Plasma-Wall Interaction - A Key Issue in Progress Towards Fusion Power Plants
Generating energy from fusion requires a plasma with a temperature of 100 million degrees. Strong magnetic fields are used to protect the wall of a fusion device
The interaction between the plasma and the wall materials in a fusion reactor is a key factor determining the lifetime of the wall components and thus the overall cost-effectiveness of the facility.
The "first wall" is the name given to the surface of the inner wall of a fusion reactor. This wall is in direct contact with the plasmy and is thus directly affected by the plasma and its constituents.
The large-scale fusion experiment ITER (Latin for "the way") is currently under construction in Cadarache in the south of France as part of an international cooperation
Forschungszentrum Jülich designed and constructed a divertor, which is part of the new first wall in the leading fusion experiment, JET - the "ITER-like wall".
