Abstract

The generation of radial electric fields through radiofrequency has been investigated in a toroidal magnetized plasma without rotational transform. By launching different kinds of electrostatic waves the plasma profiles were modified and sheared electric fields were generated. Direct observation of sheared E x B flows driven by fluctuations via Reynolds stress at the resonance layer of ion Bernstein is reported. These experiments provide a new bridge between experimental measurements and theoretical models in understanding the underlying physics of improved confinement regimes using RF in magnetically confined plasmas. © 1999 IOP Publishing Ltd.
