摘要
Effect of scattering of high harmonic fast magnetosonic waves (HHFW) by low frequency plasma turbulence is investigated. Due to the similarity of the wavelength of HHFW to that of the expected low frequency turbulence in the plasma edge region, the scattering of HHFW can become significant under some conditions. The scattering probability increases with the launched wave parallel-phase-velocity as the location of the wave cut-off layer shifts toward lower density edge. The scattering probability can be reduced significantly with higher edge plasma temperature, steeper edge density gradient, and magnetic field. The theoretical model could explain some of the HHFW heating observations on NSTX.
