The model of particles modes. II. Transition to a fishbone-like state triggered by global synchronization and energetic particles

A. Ghizzo

Résumé

The interplay between kinetic aspects induced by energetic particles on turbulence is analyzed with a simplified model of ion-temperature-gradient-driven turbulence in magnetically confined plasmas. These topics are presented within an unified Hamiltonian framework in light of a new approach based on global phase synchronization between trapped particle modes and energetic particle modes. Numerical experiments have been carried out to elucidate concepts and physical processes of transition to a fishbone-like state triggered by energetic particles.
