作为面向固体等离子体组件（PFC）的替代选择，流动的液体锂可以用作限制器或偏滤器PFC，并提供具有可接受的热去除和良好杂质控制的自修复表面。这样的系统可以改善等离子体性能，因此对未来的聚变装置具有吸引力。最近，一个连续流动的液体锂（FLiLi）限制器已成功地设计和测试在EAST超导托卡马克。实现了厚度<0.1 mm且流速约为2 cm 3 s-1的循环锂层。利用EAST装置的环向磁场，设计了一种新型的容器内电磁泵，可以可靠地控制锂液流速。流动的液体限制器被发现是完全兼容的各种等离子体的情况下，包括高约束模式等离子体加热较低的混合波或中性束注入。研究还发现，限制器的可控锂排放有利于减少再循环和杂质，降低偏滤器热通量，并在某些情况下提高等离子体储能，这预示着流动液态锂PFC在未来聚变装置中的良好应用。
As an alternative choice of solid plasma facing components (PFCs), flowing liquid lithium can serve as a limiter or divertor PFC and offers a self-healing surface with acceptable heat removal and good impurity control. Such a system could improve plasma performance, and therefore be attractive for future fusion devices. Recently, a continuously flowing liquid lithium (FLiLi) limiter has been successfully designed and tested in the EAST superconducting tokamak. A circulating lithium layer with a thickness of <0.1 mm and a flow rate ~2 cm3 s−1 was achieved. A novel in-vessel electro-magnetic pump, working with the toroidal magnetic field of the EAST device, was reliable to control the lithium flow speed. The flowing liquid limiter was found to be fully compatible with various plasma scenarios, including high confinement mode plasmas heated by lower hybrid waves or by neutral beam injection. It was also found that the controllable lithium emission from the limiter was beneficial for the reduction of recycling and impurities, for the reduction of divertor heat flux, and in certain cases, for the improvement of plasma stored energy, which bodes well application for the use of flowing liquid lithium PFCs in future fusion devices.
