| 内容記述 | Nonlinear simulations of NTM with single helicity are performed. The time evolution of electromagnetic energy in case with different Fourier mode number is investigated. It is found that high-n mode accelerates the nonlinear evolution of (2,1) mode, and quasi-linear effect generated by (2,1) mode is important in saturation phase. Next, we investigated the structure of island in the cases with 2 and 8 Fourier modes. In both cases, the fluctuating bootstrap current are negative inside the island. These results are different from the assumption in the modified Rutherford theory for NTM. As a future work, NTM with multi-helicity modes will be performed. |
