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 …

This paper reviews measurements of edge plasma turbulence in toroidal magnetic fusion
devices with an emphasis on recent results in tokamaks. The dominant feature of edge …

In this paper we review some theoretical aspects of the dynamics of the mesoscale filaments
extending along the magnetic field lines in the edge plasma, which are often called 'blobs' …

Experimental drift turbulence and zonal flow studies in magnetically confined plasma
experiments are reviewed. The origins of drift waves, transition to drift turbulence and drift …

A multidiagnostic approach, utilizing Langmuir probes in the midplane, X-point and divertor
walls, along with lithium beam and infrared measurements is employed to evaluate the …

Radial convection of isolated filamentary structures due to interchange motions in
magnetized plasmas is investigated. Following a basic discussion of vorticity generation …

Fluctuations and particle transport in the scrape-off layer of TCV plasmas have been
investigated by probe measurements and direct comparison with two-dimensional …

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 …

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 …

The mechanism for blob generation in a toroidal magnetized plasma is investigated using
time-resolved measurements of two-dimensional structures of electron density, temperature …
