Abstract
Operating with a high frequency and a wave guide antenna, the ion Bernstein wave (IBW) experiment on the Frascati Tokamak Upgrade is not dominated, as expected, by nonlinear plasma edge phenomena. By coupling IBW power, a sim ultaneous increase of plasma density and central electron temperature (grea ter than or equal to2 keV) is produced when the confinement magnetic field is adjusted to set an ion cyclotron resonant layer in the plasma bulk. Tran sport analysis indicates a reduction of the electron thermal transport insi de the internal resonant layer larger than a factor of 2. (C) 2001 American Institute of Physics.
