Nonlinear saturation of reverse shear Alfvén eigenmodes induced by kinetic electrons

A strong nonlinear saturation mechanism of the reverse shear Alfvén eigenmode (RSAE) induced by thermal electrons is observed in gyrokinetic ${\delta}f$ particle-in-cell simulation. This nonlinear effect occurs at moderate mode amplitude, $\delta B_{\perp}/B\lt 10^{-3}$ , and is associated with the...
