Abstract
The nonlinear energy cascade in a nonuniform magnetized plasma is studied by using a simple model allowing an analytical solution. The results are then confirmed by a more refined numerical investigation. It is shown that the propagation of moderate amplitude Alfven waves interacting with the background may result in the dissipation of the equilibrium energy much faster than its standard resistive timescale.File in questo prodotto:
