人们早就知道，在聚变装置的等离子体中会出现微小的尘埃。最近有研究表明，粉尘可能是导致长时间放电终止的原因。此外，在iter规模的实验中，粉尘可能会带来与化学活性、氚保留和放射性含量相关的安全问题。特别是，ITER真空室中灰尘的存在是ITER许可程序的主要关注点之一。在这里，我们回顾了近年来在理解聚变等离子体中尘埃动力学和输运物理的不同实验和理论方面的进展，并讨论了尚待解决的问题。
It has been known for a long time that microscopic dust appears in plasmas in fusion devices. Recently it was shown that dust can be responsible for the termination of long- discharges. Also, in ITER-scale experiments dust can pose safety problems related to its chemical activity, tritium retention and radioactive content. In particular, the presence of dust in the vacuum chamber of ITER is one of the main concerns of the ITER licensing process. Here we review recent progress in the understanding of different experimental and theoretical aspects of the physics of dust dynamics and transport in fusion plasmas and discuss the remaining issues.
