Popis: |
This paper gives an overview of recent results on the application of electron Bernstein waves for plasma heating and diagnostic purposes at the WEGA stellarator. By applying a two-step mode conversion process it was possible to reach over-dense argon and helium plasmas with central densities of above 0.97 × 1019 m−3 at a magnetic field strength of 0.5 T fully sustained by electrostatic Bernstein waves. An unexpected feature observed during the experiments was the detection of a strong increase of the radiation temperature associated with the existence of a super-thermal electron component in the keV-range during this heating period. |
