Description

Deuterium thermal desorption from fine grain graphite MPG-8 and carbon fiber composite NB31 after irradiation by plasma and ion beam and after loading from gas was investigated. It was observed that deuterium accumulation in the two materials was similar in the region of the fluence of 1022-4 x 1024 D+/m2, though NB31 retains about twice as much deuterons. The retention in MPG-8 reveals no saturation at high fluence and no flux dependence in the range of (0.5/3.5) x 1020 D+/m2s. The difference between polished and unpolished samples, as well as between samples kept in air for various times after irradiation, was within the experimental uncertainty. (author)
