A comprehensive review of zonal flow phenomena in plasmas is presented. While the
emphasis is on zonal flows in laboratory plasmas, planetary zonal flows are discussed as …

Tokamak discharges with improved energy confinement properties arising from internal
transport barriers (ITBs) have certain attractive features, such as a large bootstrap current …

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 …

ABSTRACT A major scientific success story of magnetic fusion research in the past several
decades has been the theoretical development and experimental testing of the process of …

This paper presents new measurements of the cross-phase angle, α ne T e⁠, between long-
wavelength (k θ ρ s< 0.5) density, n ̃ e⁠, and electron temperature, T ̃ e⁠, fluctuations in the …

The effect of a sheared toroidal velocity on a transport barrier is studied. This analysis is
done by using three-dimensional global fluid simulations of electrostatic ion temperature …

The common physics elements behind various transport barrier theories and simulations,
and the related experimental observations mainly from tokamaks, are discussed. These …

Continuous control over azimuthal flow and shear in the edge of the Large Plasma Device
(LAPD) has been achieved using a biasable limiter which has allowed a careful study of the …

The impact of fast ions, generated in the MeV-range through the efficient application of the
three-ion scheme in JET plasmas, on the turbulence properties is presented through …

The low-to-high confinement mode transition (L–H transition) is one of the key elements in
achieving a self-sustained burning fusion reaction. Although there is no doubt that the mean …
