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 …

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 …

The Lawson criterion is a key concept in the pursuit of fusion energy, relating the fuel density
n, pulse duration τ or energy confinement time τ E, and fuel temperature T to the energy gain …

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 …

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 DIII-D tokamak evolved from the earlier Doublet III device in 1986. Since then, the facility
has undergone a number of changes including the installation of divertor baffles and …

Advanced tokamaks aim at improved confinement resulting from transport barriers in the
central region of low magnetic shear. Another goal of the advanced tokamak is steady state …

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 …

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 …
