Research Abstract

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.
