| Zusammenfassung |
| The intermittency of density fluctuations in the solar wind at kinetic scales has been examined using high time resolution Faraday cup measurements from the Spektr-R spacecraft. It was found that the probability density functions (PDFs) of the fluctuations are highly non-Gaussian over this range, but only show weak changes in shape with scale. Moreover, the multifractal spectrum evaluated at these scales show a moderate intermittency. These properties are compared to those of the magnetic fluctuations, and are important to understanding the dynamics of small scale turbulence in the solar wind. |
