The role of stable shear flow in suppressing turbulence and turbulent transport in plasmas
and neutral fluids is reviewed. Localized stable flow shear produces transport barriers …

After a general discussion of the experimental characteristics of the LH transition and
consideration of basic theoretical principles underlying models for it, this paper reviews the …

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 …

High-resolution charge-exchange recombination spectroscopic measurements of B 5+ ions
have enabled the first spatially resolved calculations of the radial electric field (E r) in the …

Transport is the outstanding physics issue in the quest for fusion by magnetic confinement.
In spite of the intrinsic difficulty, a great deal of progress has been made in the past 25 years …

Azimuthal flow is driven in the edge of the Large Plasma Device (LAPD)[W. Gekelman et al,
Rev. Sci. Instrum. 62, 2875 (1991)] through biasing a section of the vacuum vessel relative to …

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 …

A generic model for advection of a scalar by E× B flow with a linearly varying mean shows
that the cross phase factor in the transport flux is strongly reduced in the strong shear regime …

The regulation of turbulent transport by zonal flows is studied experimentally on a flux
surface of the stellarator experiment TJ-K. Data of 128 Langmuir probes at different toroidal …

Recently, quasi-stationary structures called E× B staircases were observed in gyrokinetic
simulations, in all transport channels [Dif-Pradalier et al. Phys. Rev. Lett. 114, 085004 …
