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

[摘要] The erosion yield by deuterium impact was determined for various doped carbon-based materials. Ion beam bombardment with 30 and 200 eV at elevated temperatures (600-850 K) and low temperature plasma exposure with 30 eV ion energy (similar to 7 x 10(20) ions/m(2)s) and about 170 times higher thermal atomic deuterium flux at 300 K and 630 K were performed. The total yield of fine-grain graphites doped with 4 at.% Ti and Zr is reduced by a factor of 4 for 30 and 200 eV D impact at elevated temperatures at D fluences above 10(24) m(-2) compared to undoped graphite. Extensive carbide particle loss can be excluded up to fluences of similar to 10(25) m(-2). (C) 2010 Elsevier B.V. All rights reserved.
