Análisis de inestabilidades two-stream en los casos límite de beam-plasma y gentle-bump en plasmas cinéticos no colisionales, usando algoritmos tipo Particle-in-Cell no relativistas

Abstract

A space plasma can be described analytically from a kinetic approach. In this regime, the behavior of the plasma is governed by one Vlasov equation for each of the species present in the plasma. This study has two components: one analytical and the other one numerical. In both scenarios, we analyze the two-stream instability, in the limit cases of beam-plasma and gentle-bump. For the non-linear treatment, we have implemented a Particle-in-Cell full-kinetic code on the HPC server of the Department of physics of Escuela Politécnica Nacional. The simulations results show that our code is stable and adequately reproduces the physics of these limit cases.
