Abstract :
Plasma facing materials in a fusion reactor will suffer from both plasma fluxes and DT-neutron irradiations. Experimental investigations have been initiated aiming at assessment of the combined effect of high-level radiation damage and plasma induced erosion on these materials. Complex modeling studies were performed on the ion cyclotron and LENTA plasma simulator at Kurchatov Institute. Carbon materials and tungsten have been irradiated with 3–5 MeV ions to reach 1–10 dpa of radiation damage. The features of irradiated materials are described. Irradiated materials response to deuterium plasma (100–250 eV D+ ions) at fluence 1025 ion/m2 was studied. Deformation effect and surface microstructure modification have been observed. Evaluation of erosion rate indicated erosion enhancement for radiation-damaged materials.
