Comparison of Turbulence in LHD and Tokamak Plasmas (image) National Institutes of Natural Sciences Share Print E-Mail Caption Comparison of turbulence in helical LHD plasma (left) and in tokamak plasma (right). In the red color area, strong eddies and waves are generated. In a deuterium plasma with large ion mass, the zonal flows are grinding eddies and waves into small sizes and suppressing turbulence. The zonal flow is formed more significantly in the case in which instabilities are weak (bottom).
