Collective contributions to the electric microfield distribution in a turbulent plasma

The electric microfield distribution for weakly turbulent electron-ion systems is calculated using an individual-collective approach. The possibility of separation into collective ion, collective electron, and individual contributions due to electrons and ions is discussed. Analytical expressions for the collective electron and the collective ion microfield distribution are presented in terms of the turbulent spectrum. The results for the total distribution in the case of ion-sound turbulence show significant deviations compared with those of plasmas in thermodynamic equilibrium.
