Analytical Solution of the Equations for a Coaxial Plasma Gun Operating in the Snowplow Mode. 1. Weak Coupling Limit

摘要

The analysis solution of the system of coupled ordinary differential equations which describes the time evolution of an ideal coaxial plasma gun operating in the snowplow mode is obtained in the weak coupling limit, i.e., when the gun is fully influenced by the driving (RLC) circuit but the circuit is negligibly influenced by the gun. Criteria are derived for the validity of this limit, and numerical examples are presented.
