Three dimensional quantitative estimation of blobby plasma transport in the edge region of the helical device

本文研究了大螺旋装置（LHD）边缘区的间歇等离子体输运，如滴状等离子体输运。从两个离子饱和电流信号和磁几何的分析，我们定量估计的理论假设的斑点传播速度和大小。在共振磁微扰辅助分离运行过程中，通过对多个偏滤器板的多点测量发现了强的环向不对称性。

We have investigated intermittent plasma transport such as the blobby plasma transport in the edge region of the Large Helical Device (LHD). From analyses of two ion saturation current signals and magnetic geometry, we quantitatively estimated blob propagation velocity and size on a theoretical assumption. During resonant magnetic perturbation assisted detached operation, strong toroidal asymmetry was found in the propagation characteristics by multi-point measurement on several divertor plates.
