Abstract:
The effects of an upper bound on the ionization frequency for a plasma slab irradiated with intense microwave power are investigated using a Chapman-function model. A quadrature algorithm is developed for the numerical computation of exact steady-state electron density profiles. The results for both stable and unstable profiles are analyzed in terms of a stability condition involving the deposition rate of microwave power. The dynamics of the electron distribution within the slab is treated approximately by constraining the density profiles to a sinusoidal form. A dynamical interpretation of stability then emerges from the approximate electron gain-loss equation. The stability problem is also formulated graphically by the introduction of a potential-like function. Steady-state characteristic curves for the plasma slab are calculated using sinusoidal density profiles typical contours of constant net electron gain rate are similarly presented. Author
