在大型螺旋装置(LHD)上研制了一套高速切向观察真空紫外望远镜系统，用于研究边缘MHD活动。用这种诊断方法测量了极向/环向模数为m/n=1/1的低频(~0.75 kHz)MHD活动的空间结构。
A high speed tangentially viewing vacuum ultraviolet telescope system has been developed in the Large Helical Device (LHD), with the aim of investigating edge MHD activities. The spatial structure of low frequency (~0.75 kHz) MHD activity with poloidal∕toroidal mode numbers of m∕n = 1∕1 has been measured with this diagnostic.
