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 …

The first experimental evidence showing the connection between blob/hole formation and
zonal-flow generation was obtained in the edge plasma of the JET tokamak. Holes as well …

A triggering mechanism responsible for the explosive onset of edge localised modes (ELMs)
in fusion plasmas is identified by performing, for the first time, non-linear …

Phase-space time-resolved measurements of fast-ion losses induced by edge localized
modes (ELMs) and ELM mitigation coils have been obtained in the ASDEX Upgrade …

A set of high frequency coherent (HFC) modes (f= 80–250 kHz) is observed with beam
emission spectroscopy measurements of density fluctuations in the pedestal of a strongly …

Edge localized modes (ELMs) are magnetohydrodynamic (MHD) instabilities that cause fast
periodic relaxations of the strong edge pressure gradient in tokamak fusion plasmas. A …

We review the current literature on the formation of coherent structures (CoSs) in strongly
turbulent 3D magnetized plasmas. CoSs [Current Sheets (CS), magnetic filaments, large …

An analytic solution for the expansion of a plasma into vacuum is assessed for its relevance
to the parallel transport of edge localized mode (ELM) filaments along field lines. This …

The ASDEX Upgrade tokamak has recently been equipped with a new filament probe for
filament studies. The probe features a set of radially separated Langmuir pins which are …

Drift-Alfvén vortex filaments associated with electromagnetic turbulence were recently
identified in reversed field pinch devices. Similar propagating filamentary structures were …
