论文摘要
在磁性限制融合实验中，将粒子和热通量减少到等离子体面向成分对于血浆和血浆材料界面的稳定条件至关重要。最近在Wendelstein 7-X Stellarator实验中发现了一种稳定且可再现的等离子体状态，其中几乎完全从材料表面中除去了热通量。同时还减少了粒子通量，从而可以减轻材料侵蚀。达到足够的中性压力，以维持该等离子体状态的密度控制稳定的颗粒排气。该制度可以保持长达28秒，并具有最小的反馈控制。
Reduction of particle and heat fluxes to plasma facing components is critical to achieve stable conditions for both the plasma and the plasma material interface in magnetic confinement fusion experiments. A stable and reproducible plasma state in which the heat flux is almost completely removed from the material surfaces was discovered recently in the Wendelstein 7-X stellarator experiment. At the same time also particle fluxes are reduced such that material erosion can be mitigated. Sufficient neutral pressure was reached to maintain stable particle exhaust for density control in this plasma state. This regime could be maintained for up to 28 seconds with a minimum feedback control.
