长脉冲等离子体放电中的等离子体-壁相互作用是优化未来核聚变反应堆第一壁材料和偏滤器结构的重要问题。利用可见光电荷耦合器件（CCD）摄像机观察到了大螺旋装置（LHD）中离子回旋频率范围（ICRF）加热的长脉冲放电中垂直安装偏滤器板上的热点。两条明亮的细线也出现在偏滤器腿上。通过对离子回旋共振（ICRF）波加速质子在等离子体外围两层离子回旋共振（ICR）层上三维运动轨迹的分析，可以解释CCD相机的观测结果。
Plasma-wall interaction in long-pulse plasma discharges is an important issue for optimizing the first wall materials and divertor configurations for future nuclear fusion reactors. A visible charge coupled device (CCD) camera observed a hot spot on a vertically installed divertor plate in a long pulse discharge heated by ion cyclotron range of frequency (ICRF) in the large helical device (LHD). Two bright thin lines also appeared on a divertor leg. The analyses of the three-dimensional trajectory of protons accelerated by ICRF waves on two ion cyclotron resonance (ICR) layers in the plasma periphery can explain the observation of the CCD camera.
