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

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 …

One of the scientific success stories of fusion research over the past decade is the
development of the E× B shear stabilization model to explain the formation of transport …

This is a textbook on theoretical plasma physics, which is the science of extremely hot gases
which make up most of the universe and which are used extensively in fusion energy …

A multi-species fluid model is described for the steady state parallel and radial force balance
equations in axisymmetric tokamak plasmas. The bootstrap current, electrical resistivity, and …

The suppression of turbulence by the E× B flow shear and parallel flow shear is studied in
an arbitrary shape finite aspect ratio tokamak plasma using the two point nonlinear analysis …

The method of Hammett and Perkins [Phys. Rev. Lett. 64, 3019 (1990) J to model Landau
damping has been recently applied to the moments of the gyrokinetic equation with …

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 …

The paradigm of shear suppression of turbulence as the mechanism for the low to high
confinement mode (L to H) transition is examined by quantitative comparison of the …

Turbulence simulations in diverted geometry across the edge and scrape-off layer (SOL) of
ASDEX Upgrade are performed with the GRILLIX code (Stegmeir et al 2019 Phys. Plasmas …
