Full-Particle Simulation of Electromagnetic Waves Induced by Electron Motion in a Field-Reversed Configuration

Abstract

In this study, we perform full-particle simulation for field-reversed configuration plasma and observe fluctuations in the toroidal component of the electron current density. To verify the validity of the simulation, we examine the phase velocity of the vertical wave motion that exhibits several mesh sizes. Using spectrum analysis, we confirm that the peak of the oscillation power spectrum is close to the theoretical value of the electron plasma oscillation for an appropriate mesh size.
