ITER Plasma at Electron Cyclotron Frequency Domain: Stimulated Raman Scattering off Gould-Trivelpiece Modes and Generation of Suprathermal Electrons and Energetic Ions

Stimulated Raman scattering in the electron cyclotron frequency range\footnote{R. Prater et. al., APS-DPP-2009, (BAPS.2009.DPP.NO4.11).} of the X-Mode and O-Mode driver with the ITER plasma leads to the ``tail heating'' via the generation of suprathermal electrons and energetic ions. The scattering off Trivelpiece-Gould (T-G) modes is studied for the gyrotron frequency of 170GHz; X-Mode and O-Mode power of 24 MW CW; on-axis B-field of 10T. The synergy between the two-plasmon decay\footnote{ V. Alexander STEFAN, APS-DPP-2009, (K1.00028); APS-DPP-2010, (DPP10-2010-000167).} and Raman scattering is analyzed in reference to the bulk plasma heating.\footnote{ V.
