Application of Fraunhofer-Diffraction Method for Measurements of Electron Density Fluctuations in Heliotron E
スポンサーリンク
概要
- 論文の詳細を見る
Electron density fluctuations in Heliotron E were measured using the Fraunhoferdiffraction method of a CO. laser radiation. The deduced dispersion relation wasfound to be consistent with the drift wave, Doppler-shifted by a poloidal rotationresulting from a radial electric field. The measured intensities of the fluctuations wereused to estimate the diffusion coefficient and particle confinement time, the latter (10ms) being the same order of magnitude as that obtained independently from laserfluorescence and plasma emission, both at the Balmer alpha line.[Fraunhofer-diffraction method, Heliotron E, drift wave, electron density fluc- ll tuation, particle confinement timel
