2,5-DIMENSIONAL NUMERICAL SIMULATION OF PROPAGATION OF THE FINITE SEQUENCE OF RELATIVISTIC ELECTRON BUNCHES (REB) IN TENUOUS AND DENSE PLASMAS

摘要

Particle simulation results on the wake-field excitation with the programmed finite sequence of REB in tenuous and dense plasmas are presented. The REB/background plasma configuration is described by full set of 2D3V relativistic Vlasov equations for each plasma species and nonlinear Maxwell equations for self-consistent electromagnetic field. The physical parameters in runs carried out are close to those used in laboratory experiment at Kharkov IPT (Ya. Fainberg at all, 1994). The simulation points to the fact that the reached value of electric field depends on charge distribution and choice of intervals between bunches in programmed sequence.
