| Outline of Final Research Achievements |
The formation of internal transport barrier, which acts as the shielding layer of particle and heat transport by suppressing turbulence, has a crucial key to achieve high-performance plasma confinement. In this study, by introducing more realistic electron model to our first-principle code GKNET, we evaluated the impact of electron dynamics on internal transport barrier formation. We found that internal transport barrier is formed without external momentum injection by selectively exciting turbulence related to electron dynamics. This is the first report for spontaneous formation in the world.
