- 論文の詳細を見る
The asymmetric power spectra of the density fluctuations in JIPP T-IIU plasma are observed by far-infrared (FIR) laser scattering using a newly developed dual homodyne detection system. The observed spectra have many common features with those observed in PLT, TFR and others by microwave scattering. The peak frequencies of the broad spectra are found to be about three times as large as those of electron diamagnetic drift evaluated from the plasma parameters. The discrepancy can be mainly accounted for by the Doppler shift due to the fluid rotation of plasma by E^^^→×B^^^→ drift. In addition, low frequency MHD activities are observed simultaneously for a low poloidal wavenumber.
