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 …

Internal transport barriers in tokamak plasmas are explored in order to improve confinement
and stability beyond the reference scenario, used for the ITER extrapolation, and to achieve …

Three-dimensional gyrokinetic simulations of microturbulence in magnetically confined
toroidal plasmas with massively parallel computers showed that, with linear flow damping …

The understanding and predictive capability of transport physics and plasma confinement is
reviewed from the perspective of achieving reactor-scale burning plasmas in the ITER …

In this report we present a time-explicit, Eulerian numerical scheme for the solution of the
nonlinear gyrokinetic-Maxwell equations. The treatment of electrons is fully drift-kinetic …

The dependence of magnetohydrodynamic MHD stability limits on tokamak plasma shape is
well known and long studied both theoretically and experimentally. The dependence of …

This paper presents a complete theoretical framework for studying turbulence and transport
in rapidly rotating tokamak plasmas. The fundamental scale separations present in plasma …

A prime goal in physics research is the development of theories which have the universality
needed to explain a wide range of observations. Developed over the past decade, the …

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 …

The shear in the mean field velocity Doppler shift is shown to suppress the amplitude of
electric potential fluctuations by inducing a shift in the peak of the radial wave number …
