| 摘 要： | 核聚变能是最有希望的一种新能源,我国自行设计与建造的核聚变装置——HL-1已于1985年投入运行。研究核聚变装置中等离子体与器壁、孔栏材料相互作用日益受到广泛重视,因为这种反应造成等离子体的污染及聚变装置材料灼损坏。同时,这一研究还将提供等离子体边界层的性能参数,为下一代装置的器壁材料选择和结构设计提供参考。本文研究了镍基合金和铝探针在HL-1装置的等离子体括削层内,经等离子体辐照后的表面形貌及表面组分的变化。

| Abstract: | Material probes made of inconel (GH39, 0.3mm) and aluminum (LFM, 0.5mm) were attached onto the surface of a movable limiter in the HL-1 tokamak.After exposure to 105 TDC and 400 tokamak discharges,areas ablated by unipolar arcing were left on the surface of both probes. Molybdenum, niobium and nickel were deposited onto the surface of the aluminum probe. The implantation of hydrogen particles into both probes were indicated by SIMS profile analysis. |
