Dynamics of shear Alfvén waves and energetic particles are crucial to the performance of
burning fusion plasmas. This article reviews linear as well as nonlinear physics of shear …

In toroidal magnetically confined plasmas, eigenmodes of Alfvén waves can be destablized
by energetic ions with velocities comparable to the Alfvén velocity. With the advent of …

Fast ions with energies significantly larger than the bulk ion temperature are used to heat
most tokamak plasmas. Fast ion populations created by fusion reactions, by neutral beam …

Superthermal energetic particles (EP) often drive shear Alfvén waves unstable in
magnetically confined plasmas. These instabilities constitute a fascinating nonlinear system …

The problem of modelling the self-consistent interaction of an energetic particle ensemble
with a wave spectrum specific to magnetically confined plasmas in a torus is discussed …

H modes with good confinement and small ELMs with the characteristics of type II or grassy
ELMs have been observed on ASDEX Upgrade. Such an ELM behaviour is essential to …

A scintillator based detector for fast-ion losses has been designed and installed on the
ASDEX upgrade (AUG) tokamak [A. Herrmann and O. Gruber, Fusion Sci. Technol. 44, 569 …

On the road to a fusion reactor, a thorough control of the fast-ion distribution plays a crucial
role. Fusion-born α α-particles are, indeed, a necessary ingredient of self-sustained burning …

Alpha-particle-driven toroidal Alfvén eigenmodes (TAEs) have been observed for the first
time in deuterium-tritium (DT) plasmas on the tokamak fusion test reactor (TFTR). These …

This Letter presents the first direct experimental measurements of the damping of toroidicity-
induced Alfvén eigenmodes (TAE), carried out in the JET tokamak. These measurements …
