Pulse shaping techniques for mega ampere current on Atlas pulsed power machine

Atlas is one of the world's largest pulsed power systems designed by Los Alamos National Laboratory (LANL) to perform high energy density experiments in support of weapon-physics and basic research programs. The current pulse generated by Atlas is a damped sinusoid that rises to nearly 30 MA in 6 microseconds as it flows through the load (target). The models developed here evaluate the Atlas reconfiguration in order to obtain a compressed pulse with a much faster rise-time for magnetic compression experiment, and another expanded current pulse with a much slower fall-time for driving very heavy liners. Comparative studies of various types of switches that can be implemented on Atlas have been examined. The simplified models representing the Atlas reconfiguration are simulated using the PSpice circuit simulation tool to obtain accurate wave shapes based on time varying parameters.
