"Numerical simulation of the turbulence development at interaction of an electron beam with plasma"
Berendeev E.A., Vshivkov V.A., Efimova A.A., and Mesyats E.A.

The interaction of an electron beam with plasma is considered. The physical mechanism of interaction between plasma and a relativistic electron beam includes a resonant excitation of plasma oscillations and the occurrence of plasma density modulation, followed by electron scattering. The numerical simulation is based on the particle-in-cell (PIC) method. A parallel algorithm is implemented to solve the problem under consideration. Two supercomputing systems were used to perform a number of numerical experiments.

Keywords: plasma physics, beam instability, Vlasov equation, Maxwell's equations, particle-in-cell (PIC) method.
