摘要:

在过去的十年中,尘埃颗粒污染越来越成为聚变研究界关注的一个领域。在国际热核聚变实验反应堆(ITER)这样的燃烧等离子体机器设计中,灰尘污染给诊断集成带来了问题,并可能导致氚安全问题。另外,由于ITER的设计,由于灰尘/壁的相互作用以及由这种颗粒在等离子体内产生的可能的不稳定性,预计这种灰尘污染问题将变得更加令人担忧。由于这种尘埃的动力学一般可以解释采用的离子阻力,库仑力和离子鞘前漂移的组合,最近的研究在复杂的(尘埃)等离子体物理往往提供了独特的见解,这一研究领域。本文将讨论如何在GEC射频参考电池的灰尘和等离子体参数的实验观测可能被用来诊断条件聚变反应堆内,希望提供深入了解可能的机制灰尘检测和清除的可能性。

英文摘要:

Over the past decade, dust particulate contamination has increasingly become an area of concern within the fusion research community. In a burning plasma machine design like the International Thermonuclear Experimental Reactor (ITER), dust contamination presents problems for diagnostic integration and may contribute to tritium safety issues. Additionally due to ITER design, such dust contamination problems are projected to become of even greater concern due to dust/wall interactions and possible instabilities created within the plasma by such particulates. Since the dynamics of such dust can in general be explained employing a combination of the ion drag, Coulomb force, and ion pre-sheath drifts, recent research in complex (dusty) plasma physics often offers unique insights for this research area. This paper will discuss the possibility of how experimental observations of the dust and plasma parameters within a GEC rf Reference Cell might be employed to diagnose conditions within fusion reactors, hopefully providing insight into possible mechanisms for dust detection and removal.
