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 …

Fusion whole device modeling simulations require comprehensive models that are
simultaneously physically accurate, fast, robust, and predictive. In this paper we describe the …

Nonlinear gyrokinetic codes allow for detailed understanding of tokamak core turbulent
transport. However, their computational demand precludes their use for predictive profile …

Quasilinear turbulent transport models are a successful tool for prediction of core tokamak
plasma profiles in many regimes. Their success hinges on the reproduction of local …

In the European fusion roadmap, ITER is followed by a demonstration fusion power reactor
(DEMO), for which a conceptual design is under development. This paper reports the first …

Operation of DEMO in comparison to ITER will be significantly more demanding, as various
additional limitations of physical and technical nature have to be respected. In particular a …

The verification and calibration of a new quasi-linear transport model with a large database
of gyrokinetic turbulence simulations is presented in this paper. In a previous paper …

The neoclassical transport optimization of the Wendelstein 7-X stellarator has not resulted in
the predicted high energy confinement of gas fueled electron-cyclotron-resonance-heated …

The findings of an investigation into the properties of the three dimensional (3D) saturated
fluctuation intensity of the electric potential in gyrokinetic turbulence simulations is …

The 2D spectrum of the saturated electric potential from gyrokinetic turbulence simulations
that include both ion and electron scales (multi-scale) in axisymmetric tokamak geometry is …
