The physics of divertors in tokamaks is reviewed, primarily from an experimental point of
view, although where possible simple analytic modelling is included. The paper covers the …

The design, construction and operation of advanced divertors have been the main topics of
tokamak research during the last decade. The design of these divertors (carried out with two …

The H-mode is a confinement mode of toroidal plasmas, which may make the goals of fusion
possible—the development of a clean energy source at competitive electricity costs. The …

A review of measurements of microscopic fluctuations and theories of turbulence and
anomalous transport for tokamaks is given, and some comparisons between theory and …

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 …

A review of experiments and theory of electron cyclotron resonance heating (ECRH) and
current drive (ECCD) is presented. An outline of the basic linear theory of wave propagation …

Marked changes in the edge radial electric field E r and in the edge poloidal rotation velocity
v θ are important signatures of the LH transition in the DIII-D tokamak. Shear exists in E r and …

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 …

The structure of the edge radial electric field E r inferred from the poloidal rotation velocity is
compared with that of the particle and thermal transport barrier for H-mode plasmas in JFT …

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 …
