摘要	托卡马克装置中偏滤器的能量排除一直是磁约束核聚变中最迫切需要解决的关键问题之一,而辐射偏滤器运行模式可以有效降低托卡马克装置中偏滤器靶板的热流和粒子流。本文全面介绍了氖(Ne)作为注入杂质在ASDEX-Upgrade、JET、DⅢ-D、HL-2A、EAST等装置上取得的最新的重要结果,同时总结了Ne等杂质在碳、钨材料偏滤器下的不同表现。钨作为未来聚变装置偏滤器以及第一壁等的材料,有着很大优势,但杂质注入下存在钨杂质溅射及聚芯问题,所以还需进一步探索钨偏滤器与注入杂质的兼容性以满足ITER等装置的要求。
其他摘要	The power exhaust of tokamak divertors has always been one of the most urgent problems in the magnetic confinement fusion devices, and the radiative divertor operation can effectively reduce the heat flow and the particle flux flowing of the divertor target plates in the tokamak. In this paper, the latest important results of neon(Ne) as injection impurities on the devices such as ASDEX-Upgrade, JET, DⅢ-D, HL-2 A and EAST have been introduced, and the plasma performances with neon seeding for carbon and tungsten divertors are summarized. Tungsten has great advantages as the material for the divertor and the first wall of future reactors, but there is the problem of tungsten impurity sputtering and concentration in the core in the implantation of the impurities. Therefore, it is necessary to further explore the compatibility of the tungsten divertor and the implanted impurities to meet the requirements of the ITER and other devices.
