Some surface effects of (D, T) neutrons on candidate fusion reactor materials

Description

Measurements of fast neutron sputtering ratios for (D, T) neutrons incident upon metal foils are reported. Upper limits for forward sputtering of 4 x 10-4, 4 x 10-4 and 8.3 x 10-4 atoms/ (D, T) neutron have been determined for single crystal Nb, annealed Nb and cold worked Nb respectively. Sputtering ratios for emission of radioactive daughter atoms following (D, T) neutron induced reactions are reported for Nb, Au, Ti, Cu and V. Preliminary values of the sputtering ratio for Au are reported and these are lower than most previous results. A careful search for neutron sputtered micron sized particles yielded negative results. Some implications of radioactive atoms ejected from the walls of fusion reactors are discussed
