STEADYSTATE ELECTRON DENSITIES FOR IRRADIATED PLASMAS
Abstract
Steady state electron density profiles were calculated for diffusion- and recombination-controlled plasmas irradiated by an external source of electromagnetic flux. In the former case the internal electron generation caused by progressive beam absorption is balanced by electron diffusion across the plasma boundaries. In the second model the beam-stimulated electron growth is limited by recombination. The efficiency of electron diffusion and consequent wall recombination as a heat transfer process is calculated and found never to exceed 30%. Furthermore, the nonlinear diffusion model gives rise to a stability criterion below which no steady state electron configuration is possible.
