Abstract
A consistent theoretical description of the global plasma modes that are excited or suppressed by the presence of a high-energy particle population is given. The present analysis underlines the importance of a finite-energetic particle response in the limit of vanishing perturbation frequency in order to stabilize resistive modes responsible for the so-called ‘‘sawtooth’’ oscillations of the central region of the plasma column.Keywords
