Magnetic-fusion plasmas are complex self-organized systems with an extremely wide range
of spatial and temporal scales, from the electron-orbit scales (∼ 10− 11 s,∼ 10− 5 m) to the …

We describe a new version of GBS, a 3D global, flux-driven plasma turbulence code to
simulate the turbulent dynamics in the tokamak scrape-off layer (SOL), superseding the code …

A first-principles self-consistent model that couples plasma and neutral physics suitable for
the simulation of turbulent plasma behavior in the tokamak SOL is presented. While the …

The results of flux-driven, two-fluid simulations in single-null configurations are used to
investigate the processes determining the turbulent transport in the tokamak edge. Three …

The electric field in the Scrape-Off Layer (SOL) of fusion plasmas is a key quantity affecting
the local plasma transport and possibly also the overall plasma confinement. However, the …

A self-consistent model is presented for the simulation of a multi-component plasma in the
tokamak boundary. A deuterium plasma is considered, with the plasma species that include …

Collisionality is one of the key parameters in determining turbulent transport in the plasma
edge, regulating phenomena such as' shoulder formation', separation of scale lengths in the …

The impact of plasma shaping on tokamak scrape-off layer (SOL) turbulence is investigated.
The drift-reduced Braginskii equations are written for arbitrary magnetic geometries, and an …

In the present work, a Verification and Validation procedure is presented and applied
showing, through a practical example, how it can contribute to advancing our physics …

The L to H mode transition occurs at a critical power which depends on various parameters,
such as the magnetic field, the density, etc. Experimental evidence on various tokamaks …
