Classical transport theory for the collisional electronic M1 model

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.
