The understanding and prediction of transport due to plasma microturbulence is a key open
problem in modern plasma physics, and a grand challenge for fusion energy research. Ab …

This paper addresses non-linear gyrokinetic simulations of ion temperature gradient (ITG)
turbulence in tokamak plasmas. The electrostatic GYSELA code is one of the few …

A new conservative global gyrokinetic toroidal full-f five-dimensional Vlasov simulation
(GT5D) is developed using a novel non-dissipative conservative finite difference scheme …

The impact on turbulent transport of geodesic acoustic modes excited by energetic particles
is evidenced for the first time in flux-driven 5D gyrokinetic simulations using the Gysela code …

Critical physical issues can be specifically tackled with the global full-f gyrokinetic code
GYSELA. Three main results are presented. First, the self-consistent treatment of equilibrium …

We show in this paper that geodesic acoustic modes (GAMs) can be efficiently excited by a
population of fast ions even when Landau damping on thermal ions is accounted for. We …

The importance of using a comprehensive suite of tools for the validation of a gyrokinetic
code is described. This is detailed by presenting experimental wavenumber spectra which …

Additional electron cyclotron resonance heating (ECRH) is used in an ion-temperature-
gradient instability dominated regime to increase R/LT e in order to approach the trapped …

The mechanism for the formation and sustainment of a self-organized global profile and
the'E× B staircase'are investigated through simulations of a flux-driven ion temperature …

A cross-comparison and verification of state-of-the-art European codes describing gradient-
driven plasma turbulence in the core and edge regions of tokamaks, carried out within the …
