摘　　要：世界性能源短缺使得发展新能源成为必然。聚变能源技术作为新能源中效率最高的技术,近年来一直备受关注。辐射损伤问题是制约聚变能源技术发展的主要问题之一。文章综述了氦、氢等离子源对钨表面的辐照损伤过程中金属钨表面形貌的变化及其损伤产物。氢离子辐射和中子辐射均在钨表面产生大小不一的孔洞,孔洞的大小和密度与辐射强度和温度正相关。He离子辐射在钨表面产生无序纳米绒毛。钨具有很好的物理特性,是内衬壁材料的最佳选择。通过研究不同种类辐射对钨的损伤,总结数据并设计方案,可以减小辐射损伤带来的影响。The world energy shortage makes it necessary to develop new energy sources.The most efficient fusion energy technology among alternative energy sources has always been the focus of attention.Irradiation damage has become one of the main problems restricting the development of fusion energy technology.In this paper,the surface morphology changes and the damage products of tungsten surface irradiated by He and H plasma sources are reviewed.Both H ion irradiation and neutron irradiation produce holes of different sizes on the surface of tungsten.The size and density of holes are positively correlated with irradiation intensity and temperature.He ion irradiation produces disordered nanotendrills on the surface of tungsten.Tungsten has good physical properties and it is the best choice for lining wall materials.By studying the damage of different kinds of irradiation damage to tungsten and summarizing the data and designing a proper scheme,the influence of irradiation damage can be reduced.
