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 …

Operation with all tungsten plasma facing components has become routine in ASDEX
Upgrade. The conditioning of the device is strongly simplified and short glow discharges are …

ASDEX Upgrade has successfully started the second experimental campaign with a full
tungsten coverage of the plasma facing components and without using a boronisation for …

Power exhaust in future fusion devices is critical and operation with a detached divertor is
foreseen for ITER and DEMO. The evolution of detachment in nitrogen seeded H-mode …

Erosion and deposition were studied in the JET divertor during the first JET ITER-like wall
campaign 2011 to 2012 using marker tiles. An almost complete poloidal section consisting …

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 …

The transition of ASDEX Upgrade (AUG) from a graphite device to a full tungsten device is
demonstrated with a reduction by an order of magnitude in both the carbon deposition and …

The use of beryllium, carbon and tungsten as plasma-facing materials (PFMs) in ITER calls
for dedicated investigations on their behaviour under the expected particle and power loads …

Tritium retention constitutes an outstanding problem for ITER operation and future fusion
reactors, particularly for the choice of the first wall materials. In present day tokamaks, fuel …

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 …
