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 …

This paper reviews the research on the reversed field pinch (RFP) in the last three decades.
Substantial experimental and theoretical progress and transformational changes have been …

This paper discusses the behaviour and consequences of the expected populations of
energetic ions in ITER plasmas. It begins with a careful analytic and numerical consideration …

Super-thermal ions and electrons occur in both space and fusion plasmas. Because these
energetic particles (EP) have large velocities, EP orbits necessarily deviate substantially …

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 …

The collective Thomson scattering (CTS) diagnostic proposed for ITER is designed to
measure projected 1D fast-ion velocity distribution functions at several spatial locations …

We present the first measurement of a local fast-ion 2D velocity distribution function f (v||,
v⊥). To this end, we heated a plasma in ASDEX Upgrade by neutral beam injection and …

Phase-space time-resolved measurements of fast-ion losses induced by edge localized
modes (ELMs) and ELM mitigation coils have been obtained in the ASDEX Upgrade …

A simple model for the instrument function of scintillator-based fast-ion loss detectors (FILD)
has been developed which accounts for the orbit trajectories in the 3D detector geometry …
