Abstract

Recent developments and tools integrated into the TAPaS code are presented, enabling realistic scenario simulations of particle dynamics within experimental tokamak magnetic equilibria. In particular, the enhanced capabilities of TAPaS enable seamless coupling with external simulations, provided the metric and equilibrium magnetic field of the external code are known. Coupling TAPaS with the gyro-fluid code FAR3d, the transport and losses of energetic particles (EPs) in the presence Alfvén eigenmodes (AEs) in DIII-D plasma discharge #159243 were investigated using simple initialization of energetic particles in phase space. Detailed analyses of prompt losses in the presence of collisions (and without it) were performed. Then, further analysis that involves including the total electromagnetic perturbations resulting from AEs activities was performed. The results indicate that, for the energies and the initial conditions considered here, the presence of AEs enhances the particle losses at the end of the different simulations conducted in this study.
