jasim mohammed salih ali

Abstract


Abstract:
In this work, we were calculate the electron diffusion coefficients, such as, the drift velocity, characteristic energy, and collision frequencies using the cross sections of the momentum transfer and inelastic for electrons in CO2 from figure(1) after solving the Boltzmann transport equation numerically using the Finite-Difference Method in gas medium through applied electric field at 300 oK.
The theoretical predictions were obtained in agreement with the experimental values was publishered.
Keyword: CO2 lasers, Boltzmann Transport Equation, RF Discharges, Transport
coefficients, Plasma discharge, Drift velocity.
