in normal operation. Each lamp pair is subjected to a pre-ionization and main pulse shot sequence with two-minute intervals between shots. This capability allows the manufacturer to test and evaluate the flashlamps for mortality and longevity before delivery to the facility. All operations are under computer control with fully automated test and data acquisition capabilities requiring minimal operator input. The system is designed to operate continuously.
