An Innovative Simple Method for Study of the Characteristics of the Trigatron Plasma Switch

A simple Semi-Analytical method used to fit the experimentally recorded current of the closed switch discharge circuit into the free running under damped LC oscillator model and the arc plasma conductivity, electron density of the plasma and efficiency of the spark gap switch energy transfer have been driven from the model by some simple calculations. The charging voltage, switch pressure and the spark-gap has been changed between 6 to 15 kV, 1 to 1.5 bar and 1.4 or 2.8 mm, respectively. The obtained values for plasma conductivity and electron density of plasma are (5-25)(Omega mm)(-1), (0.5-3.5).10(24)m(-3), respectively. The efficiency of the switch is plotted Vs. Pd and E/P which in both cases the peak value has been about 80 present. (C) 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
