Effect of inductance on the small-signal gain of a transverse-excitation atmospheric-pressure discharge in carbon dioxide

An external inductance was placed in the circuit of a resistive transverse-excitation atmospheric discharge to observe its effect on the small-signal gain of a CO2-He-N2gas mix. The results of the measurements indicate that by lowering the inductance of the circuit, less helium is required in the gas in order to obtain a uniform discharge; consequently, more CO2and N2may be used with higher gains resulting.
