Recently, an experimental investigation of electrostatic and magnetic properties of plasma fluctuations has evidenced a strong relation between this so-called “onset” phenomenon and the growth of large-scale magneto-hydrodynamic (MHD) instabilities, with the features of helical kink modes, due to a violation of the Kruskal-Shafranov stability criterion. In this paper we present the first attempt of controlling and suppressing these instabilities, and the effects of the reduction of plasma fluctuations on the power balance of the system.

Abstract
Recently, an experimental investigation of electrostatic and magnetic properties of plasma fluctuations has evidenced a strong relation between this so-called “onset” phenomenon and the growth of large-scale magneto-hydrodynamic (MHD) instabilities, with the features of helical kink modes, due to a violation of the Kruskal-Shafranov stability criterion. In this paper we present the first attempt of controlling and suppressing these instabilities, and the effects of the reduction of plasma fluctuations on the power balance of the system.File in questo prodotto:
