The ITER-Core Turbulent Plasma Diagnostics Based on the Synergy of Stimulated Raman and Brillouin Scattering

A novel plasma diagnostic method\footnote{ R. Prater et. al., APS-DPP-2009, (BAPS.2009.DPP.NO4.11); V. A. Stefan, APS-DPP-2019, GP10.00091}$^{\mathrm{,}}$\footnote{ Evgeny Pavlovich Velikhov, private (tel.) communication, May, 2019; V. Alexander STEFAN, \textit{Nonlinear Electromagnetic Radiation Plasma Interactions}, (S-U-Press, 2008). \par } is proposed based on the synergy of stimulated Raman and Brillouin scattering. A nonlinear electron-Bernstein mode is excited in a 4-wave parametric coupling$^{\mathrm{.}}$. The synergy between stimulated Raman and Brillouin scattering is analyzed. The scatterings off electron Bernstein mode is analyzed for the gyrotron frequency of 170GHz; X-Mode and O-Mode power of \quad 24 MW CW; on-axis B-field of \quad 10T.$^{\mathrm{\thinspace }}$The stimulated scattering in the electron cyclotron frequency range of the X-Mode and O-Mode driver with the ITER plasma lead to the appearance of suprathermal electrons and dragged by them accelerated ions at the plasma edge with the parameters directly dependent on the plasma parameters in the core of the ITER. Plasma diagnostic in the core region, (ion temperature), can be performed by the diagnostics of suprathermal electrons and accelerated ions at the edge plasma.
