Recombination and Ionization in a Nitrogen Plasma.

Abstract

A collisional-radiative model for nitrogen plasma (N,N+, and N++) has been developed. The results for an optically thin, and optically thick in uv lines, are presented. The approach taken in the model is to solve a time dependent set of rate equations for a large number of excited states of N and N+ for a wide range of Tellurium and Neon. The excited states of interest emit radiation in the ultraviolet, visible and infrared which could be used for air plasma channel diagnostics. The model delineates the regimes in Te and Ne where the excited states are in Local Thermodynamic Equilibrium and when they deviate from LTE, and is developed as a building block for an extensive radiative transfer model for air.
