- 論文の詳細を見る
A submillimeter wave scattering method was used to study low frequency, small scale, density fluctuations in plasmas and we have observed a microturbulence in a range of drift waves in the WT-1 and 2 tokamaks. The density fiuc-tuations are very intense (n^^~_e/n^^~_e〜 several percent). The wavenumber spectra have a peak at k_⊥ρ_s≃0.5 and are isotropic in the two-dimensional k_⊥ plane, where k_⊥ is the wavenumber perpendicular to the toroidal field B_T and ρ_s = (MT_e)^<1/2>/eB_T. The frequency spectra are very broad and the high frequency components are contained in an inner part of the plasma. Further, their intensity decreases and the frequency spectrum becomes narrow when the lower hybrid wave driven current is generated.
