First experimental results of statistical properties of turbulence plasma fluctuations in the SPLM upgrade

Abstract:

Fluctuations of parallel flows, electron density and plasma potencial radial profiles have been investigated in the SLPM-upgrade. First results in SLPM-up are quite similar to those obtained in the former device. A non-gaussian character is also found in fluctuation-induced particle flux statistics. Preliminary results show non-similarity of PDF(ΓExB). From Mach number measurements subsonic flows (M<0.5) are found. The PDFs(M) are close to gaussian distribution. Dynamical coupling between radial transport and parallel flows is found. Similarities between PDFs measured in this machine with those of fusion plasmas, suggest that the transition from closed to open magnetic field lines is not an important element in order to interpret the structure of turbulence.
