A blob-filament (or simply “blob”) is a magnetic-field-aligned plasma structure which is
considerably denser than the surrounding background plasma and highly localized in the …

Edge-localized-modes (ELMs) are a ubiquitous feature of H-mode in tokamaks. When
gradients in the H-mode transport barrier grow to exceed the MHD stability limit the ELM …

This paper reviews current understanding of key physics elements that control the H-mode
pedestal structure, which exists at the boundary of magnetically confined plasmas. The …

This paper summarizes the status of the COMPASS tokamak, its comprehensive diagnostic
equipment and plasma scenarios as a baseline for the future studies. The former COMPASS …

Recent research in scrape-off layer (SOL) and divertor physics is reviewed; new and existing
data from a variety of experiments have been used to make cross-experiment comparisons …

Predicting plasma evolution within a Tokamak reactor is crucial to realizing the goal of
sustainable fusion. Capabilities in forecasting the spatio-temporal evolution of plasma …

Results on edge turbulence in periods separating edge localised modes (ELMs), ie inter-
ELM periods, in Mega-Amp Spherical Tokamak (MAST) are presented. It is shown through …

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 …

Numerical simulations of interchange turbulence in the scrape-off layer are performed in a
regime relevant for a specific L-mode Mega Ampere Spherical Tokamak (MAST) discharge …

The spherical torus or spherical tokamak (ST) is a member of the tokamak family with its
aspect ratio (A= R 0/a) reduced to A∼ 1.5, well below the normal tokamak operating range …
