Helium (He) plasma irradiation to tungsten leads to formation of He bubbles and fiberform nanostructures called fuzz on the surface. Although the fuzz growth condition and growth rate have been well investigated, deposition of W together with He ions can change the He effect significantly. For example, the deposition leads to large-scale structures such as nano-tendril bundles and mm-thick large-scale fiberform nanostructures. In this review, current understanding of deposition effects on He irradiation are summarized, and the influence to fusion devices is discussed mainly from the view point of arcing.

钨丝绒：沉积效应及其对聚变设备的影响

氦对钨的等离子体辐射导致形成He气泡和称为绒毛的纤维状纳米结构。尽管已经对绒毛的生长条件和生长速度进行了充分的研究，但是W与He离子的沉积可以显着改变He的影响。例如，沉积导致大规模结构，例如纳米卷须束和毫米厚的大规模纤维状纳米结构。在这篇综述中，总结了目前对He辐照沉积影响的理解，并主要从电弧的角度讨论了对融合装置的影响。
