Abstract

Microturbulence is one of the primary physical mechanisms which limit energy confinement in magnetically confined plasmas. The investigation of turbulence control and suppression is a critical goal for the optimization and design of future tokamak fusion reactors. The impact of the fast ions generated by means of heating systems has been demonstrated to play a very important role on such plasmas by suppressing heat transport. Those studies were performed solving the Vlasov equation using the gyrokinetic code GENE. However, significant drawbacks in the modelling previously performed could limit such turbulence reduction. In this project, a particular aspect will be addressed: the interaction among electromagnetic fluctuations, thermal ion transport and fast ion transport which is driven by large scale plasma fluctuations of the type of MagnetoHydroDynamics (MHD). This is essential in the magnetically confined plasmas field, as the main goal of such plasmas is to generate enough fusion power and for that purpose the thermal pressure and the fast ion fast ion content must be maximized. Such analysis will help to find a coherent ion distribution function, calculated by means of a Monte-Carlo code, between the external heating and the thermal and fast ion transport obtained by means of kinetic simulations. Usually, such coherence has been neglected in previous studies about fast ion impact on thermal transport including electromagnetic effects.
