本文利用热脱附谱(TDS)和透射电子显微镜研究了辐照下氢在F82H中的俘获行为。样品首先在600°C用5keV的He+辐照，然后在RT下以0.5keV的能量额外照射D2+。其中一些样品还接受了相对较高的能量，He+离子的能量为1 MeV，D2+离子的能量为650keV。通过对辐照后的氢和氦的热脱附测量，观察到氦辐照后的氚脱附峰向更高的温度移动了约30K，这归因于氦气泡周围俘获的氢气。此外，再回火和未经氦辐照的样品上的热脱附测量也表明，潜伏存在的碳化物可能是氢在F82H中的潜在捕获位。
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 5keV He+at 600°C followed by the additional D2+irradiations with the energy of 0.5keV at RT. Some of the specimens were also irradiated with relatively higher energy of 1MeV for He+and 650keV for D2+ions. According to thermal desorption measurements of deuterium and helium after irradiations, deuterium desorption peak shift to higher temperatures of about 30K 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.
