The axisymmetric TARA central cell has been heated using aperture and double half turn ICRF antennas to produce stable plasma with ..beta.. less than or equal to 0.2%. Parameters suitable for startup of thermal barriers with n = 3.5 x 10/sup 12//cm/sup 3/ and Ti/sub perpendiculer/ approx. 30 eV have been reached. Hot electron plasmas with ..beta.. less than or equal to 15% are obtained in the TARA and Constance quadrupoles. Electron cyclotron instabilities are analyzed. A new scheme for single frequency drift pumping with stochasticity by ICRF is proposed. ICRF modulated at the electron bounce frequency is shown to yield stochastic parallel electron heating for thermal barriers.
