Description

The stability properties of both high (ω approx. ωA) and low (ω approx. ω*pi approx. ωti) frequency Alfven modes are discussed, and it is shown that a transition between the two branches occurs as either the core plasma or the energetic particle pressure is increased. Results from nonlinear numerical simulations indicate that, above the excitation threshold for the Energetic Particle Modes (EPM), a strong redistribution in the energetic particle source can take place, possibly leading to large particle losses.
