Abstract :
In the present work, the trapping behavior of deuterium in F82H under irradiation were studied by means of thermal desorption spectrometry (TDS) and TEM. The specimens were first irradiated with 5 keV He+ at 600 °C followed by the additional D 2 + irradiations with the energy of 0.5 keV at RT. Some of the specimens were also irradiated with relatively higher energy of 1 MeV for He+ and 650 keV for D 2 + ions. According to thermal desorption measurements of deuterium and helium after irradiations, deuterium desorption peak shift to higher temperatures of about 30 K were observed for the case with helium irradiations, which attributed to the deuterium trapped by a surroundings of the helium bubbles. In addition, it is also concluded from the thermal desorption measurements of deuterium on re-tempered and as-received specimens without helium irradiations that the latently existing carbides can acts as a potential trapping site for deuterium in F82H.
