    Abstract

    The plasma flow in the SOL is important for impurity migration. There are few measurements from the HFS main SOL. To study the flow in the HFS SOL of ASDEX Upgrade, methane was injected from a HFS valve. The ensuing carbon emission distribution was followed using a fast video camera and a spectrometer was used to determine the Doppler shift of the injected carbon. This was carried out in lower single null L-mode and H-mode for low and high density plasmas. To elucidate the coupling between the flow of the injected carbon and the actual deuterium flow, ERO simulations were utilized. A strong carbon and deuterium flow towards the lower inner divertor was observed for high density plasmas in the far SOL along with a shear in the flow profile.
