Compilation of erosion yields of metal-doped carbon materials by deuterium impact from ion beam and low temperature plasma

The erosion yield by deuterium impact was determined for various doped carbon-based materials. Ion beam bombardment with 30 and 200eV at elevated temperatures (600–850K) and low temperature plasma exposure with 30eV ion energy (∼7×1020ions/m2s) and about 170 times higher thermal atomic deuterium flux at 300K and 630K were performed. The total yield of fine-grain graphites doped with 4at.% Ti and Zr is reduced by a factor of 4 for 30 and 200eVD impact at elevated temperatures at D fluences above 1024m−2 compared to undoped graphite. Extensive carbide particle loss can be excluded up to fluences of ∼1025m−2.
