Theoretical Modeling of the Plasma Erosion Opening Switch for Inductive Storage Applications.

Abstract

A theoretical model for the plasma erosion opening switch (PEOS) is presented which predicts its voltage, current and impedance history as a function of the input waveforms, geometry and switch parameters. Scaling laws for the switch operation are developed from this model. System requirements for pulse compression and power multiplication using inductive storage are derived from a simple lumped circuit analysis and a transmission line analysis. These requirements are shown to be satisfied using the PEOS as a fast opening, vacuum switch in a configuration relevant for existing high power accelerators. The switch model is incorporated into a transmission line code for comparison with recent inductive storage experiments. Code results agree well with the data and show conduction times of approximately 60 ns, switching times of approximately 10 ns with peak currents of approximately 600 kA. (Author)
