Experimental determination of paschal curve and first townsend coefficient of nitrogen plasma discharge

Abstract EN

In the present work, an experimental study is performed to determine the first Townsend coefficient and Paschen curve for N2 gas using a parallel plate geometrical configuration.

Paschen curve coefficients are derived by exponential fitting of first Townsend coefficients data of plasma discharge.

The experimental data are acquired at different working pressure and various electrode gap separations.

Furthermore, the amplification process of the gas gain in a uniform electric field is realized.
