| Outline of Final Research Achievements |
It is important to identify fluctuation dynamics with multiple spatio-temporal scales entirely for clarifying turbulent transport phenomena in fusion plasmas. For that purpose, large global simulations of magnetized plasmas, especially for helical plasmas, have been carried out in this research. Numerical diagnostics on simulation data of 3-D turbulent fields reveal nonlinear interaction between multi-scale fluctuations in their dynamics. Extension of the model to include kinetic effects, introduction of 3-D equilibrium magnetic configuration, development of numerical diagnostics simulating experiments have been also carried out to contribute establishment of the basis for simulation researches.
