Outline of Final Research Achievements

The formation of Internal Transport barrier (ITB) has a crucial key to achieve high-performance magnetically confined fusion plasmas, however, such a phenomena had not been reproduced by turbulent transport simulations based on the first principle. In this work, we have newly developed global toroidal gyrokinetic code GKNET (GyroKinetic Numerical Experimental Tokamak) and performed nonlinear flux-driven turbulence simulation with an external momentum source. As a result, we found that the radial mean electric field can be modulated by external momentum source, leading to ITB formation in which the ion thermal diffusivity decreases to the neoclassical transport level.
