With ITER, the largest tokamak ever built, and the growing number of fusion energy startups
in the world, the need for numerical simulations has never been more crucial to progress …

Plasma 'blobs', which are localized enhanced density structures, have been widely
observed in the turbulent edge and scrape-off layer (SOL) of several tokamaks. They are …

A new version of GBS (Ricci et al.(2012)[27]; Halpern et al. J. Comput. Phys. 315 (2016) 388-
408; Paruta et al.(2018)[11]) is described. GBS is a three-dimensional, flux-driven, global …

Turbulence simulations in diverted geometry across the edge and scrape-off layer (SOL) of
ASDEX Upgrade are performed with the GRILLIX code (Stegmeir et al 2019 Phys. Plasmas …

Parametric decay instabilities (PDIs) lead to the generation of strong frequency-shifted
radiation when powerful X-mode polarized microwaves, injected for electron cyclotron …

To make predictions for and design fusion reactors, a multitude of physical processes must
be considered. In the edge and scrape-off layer (SOL), turbulent fluctuations intertwine with …

A new open source tool for fluid simulation of multi-component plasmas is presented, based
on a flexible software design that is applicable to scientific simulations in a wide range of …

Turbulent dynamics in the scrape-off layer of magnetic fusion devices is intermittent with
large fluctuations in density and pressure. Therefore, a model is required that allows …

This contribution presents the recent effort at CEA and French federation for fusion to
simulate edge plasma transport with the new code SOLEDGE3X. The latter can be used …

We report on the implementation of diverted magnetic equilibria in GBS and on first
simulations in this geometry. GBS is a simulation code used to evolve plasma turbulence in …
