为了研究ITER中杂质籽晶等离子体辐射偏滤器的行为和物理机制，在最近的EAST活动中，在类ITER钨偏滤器条件下进行了氩（Ar）籽晶辐射偏滤器实验。实验结果表明，由于Ar籽晶增加了辐射，降低了偏滤器靶上的热负荷和粒子通量的效率很高。我们在这些实验中获得了分离的等离子体。注入Ar后，偏滤器的内外不对称性减小。在EAST运行过程中，诸如Ar、C、Li和W的杂质存在于真空室的整个空间中，并且在功率消耗和加速等离子体分离过程中起重要作用。值得注意的是，观察到的核心等离子体的污染，由于等离子体面向组件（PFC）的溅射使用Ar播种，特别是当Ar杂质从上钨偏滤器注入。
To investigate the radiative divertor behavior and physics for the scenario of impurity seeded plasma in ITER, the radiative divertor experiments with argon (Ar) seeding under ITER-like tungsten divertor condition were carried out during recent EAST campaigns. The experimental results reveal the high efficiency of reducing heat load and particle flux onto the divertor targets owing to increased radiation by Ar seeding. We achieve detached plasmas in these experiments. The inner–outer divertor asymmetry reduces after Ar seeding. Impurities, such as Ar, C, Li, and W, exist in the entire space of the vacuum chamber during EAST operations, and play important roles in power exhausting and accelerating the plasma detachment process. It is remarkable that the contamination of the core plasma is observed using Ar seeding owing to the sputtering of plasma facing components (PFCs), particularly when Ar impurity is injected from the upper tungsten divertor.
