Effect of electron collisions on transport coefficients induced by the inverse bremsstrahlung absorption in plasmas
Abstract
The transport coefficients of fully ionized plasmas under the influence of a highfrequency electric field are derived solving numerically the electron FokkerPlanck equation using a perturbation method, parametrized as a function of the electron meanfreepath {lambda}{sub ei} compared to the spatial scales L. The isotropic and anisotropic contributions of the inverse bremsstrahlung heating are considered. Electronelectron collision terms are kept in the analysis, which allows us to consider with sufficient accuracy to describe plasmas with arbitrary atomic number Z. Practical numerical fits of the transport coefficients are proposed as functions of Z and the collisionality parameter {lambda}{sub ei}/L.
