Fast Ionization Waves in Extended Capillaries Initiated by High-Voltage Pulses With Varying Rise Rates: A Numerical Investigation

This article presents the results of numerical investigations of initial stages of a fast capillary discharge-initiation and propagation of a fast ionization wave and consequent formation of a conducting plasma channel. Simulations were performed for the case of a 10 cm-long narrow capillary filled with argon at 270 Pa. The wave was created by voltage pulses of negative polarity with an amplitude ...
