Classical transport theory for the collisional electronic [formula omitted] model

Abstract

The electronic M1 model is widely used for electron transport studies in a hot collisional plasma. However, the moment extraction of the electron–electron collision operator from the kinetic collision operator, for this angular moments model, is challenging and some approximations are required. In this work a characterisation of the electron–electron and electron–ion collision operators is given and the electron plasma transport coefficients are derived. It is shown that in the high Z limit the electronic M1 model and the Fokker–Planck–Landau equation coincide in the case of near equilibrium. Also, in general, the electron–electron collision operator proposed for the electronic M1 model recovers accurate electron transport plasma coefficients.
