温德尔斯坦7-X(W7-X)，一个优化的星光仪，进行了它的第一个偏滤器操作。它使用岛式偏滤器概念来排放热量和颗粒。已经达到了高达1.5平方米的大湿润区域，显示了偏滤器概念的好处和非常有效的热通量传播。此外，随着SOL功率的增加，润湿面积出现正比例变化，这对于在高输入功率下运行是很重要的。湿润区的定义是基于热像仪对W7-X的3D结构的观察，并与其他机器的定义(例如托卡马克)进行了比较。
Wendelstein 7-X(W7-X), an optimized stellarator, conducted its first divertor operation. It uses an island divertor concept for the heat and particle exhaust. Large wetted areas of up to 1.5 m2 have been reached, showing the benefits of the divertor concept and very efficient heat flux spreading. Moreover, a positive scaling of the wetted area with increasing SOL power is observed, which is important for operations at high input power. A definition of the wetted area is made based on thermographic camera observations for the 3D structure of W7-X with comparability to the definitions of other machines (e.g. tokamaks).
