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 present status of zonal flow experiments is reviewed with the historical process to attain
the concept of zonal flows, which provides a new framework for understanding turbulence …

Plasma profiles and flows in the low-and high-field side scrape-off-layer (SOL) regions in
Alcator C-Mod are found to be remarkably sensitive to magnetic separatrix topologies (upper …

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 novel mechanism for the generation and amplification of intrinsic rotation at the low-mode
to high-mode transition is presented. The mechanism is one where the net parallel flow is …

The turbulent convective flux of the toroidal angular momentum density is derived using the
nonlinear toroidal gyrokinetic equation which conserves phase space density and energy …

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 low temperature boundary layer plasma (scrape-off layer or SOL) between the hot core
and the surrounding vessel determines the level of power loading, erosion and implantation …

A new “Mirror Langmuir Probe” diagnostic, combined with a double-coil scanning magnetic
probe, is used to interrogate Alcator C-Mod's quasi-coherent mode (QCM) with …

Experimental results from NSTX indicate that the snowflake divertor (D. Ryutov, Phys.
Plasmas 14, 064502 (2007)) may be a viable solution for outstanding tokamak plasma …
