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 …

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 …

A quasiperiodic Er oscillation at a frequency of< 4 kHz, much lower than the geodesic-
acoustic-mode frequency, with a modulation in edge turbulence preceding and following the …

The intermittent character of turbulent transport is investigated with Langmuir probes in the
scrape-off layer and across the separatrix of ASDEX Upgrade Ohmic discharges. Radial …

Abstract Theory-based scaling laws of the near and far scrape-off layer (SOL) widths are
analytically derived for L-mode diverted tokamak discharges by using a two-fluid model. The …

The formation of plasma blobs is studied by analyzing their trajectories in a gyrofluid
simulation in the vicinity of the separatrix. Most blobs arise at the maximum radial electric …

The reliability of Langmuir probe measurements for plasma-turbulence investigations is
studied on GEMR gyro-fluid simulations and compared with the results from conditionally …

Blob statistical characteristics across the separatrix of HL-2A tokamak plasma have been
studied using a reciprocating Langmuir five-probe array. The radial profile of inverse …

The edge and scrape-off layer (SOL) region of a tokamak plasma is considered, with
emphasis on sheared flow generation and the dynamics of blob-filaments. Both numerical …
