Multi-scale interaction among neoclassical tearing mode and drift wave turbulence
Description
The multi-scale interaction among the neoclassical tearing mode (NTM) and the drift wave (DW) is investigated using 4-field reduced MHD equations including neoclassical electron viscosity. It is newly found that the fluctuating bootstrap current term in the Ohm's law gives rise to a new instability for δ'<0. The drift wave coupling stabilizes this instability. Our result indicates not only β and ν* but also the normalized ion skin depth δ or density profile is an important ingredient to consider the NTM dynamics. (author)
