Description
A mechanism linking high-frequency microinstabilities and the low-frequency macrostability is proposed. The coupling is provided by the time-averaged force, ponderomotive force, of unstable high-frequency waves. Two specific examples of this phenomenon are discussed. It is shown that an α-particle loss-cone instability stabilizes the flute mode of an ignited, axisymmetric mirror plasma. In tokamaks, the ion-whistler instability, driven by an anisotropic population of energetic particles, stabilizes the internal kink mode for JET range of parameters
