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 development of reduced models provide efficient methods that can be used to perform
short term experimental data analysis or narrow down the parametric range of more …

In this paper we report on the implementation and verification of a phase-space resolved
energetic particle (EP) transport model. It is based on a first-principle theoretical framework …

In the late 1990s, fusion scientists at the Japanese tokamak JT-60U discovered abrupt large-
amplitude events during beam-driven deuterium plasma experiments. A large spike in the …

In DT plasmas, toroidal Alfvén eigenmodes (TAEs) can be made unstable by the alpha
particles resulting from fusion reactions, and may induce a significant redistribution of fast …

Shear Alfvén wave (SAW)/drift Alfvén wave (DAW) fluctuations can be destabilized by
energetic particles (EPs) as well as thermal plasma components, which play a key role in the …

The most efficient and promising operational regime for the International Thermonuclear
Experimental Reactor tokamak is the high-confinement mode. In this regime, however …

New regimes of Alfvén eigenmode (AE) induced fast ion transport in tokamak plasmas are
reported, in which microturbulence plays the role of a mediator of fast ion relaxation …

In a tokamak fusion reactor operated at steady state, the equilibrium magnetic field is likely
to have reversed shear in the core region, as the noninductive bootstrap current profile …

Linear and nonlinear modelling of Alfvénic instabilities, most notably toroidal Alfvén
eigenmodes (TAEs), obtained by using the global nonlinear electromagnetic gyrokinetic …
