Summary
Various materials – tungsten, beryllium, and fibre-reinforced graphites – exhibiting different advantages and disadvantages are under discussion as wall materials for the plasma vessel of fusion devices, particularly ITER. The properties of graphite were investigated in detail. One disadvantage here is the deposition of amorphous hydrocarbon layers on the vessel walls. This, however, can be prevented.
