This overview is an assessment of the gyrokinetic framework and simulations to compute
turbulent transport in fusion plasmas. It covers an introduction to the gyrokinetic theory, the …

An overview is given of physics differences between stellarators and tokamaks, including
magnetohydrodynamic equilibrium, stability, fast-ion physics, plasma rotation, neoclassical …

A global plasma turbulence simulation code, ORB5, is presented. It solves the gyrokinetic
electrostatic equations including zonal flows in axisymmetric magnetic geometry. The …

This paper generally compares the essential features between tokamaks and stellarators,
based on previous review work individually made by authors on several specific topics, such …

The current state of the EUTERPE code is described with emphasis on the implemented
models and their numerical implementation. The code solves the multi-species …

This document is the product of a stellarator community workshop, organized by the National
Stellarator Coordinating Committee and referred to as Stellcon, that was held in Cambridge …

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 …

A detailed description of GENE-3D, a newly developed global stellarator version of the well
established gyrokinetic turbulence code GENE, is provided–along with some initial …

Radial profiles of density fluctuations and the radial electric field, E r, have been measured
using Doppler reflectometry during the post-pellet enhanced confinement phase achieved …

Recent progress in the gyrokinetic theory of stellarator microinstabilities and turbulence
simulations is summarized. The simulations have been carried out using two different …
