Outline of Final Research Achievements

For deeper understandings on turbulent transport mechanism and prediction of transport properties, through quantitative analyses of plasma turbulence in Large Helical Device with non-axisymmetry, we have enhanced a research basis for the gyrokinetic simulation. The GKV code, which has been continuously extended from the present study, is currently applied to electromagnetic turbulence simulations for multi-species plasma with non-axisymmetry. In this study, we also promoted the entropy transfer analysis in non-axisymmetric configurations, and developed a flux tube train model. The obtained results contribute to advances of the gyrokinetic simulation studies of turbulent transport in non-axisymmetric plasmas.
