Publikováno v: Contributions to Plasma Physics. 50:785-789

On WEGA stellarator electron Bernstein waves have been applied for plasma heating. The excitation of the electrostatic Bernstein waves was possible due to an efficient two-step OXB mode conversion process from electromagnetic waves. Overdense plasma

Autor: H. Faugel, V. Bobkov, H. Eixenberger, Y. Podoba, I. Stepanov, null ASDEX Upgrade Team

Publikováno v: AIP Conference Proceedings

The ICRF system at ASDEX Upgrade has proved to be very flexible in use, from high power heating down to moderate or low power levels needed for vessel conditioning. As a consequence of these wide varieties of applications the present capabilities of
