Investigation of electron Bernstein wave (EBW) coupling and its critical dependence on EBW collisional loss in high-?, H-mode ST plasmas

Original language description

The electron Bernstein wave emission (EBE) diagnostics and modelling have been employed on the National Spherical Torus Experiment (NSTX) to study oblique EBW to O-mode (B?X?O) coupling and propagation in H-mode plasmas. EBE simulations show that EBW collisional damping prior to mode conversion (MC) in the plasma scrape off reduces the coupling efficiency during the H-mode. Lithium conditioning increased the measured B?X?O coupling efficiency from less than 10% to 60%, consistent with EBE simulations.
