In this paper, the theory of collisional and turbulent transport of impurities in tokamak
plasmas is reviewed. The results are presented with the aim of providing at the same time a …

This paper presents the current state of the global gyrokinetic code Orb 5 as an update of the
previous reference (Jolliet et al., 2007). The Orb 5 code solves the electromagnetic Vlasov …

Magnetic confinement fusion offers the promise of sustainable and safe energy production
on Earth. Advanced experimental scenarios exploit the fascinating yet uncommon ability of …

Many problems encountered in plasma physics require a description by kinetic equations,
which are posed in an up to six-dimensional phase space. A direct discretization of this …

We show that a class of near-marginal and low-collisional magnetised plasmas naturally
evolve into a globally organised state dubbed the'$\mathbf {E}\times\mathbf {B} $ staircase' …

Aiming to fill a corresponding lack of sophisticated test cases for global electromagnetic
gyrokinetic codes, a new hierarchical benchmark is proposed. Starting from established test …

This article presents an optimized and scalable semi-Lagrangian solver for the Vlasov–
Poisson system in six-dimensional phase space. Grid-based solvers of the Vlasov equation …

The software stack under development within a European coordinated effort on tools for
burning plasma modelling is presented. The project is organised as a Task (TSVV Task 10) …

In absence of external torque, plasma rotation in tokamaks results from a balance between
collisional magnetic braking and turbulent drive. The outcome of this competition and …

A model of E× B staircases is proposed based on a wave kinetic equation coupled to a
poloidal momentum equation. A staircase pattern is idealized as a periodic radial structure …
