Description
We present preliminary experimental results of the first application of ECH power to plasmas confined in the heliac geometry. Employing up to kW at 2.45 GHz we have observed strong absorption at both the fundamental and second harmonic with either a helical or a shaped dipole antenna. Either peaked or broad radial density profiles were obtained, depending on the location of the resonant field layers. Breakdown at the second harmonic appears to require seeding by a fundamental produced plasma. Densities up to two orders of magnitude above O-mode cut-off are observed. (author). 4 refs, 6 figs
