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 …

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

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 …

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 1998 the four ITER parties decided to investigate a smaller and cheaper (50% cost)
machine design with reduced technical objective but without jeopardizing the programmatic …

The key result of the present work is the theoretical prediction and observation of the
formation of a new type of transport barrier in fusion plasmas, called F-ATB (fast ion-induced …

We study the simplest problem of turbulence spreading corresponding to the spatio-
temporal propagation of a patch of turbulence from a region where it is locally excited to a …

Significant reductions in the size and cost of a fusion power plant core can be realized if
simultaneous improvements in the energy replacement time,, and the plasma pressure or …

The differences and similarities between the internal transport barriers (ITBs) of tokamak and
helical plasmas are reviewed. By comparing the characteristics of the ITBs in tokamak and …

Experimental studies on radial structures of plasma rotation and radial electric field in
toroidal plasmas are reviewed. In this context, the perpendicular and parallel viscosities that …
