Geodesic acoustic modes (GAMs) are ubiquitous oscillatory flow phenomena observed in
toroidal magnetic confinement fusion plasmas, such as tokamaks and stellarators. They are …

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 …

The stellarator is a type of fusion energy device that—if properly designed—could provide
clean, safe, and abundant energy to the grid. To generate this energy, a stellarator must …

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 …

In this work, we compare gyrokinetic simulations in stellarators using different computational
domains, namely, flux tube (FT), full-flux-surface (FFS), and radially global (RG) domains …

Anomalous transport of particles, momentum, and heat is commonly observed in fusion
plasma experiments, and has been a central issue in magnetic fusion research for the last …
