Nonlinear saturation of trapped electron instability
Abstract
We consider the effect of trapped electron instability turbulence on the dynamics of a typical mode. We find its effects are turbulence induced additional collision frequencies for the trapped electrons which are stabilizing. The resulting saturation level is found to be considerably smaller than previous estimates.
