Abstrakt: Fundamental investigations on EBW excitation, propagation and absorption are presented. In particular the OXB mode conversion and EBW current drive with 2.45 GHz EBWs are investigated and compared with modeling. High density operation with 28 GHz EBWs could be achieved at 0.5 T (2nd harmonic). This regime is characterized by a additional strongly supra-thermal electron distribution with energies >10 keV. These electrons were detected by measurement of the EBW emission and by X-ray detection. [ABSTRACT FROM AUTHOR]
