Effect of edge biasing on electrostatic fluctuations and particle transport in a nonfusion magnetoplasma

This paper concerns experiments about the role of a radial electric field on the plasma turbulence in a toroidal magnetoplasma, and the possibility of anomalous transport reduction through the application of external biasing potentials to the plasma edge. The experiments show, for positive applied bias potential, a progressive reduction of radial anomalous particle flux, as well as electrostatic fluctuations. Some results on statistical and spectral properties of plasma and density fluctuations are reported. (C) 2000 American Institute of Physics. [S1070-664X(00)02105-4].
