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

Abstract

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)(Ω 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.

Analytical Solving a Nonlinear Model of the Glow Discharge

“…Electric discharge in gases [1][2][3] has played a significant role in the emergence and development of modern physics, and in addition to its many applications in science and technology [4][5][6][7], it remains a field for experimental and theoretical research [8][9][10]. The glow discharge is very important in a wide range from glow discharge lamps [11] to energy injection in continuous and pulsating gas lasers such as carbon dioxide [12] and excimer [13] laser.…”

An innovative method for plasma characterization of the spark pre-ionization pulsed TEA-CO2 laser

“…Techniques such as interferometers and/or Thompson scattering are classic methods [8]. However, other innovative simple works have been published recently using regular methods for the measuring of the electron density for transient plasmas [9][10][11]. In this report, our main goal is to identify a semi-analytical method for approximating the electron density in the plasma discharge tube.…”
