The major increase in discharge duration and plasma energy in a next step DT fusion
reactor will give rise to important plasma-material effects that will critically influence its …

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 …

Nuclear fusion is one of the most attractive alternatives to carbon-dependent energy
sources. Harnessing energy from nuclear fusion in a large reactor scale, however, still …

The present status of zonal flow experiments is reviewed with the historical process to attain
the concept of zonal flows, which provides a new framework for understanding turbulence …

The paper is a review of investigations of the H-mode on ASDEX performed since its
discovery in 1982. The topics discussed are:(1) the development of the plasma profiles, with …

Abstract Effects of the plasma boundary can have a substantial influence on the behaviour of
the entire plasma in tokamaks. Progress in the field, particularly that over the last decade, is …

A new tokamak confinement regime has been observed on the Tokamak Fusion Test
Reactor (TFTR) where particle and ion thermal diffusivities drop precipitously by a factor of∼ …

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 …

A detailed comparison is made between the tearing-type modes observed in TFTR
supershot plasmas and the nonlinear, neoclassical pressure-gradient–driven tearing mode …

In this paper we summarize the present status of experimental tokamak confinement studies.
Under quiescent conditions, ion heat and impurity transport can be close to the neoclassical …
