Project summary

The project aim is the investigation of parametric instabilities, nonlinear dissipative properties and turbulence in the rare plasmas, when the thermal electron mean free pass exceeds the spatial scale of plasma perturbations. In the direction of parametric instabilities the new description of the propagation and reflection of powerful radiation will be given for rare plasmas. As it is clear now, the theory of such plasmas will take into account electron-ion and electron-electron collisions of slow particles. The knowledge of such processes is necessary for the inertial nuclear fusion as well as for the research of the influence of powerful radiation on natural plasma formations. The study of the effect of the nonlinear inverse bremsstahlung absorption and radiation will be continued, the new processes of the multiple generation of harmonics and instabilities development, which is connected with excitation of the internal plasma fields, will be studied. These results are important for the research of the action of the laser radiation powerful pulses on the matter and necessary for the new physical branch of an ultra-short pulses action on plasma. While studying plasma turbulence the spectra of turbulent pulsation will be obtained and the anomaly of the transport in multi ion species plasma will be investigated. It is important to get such results because of real plasmas have a few spices of ions usually.
