Geodesic mode instability driven by electron and ion fluxes during neutral beam injection in tokamaks
Original language description
The effect of a minor concentration of energetic particles produced by parallel NB injection on Geodesic Acoustic Modes (GAM) spectrum is analyzed using fully kinetic equation. It is found that the GAM frequency is reduced by the effective mass renormalization due to that new energetic GAM appears with higher frequency. The electron current in combination with NB driven ion flow, modeled by shifted Maxwell distribution, may overcome the ion Landau damping thus resulting in the GAM instability when electron current velocity is larger than the effective parallel GAM phase velocity Rq omega Qualitative agreement of the theory with co/counter NB injection experiments in COMPASS tokamak is demonstrated.
