In magnetic confinement plasma devices the hot central plasma is well separated from the surrounding first wall. Energetic particles can, however, still leave the confined plasma and interact with the surrounding materials. In addition electromagnetic radiation and neutrons created in a fusion plasma impinge onto the wall materials. The latter will influence material properties by causing atomic displacements as well as transmutation reactions within the wall materials.
Due to these harsh conditions modern high performance materials are already employed in present-day fusion devices to ensure a high operating efficiency.
The work performed in the frame of the project "Plasma Facing Materials And Components" addresses
- a more detailed understanding of the complex interaction processes between plasma and wall material,
- the development of new materials with further improved properties, and
- the integration of new materials into plasma facing components.
For this purpose the scientific-technical resources of IPP were brought together within this project.
