- This paper calculates the plasma parameters in optically thick condition by utilizing two spectral line in same ionization degree. Sumation and ratio of spectral lines by presenting a new model estimate acqurately the evolution of plasma dynamic. In this analysis, it is assumed the plasma is located in LTE condition. By using theoretical calculation and experimental set-up, plasma parameters such as temperature and species densities can be obtained. Input parametrs extracted from experiment in this semi empirical model are lines intensities, plasma length and electron density.
