Abstract

Electron-fluid perturbation fields of a field-reversed configuration plasma is investigated by assuming the source of a electromagnetic wave is the electron current fluctuation. Electron trajectories in the prescribed perturbation field are calculated, and the toroidal flow velocity and velocity distribution and estimated by the particle-in-cell method. It is found that electrons are heated and enhancement of the end-loss of electrons is observed when the perturbation field is present.
