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 …

In addition to the operational limits imposed by MHD stability on plasma current and
pressure, an independent limit on plasma density is observed in confined toroidal plasmas …

The divertor of a tokamak reactor will have to satisfy a number of critical constraints, the first
of which is that the divertor targets not fail due to excessive heating or sputter-erosion. This …

The basic physics of the processes playing the most important role in divertor plasma
detachment is reviewed. The models used in the two-dimensional edge plasma transport …

Plasma-facing materials (PFMs) have to withstand particle and heat loads from the plasma
and neutron loads during reactor operation. For ITER knowledge has been accumulated by …

The first stable completely detached H-mode plasma in the full tungsten ASDEX Upgrade
has been achieved. Complete detachment of both targets is induced by nitrogen seeding …

Divertor detachment is explored on the TCV tokamak in alternative magnetic geometries.
Starting from typical TCV single-null shapes, the poloidal flux expansion at the outer …

Wendelstein 7-AS was the first modular stellarator device to test some basic elements of
stellarator optimization: a reduced Shafranov shift and improved stability properties resulted …

In this paper, a new experimental classification of divertor detachment in ASDEX Upgrade is
presented. For this purpose, a series of ohmic and L-mode density ramp discharges at …

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 …
