| A comprehensive theoretical investigation on the specific electron transport coefficient in the He-Ne gas mixtures state in plasma has been carried out. The performed calculations enable us to measure the influence of the concentration of He:Ne gas mixture on plasma electronic coefficients. Our approach is based on the variation in the resistance of plasma field placed in a varying reduced electric field and thermodynamic equilibrium. The effects of reduced electric field and mixture concentrations on the electron mobility, diffusion coefficients, and total collision frequency have been calculated by solving the Boltzmann equation using the two-term approximation. The Monte Carlo simulation was used to solve the Boltzmann equation. The polynomial and logistic functions were adopted through the simulation process, and the appropriate equations have been provided, indicating the variation of plasma electronic coefficients to the variation of gas mixture concentration and reduced electric field. The applied reduced electric field has been chosen to be in the limited range of 0-100 Td, and is considered for several concentrations in the limited range of 0.1-0.7 mol. The study shows that the obtained results are in good agreement with the results obtained using the Monte Carlo method. |
