Journal ArticleDOI
Zonal flows in plasma—a review
TL;DR: A comprehensive review of zonal flow phenomena in plasmas is presented in this article, where the focus is on zonal flows generated by drift waves and the back-interaction of ZF on the drift waves, and various feedback loops by which the system regulates and organizes itself.
Journal ArticleDOI
The role of the electric field in confinement
Kimitaka Itoh,Sanae I. Itoh +1 more
TL;DR: Theories of the electric field effect on toroidal plasma confinement are reviewed in this paper with the emphasis placed on recent progress in the areas of anomalous transport, structural formation and bifurcation, research which has been motivated by the discovery of improved confinement.
Journal ArticleDOI
Physics of zonal flows
Kimitaka Itoh,Sanae I. Itoh,Patrick Diamond,T.S. Hahm,Akihide Fujisawa,George Tynan,Masatoshi Yagi,Yoshihiko Nagashima +7 more
TL;DR: In this paper, new viewpoints and unifying concepts are presented, which facilitate understanding of zonal flow physics, via theory, computation and their confrontation with the results of laboratory experiment.
Journal ArticleDOI
Turbulence spreading into the linearly stable zone and transport scaling
TL;DR: In this paper, the authors studied the simple problem of turbulence spreading corresponding to the spatio-temporal propagation of a patch of turbulence from a region where it is locally excited to a region of weaker excitation or even local damping.
Journal ArticleDOI
Edge localized mode activity as a limit cycle in tokamak plasmas.
TL;DR: A model of edge localized modes in tokamak plasmas is presented and a limit-cycle solution is found in the transport equation (time-dependent Ginzburg-Landau type), which has a hysteresis curve for the gradient versus the flux.
