Three-dimensional modeling of kinetics of electron-proton plasma with supercritical density in an powerful electromagnetic field of laser radiation (Q2788880)

The paper is a continuation of previous work by the authors [ibid. 26, No. 10, 79--94 (2014; Zbl 1324.78004)]. Kinetic functions of electron and proton distributions as functions of the time can be determined by using numerical methods to solve the 3D Maxwell-Vlasov equations describing the interaction of a power electromagnetic field of laser radiation with the electron-proton plasma. An analysis of the kinetic functions found gives the possibility to understand the mechanism of the most important effect of the mentioned interaction, i.e., the effect of proton acceleration until a sufficiently high energy level. It is found that the mechanism consists of a process of delivery on the proton component of the plasma of an impulse of the incident electromagnetic wave, increased by a reflection effect.
