Nonlinear Saturation of Dissipative Trapped Ion Instability and Anomalous Transport

抄録

An expression for the turbulent collision frequency is derived by summing up the most dominant terms from each order in a perturbation expansion in order to obtain the nonlinear saturation level of the dissipative trapped ion instability. Numerical calculation shows that the anomalous diffusion coefficient at the saturated state is in good agreement with the result of Kadomtsev-Pogutse when the effect of ion Landau damping is taken into account.
