Surface modification and hydrogen isotope retention in CFC during plasma irradiation in the Tore Supra tokamak

Deuterium trapping in carbon fiber composites exposed to D plasma

“…Based on our results, it is difficult to reveal the nature of these TDS peaks. However, a peak in the same temperature range was found in TDS spectra for CFC exposed to the air [5]. Thus, one can assume that relevant traps are also formed by the mechanism of 'potential trapping'.…”

“…It should be noted that inelastic low-energy interactions provides hydrogen trapping in some other cases. For example, hydrogen is trapped on the graphite surface at the expense of en- ergy of water molecule interaction with graphite in the course of air exposure [5].…”

Erosion of carbon fiber composites under high-fluence heavy ion irradiation

“…The problems of erosion of the CFC surface layers under light ion irradiation in thermonuclear devices [4,5] and under oxygen irradiation of the spacecrafts and rockets have been studied intensively [6]. The interactions of the heavier ions of the noble gases with carbon-carbon materials have been insufficiently investigated.…”
