Interactions between the plasma and the vessel walls constitute a major engineering
problem for next step fusion devices, such as ITER, determining the choice of the plasma …

Management of tritium inventory remains one of the grand challenges in the development of
fusion energy, and the choice of plasma-facing materials is a key factor for in-vessel tritium …

JET underwent a transformation from a full carbon-dominated tokamak to a fully metallic
device with beryllium in the main chamber and a tungsten divertor. This material …

A present topic of high interest in magnetic fusion is the “gap” between near-term and long-
term concepts for high heat flux components (HHFC), and in particular for divertors. This …

After completion of the tungsten coating of all plasma facing components, ASDEX Upgrade
has been operated without boronization for 1 1/2 experimental campaigns. This has allowed …

Tungsten is the plasma-facing material of choice in several design studies for DEMOs and in
development programs for advanced plasma facing components. Use of tungsten in ITER for …

Since 1999 ASDEX Upgrade increased its tungsten plasma-facing components (PFCs) and
finally reached a full W coverage in 2007. Most of the initial goals of the investigations were …

The efficacy of boron powder injection as a wall conditioning tool method in terms of its
ability to create a sufficiently uniform boron layer on plasma-facing surfaces has been …

For the design and operation of large fusion devices, a detailed understanding of the power
exhaust processes is necessary. This paper will give an overview of the current research on …

Net erosion and deposition of tungsten (W) in the ASDEX Upgrade divertor were determined
after the 2007 campaign by using thin W marker stripes. ASDEX Upgrade had full-W plasma …
