Abstract
General expressions are derived for the time-averaged flow of kinetic energy and of kinetic momentum, valid in the second order approximation. While the time-averaged density of kinetic energy is constant in time, the time-averaged flow of kinetic energy is constant in space. Therefore, no deposition of energy in a plasma occurs, despite the fact that Landau damping in space takes place for stable plasmas. The constant value of the averaged flow of kinetic energy is given by the contribution of the undamped coherent free oscillations, while the spatial damping of the forced oscillations sets off the effect of the phase interference between forced and free oscillations. (J.U.) 9 refs.
