氦离子辐照钨和其他金属的效应已被广泛研究，作为离子能量，温度和注量的函数，在广泛的燃烧等离子体条件下，不仅使用离子加速器，而且使用大型等离子体约束装置，如TRIAM-1 M和LHD。本文综述了氦等离子体辐照下钨材料的起泡、腐蚀和其它辐照效应，如内部损伤演化、力学性能和耐热性的变化，以及与中子辐照的协同效应等方面的最新研究结果，以更好地理解氦等离子体辐照下钨材料的性能。强调了在燃烧等离子体条件下，氦辐照对钨作为等离子体面对材料是一个严重的问题。(c)2004 Elsevier B. V.保留所有权利。
Effects of helium ion irradiation for tungsten and other metals have been studied extensively as functions of ion energy, temperature and fluence, for a wide range of burning plasma conditions, using not only ion accelerators, but also large-sized plasma confinement devices such as TRIAM-1M and LHD. In this paper, recent results on blistering, erosion and many other irradiation effects such as internal damage evolution, change of mechanical properties and heat load resistance, and synergetic effects with neutron irradiation, are comprehensively reviewed for better understanding of the performance of tungsten under helium plasma bombardment. It is emphasised that helium irradiation is a serious issue for tungsten as a plasma facing material under burning plasma condition. (c) 2004 Elsevier B.V. All rights reserved.
