Low-frequency fluctuations of the Ohmically heated plasma in the Proto-Cleo torsatron
Description
Low-frequency (f<500 kHz), turbulent density fluctuations have been observed in the Ohmically heated plasma of the Proto-Cleo torsatron. The power density spectrum indicates a spectral decay of the form fsup(-2.5) with no coherent modes present in the observed band. Phase spectral characteristics indicate wave number estimates which vary in magnitude and direction consistent with drift-wave phenomena. Parallel wave numbers are coupled proportionally to the shear. (author)
