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 …

The area of energetic particle (EP) physics in fusion research has been actively and
extensively researched in recent decades. The progress achieved in advancing and …

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

Alfvén spectra in a reversed-shear tokamak plasma with a population of energetic ions
exhibit a quasiperiodic pattern of primarily upward frequency sweeping (Alfvén cascade) …

This paper describes advances made in the field of energetic-particle physics since the
topical review of Alfvén eigenmode observations in toroidal plasmas (Wong 1999 Plasma …

Toroidal Alfvén eigenmodes and a new class of modes, the Alfvén cascades, excited by
energetic ions are observed in the JET tokamak. Measurements of these Alfvén instabilities …

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 …

Abstract Recent EAST/DIII-D joint experiments on the high poloidal beta tokamak regime in
DIII-D have demonstrated fully noninductive operation with an internal transport barrier (ITB) …

The theoretical framework of the general fishbone-like dispersion relation (GFLDR),
presented and discussed in the Companion Paper [Phys. Plasmas 21, 072120 (2014)], is …
