The purpose of this study is to elucidate helium (He) retention behavior in tungsten (W) under simultaneous He and hydrogen (H) irradiation. Polycrystalline-W was irradiated by He⁺ and H₂⁺ simultaneously with the energy of 1.0 keV and 3.0 keV. He⁺ fluences were (0.5, 1.0, 10) × 10²¹ He⁺ m⁻² and H₂⁺ fluence was 1.0 × 10²² H⁺ m⁻²,respectively. After irradiation, He desorption behavior was investigated by high temperature thermal desorption spectroscopy (HT-TDS) in the temperature range of R.T.-1773 K. Micro-structure changes of W after irradiation were observed by TEM. It was found that simultaneous irradiation with different H₂⁺ energy significantly changed He retention behavior. 1.0 keV H₂⁺ suppressed the He bubble growth and no bubbles can be observed at room temperature. On the other hand, 3.0 keV H₂⁺ facilitated the formation of He bubbles and increased the He retention due to the additional damage introduction by energetic H₂⁺.

这项研究的目的是阐明在同时照射He和氢（H）的情况下钨（W）中的氦（He）保留行为。用He ⁺和H ₂ ⁺同时以1.0 keV和3.0 keV的能量辐照多晶-W 。He ⁺通量为（0.5，1.0，10）×10 ²¹ He ⁺ m ^-2，H ₂ ⁺通量为1.0×10 ²²  H ⁺ m ^-2，分别。辐照后，通过高温热脱附光谱法（HT-TDS）在RT-1773 K的温度范围内研究He的脱附行为。辐照后观察到的W的微观结构变化。发现同时用不同的H ₂ ⁺能量辐照会显着改变He的保留行为。1.0 keV H ₂ ⁺抑制了He气泡的生长，在室温下未观察到气泡。另一方面，由于高能H ₂ ⁺引入了额外的损伤，3.0 keV H ₂ ⁺促进了He气泡的形成并增加了He的保留。
