摘要：

A study is presented of the distribution functions of the fluctuations of the ion saturation current and floating potential measured by Langmuir probes in the edge plasma of the U-3M torsatron. It is shown that these C, distribution functions may be classified as stable Levy distributions. Using the percentile method, stable-distribution parameters, namely, the Levy index and the scale factor for different probe positions, are estimated. These parameters are quantitative characteristics of the intensity and intermittency of turbulence in the edge plasma of the torsatron. (C) 2003 MAIK "Nauka/Interperiodica".
