Abstract

Low-frequency fluctuations related with a radial electric field are investigated in a magnetized plasma produced by an electron cyclotron resonance. It is observed that flute mode fluctuations are predominantly excited in a range of positive electric fields and drift mode fluctuations are stabilized with an increase of the radial electric-field strength.
