Equilibrium and Instabilities / Proceedings of the Ninth Carolus Magnus Summer School on Plasma and Fusion Energy Physics

Instabilities of Alfvén Eigenmodes (AEs) are often excited by a super-Alfvénic population of fast ions accelerated with ion cyclotron resonance heating (ICRH) or produced by neutral beam injection (NBI) in present-day tokamaks. In view of the next-step burning plasma experiments with super-Alfvénic alpha-particles, the experimental data on AE instabilities is reviewed for large volume JET tokamak, high magnetic field C-MOD tokamak, and high-beta START and MAST tokamaks. The main types of AE instabilities are described and compared to theory.
