Trapping and retention of deuterium in plasma-irradiated carbonic materials

Trapping and retention of deuterium in the graphitized carbon composite CFC N11 and pyrolytic graphite PG99 under plasma irradiation were investigated using the technique of thermal desorption spectroscopy. In particular, it was shown that (1) deuterium is trapped even when the energy of irradiating...

Description
Summary:Trapping and retention of deuterium in the graphitized carbon composite CFC N11 and pyrolytic graphite PG99 under plasma irradiation were investigated using the technique of thermal desorption spectroscopy. In particular, it was shown that (1) deuterium is trapped even when the energy of irradiating ions approaches zero and in the case of electron irradiation’ (2) the doses being equal, trapping depends on irradiation duration’ and (3) the effect of temperature on trapping depends on the ion energy. Two mechanisms of deuterium trapping are considered. The observed regularities are explained by the peculiarities of their action in different conditions.
