利用快速偏滤器相机观测到NSTX等离子体中与边缘局域模（ELM）相关的丝状结构。在偏滤器区的可见光发射中，ELMs总是发生丝状化。这些现象似乎是沿着磁场发生的。结果表明，偏滤器区的薄膜结构呈螺旋状，且为环向/极向非对称结构。强大的和众多的deletations观察到巨大的榆树，而长满草的榆树发生弱deletations。基于我们的测量，ELMs可以通过表征的数量和强度来区分。
Filamentary structures correlated with ELMs (Edge Localized Modes) in NSTX plasmas were observed by fast divertor camera. Filamentations always occurred with ELMs in the visible light emission in the divertor region. These filamentations appeared to occur along the magnetic field. It was found that the filamentary structures had a spiral pattern and were toroidal/poloidal asymmetric in the divertor region. Strong and numerous filamentations were observed with giant ELMs, whereas grassy ELMs occurred with weak filamentations. Based on our measurements, ELMs can be distinguished by the number and strength of filamentations.
