中文摘要：

为了为杂质的情形调查放射的 divertor 行为和物理，在 ITER 播种了血浆，有在象 ITER 一样钨 divertor 状况下面播种的氩(Ar ) 的放射的 divertor 实验在最近的东方运动期间被执行。试验性的结果揭示由播种的 Ar 由于增加的放射减少热负担和粒子流动到 divertor 目标上的高效率。我们在这些实验完成分开的血浆。在播种的 Ar 以后的内部外部的 divertor 不对称现象还原剂。杂质例如 Ar， C，李，和 W，在东方操作期间在真空房间的全部空格存在，并且在令人疲乏不堪的力量起重要作用并且加速血浆分开进程。核心血浆的污染用由于面对部件(陆军) 的血浆劈啪作响播种的 Ar 被观察，是显著的，特别地当 Ar 杂质从上面的钨 divertor 被注射时。

英文摘要：

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.
