Simulation of "electron beam – modulation instability of plasma oscillations" system

Abstract

The integration of "electron beam - plasma" model and the hybrid model of modulation instability of Langmuir waves in plasma was performed. The influence of models on each other is partly simulated through the parameter of absorption level and the energy conservation law. In the "electron beam - plasma" model, such absorption level was found, in which the dynamics of processes in both considered models is the closest comparing by the energy indicators. It was shown how to use the variable absorption value, which is calculated from the energy conservation laws of two models. Also the parameters of the multimode regime in the "electron beam - plasma" model were defined.
