Whistler Mode Radiation induced by Kinetic Alfven Waves in burning plasma driven by Nonlinear Force
Abstract: The emission of electromagnetic radiation in the whistler mode within burning plasma has been studied in the presence of low-frequency kinetic Alfven wave (KAW) turbulence. This process occurs through wave-particle interactions driven by a nonlinear force. The nonlinear force arises from the resonant interaction between ions and the modulated field, which leads to instabilities. Using a Maxwellian model for the particle distribution function, the ?uctuating parts of the ion distribution were obtained. These ?uctuations generate a nonlinear force. By applying the ion momentum equation and the ion continuity equation, a nonlinear dispersion relation for the whistler mode was derived that incorporates this force. The growth rate of the whistler mode was then estimated using experimental data from fusion devices. The results suggest that whistler mode instabilities can develop in burning plasma when kinetic Alfven wave turbulence is present.
