We present a 3D MHD simulation of two merging flux ropes exhibiting self-generated and
self-sustaining turbulent reconnection (SGTR) that is fully 3D and fast. The exploration of …

The impact of an edge radial electric field on the particle orbits and the orbital spectrum in an
axisymmetric toroidal magnetic equilibrium is investigated using a guiding centre canonical …

Chirping Alfvén modes are considered as potentially harmful for the confinement of
energetic particles in burning tokamak plasmas. In fact, by changing their frequency, they …

This paper deals with helical self-organization in current-carrying toroidal pinches for the
magnetic confinement of fusion plasmas. We perform our study in the framework of 3D …

The concept of Lagrangian coherent structures (LCS) has been recently applied to complex
magnetic configurations in plasmas in order to find and characterize their main structural …

Frequency chirping of Alfvén modes, a phenomenon observed in tokamak fusion plasmas
driven by energetic particles (EPs), can result in significant losses of EPs. In this study, we …

Magnetic field line chaos occurs under the presence of non-axisymmetric perturbations of an
axisymmetric equilibrium and is manifested by the destruction of smooth flux surfaces …

Magnetic field line chaos occurs under the presence of non-axisymmetric perturbations of an
axisymmetric equilibrium and is manifested by the destruction of smooth flux surfaces …

We investigate the influence of the finite Larmor radius on the dynamics of guiding-center
test particles subjected to an E× B drift in a large aspect-ratio tokamak. For that, we adopt the …

In a pair of linked articles (called Papers I and II, respectively), we apply the concept of
Lagrangian Coherent Structures borrowed from the study of Dynamical Systems to chaotic …
