Probability Density Function of Density Fluctuations in Cylindrical Helicon Plasmas
スポンサーリンク
概要
- 論文の詳細を見る
The turbulence fluctuation spectra of linear magnetized plasmas are measured under various neutral pressure conditions. Strong turbulent waves and symmetric waves are observed in low and high neutral pressure conditions. In this study, we compare the radial structure of the probability density function (PDF) of these fluctuations. The characteristics of the PDFs are related to those of the radial and poloidal turbulent structures.
