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 …

The excitation of collective instabilities by super-thermal particles in hot plasmas and the
related transport processes attract increasing interest due to their fundamental challenges …

Fast particles in fusion plasmas may drive Alfvén modes unstable leading to fluctuations of
the internal electromagnetic fields and potential loss of particles. Such instabilities can have …

Curvilinear guiding-centre drift and full-orbit equations of motion are presented as
implemented in the VENUS-LEVIS code. A dedicated interpolation scheme based on …

Energetic ions are found to be transported strongly from the core of MAST hybrid-like
plasmas during long-lived mode (LLM) magnetohydrodynamic activity. The resulting impact …

The high-beta capability of the spherical tokamak, coupled with a suite of world-leading
diagnostics on MAST, has facilitated significant improvements in the understanding of …

We have developed a hybrid code GMEC: Gyro-kinetic Magnetohydrodynamics (MHD)
Energetic-particle Code that can numerically simulate energetic particle-driven Alfvén …

Alfvén eigenmodes may be important in driving fast particle transport in magnetic
confinement fusion devices, with potentially deleterious results. To explain and predict this …

The goal of magnetic confinement fusion research is to produce an economically viable
power reactor. This will require operation at finite plasma β, where for instance fast particle …

A new application of the VENUS code is described, which computes alpha particle orbits in
the perturbed electromagnetic fields and its resonant interaction with the toroidal Alfvén …
