Three-dimensionel modeling of kinetics of electron-proton plasma with supercritical density in an powerful electromagnetic field of laser radiation

Numerical solution of the equations of Maxwell–Vlasov in a three-dimensional (3D) model of interaction of powerful electromagnetic field of laser radiation with a electron-proton supercritical density plasma gives kinetic distribution functions for electrons and protons versus time. In the present paper such kinetic is analyzed in detail, which makes it possible to elucidate the mechanism of important effect under consideration — effect of proton acceleration to very high energies to tens MeV. This mechanism consists of transfer to the proton component of plasma impulse of the incident electromagnetic wave, enhanced by reflection effect of this wave. Qualitatively these results are in accordance with the physical experiments, fulfilled in last decade. This paper also presents results of the calculation of the distribution of all (six) components of the electromagnetic field inside the plasma with due regard for to electroneutrality violations of the plasma. This work concerns the kinetic properties of the plasma and is a continuation of our previous works.
