This paper provides perspectives on recent progress in understanding the physics of
devices in which the external magnetic field is applied perpendicular to the discharge …

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 …

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 …

Self-consistent full-size turbulent-transport simulations of the divertor and scrape-off-layer
(SOL) of existing tokamaks have recently become feasible. This enables the direct …

The global drift-ballooning (GDB) code is developed to study tokamak edge low frequency
turbulence and transport, and their relationship to global profile evolution. The code employs …

A theoretical framework is developed to link the density profiles in the scrape off layer (SOL)
with the fluctuations (filaments) that generate them. The framework is based on the dynamics …

Developing accurate models of plasma dynamics is essential for confident predictive
modeling of current and future fusion devices. In modern computer science and engineering …

This paper outlines an approach towards improved rigour in tokamak turbulence transport
model validation within integrated modelling. Gaussian process regression (GPR) …

Transport processes around the magnetic X-point of tokamaks, such as turbulence and
mean-field drifts, are scarcely understood. The assessment of the capability of turbulence …

Four numerical codes are employed to investigate the dynamics of scrape-off layer filaments
in tokamak relevant conditions. Experimental measurements were taken in the MAST device …
