AbstractAbstract
[en] Density perturbations induced by MHD activity were studied with broadband and fixed frequency O-mode microwave reflectometry on ASDEX. The system operated in the frequency range 18-60 GHz, allowing to probe densities ne ∼ 0.4 - 4.5 x 1013 cm-3. By obtaining from the broadband raw data the average phase shift radial pattern corresponding to the (indisturbed) plasma profile and the component due to fluctuations, the radial distribution of the fluctuations could be determined. With fixed frequency measurements the detailed temporal evolution of MHD modes at specific density layers could be estimated from the power spectra of the detected signals. Here we report on results obtained in Lower Hybrid Current Drive (LHCD) scenarios, and in H-mode discharges. (author). 4 refs, 14 figs
