Alfvenicity to Damping: Computational Insights from IMAS FALCON Integration and beyond — •Virgil - Alin Popa, Philipp Lauber, and Thomas Hayward-Schneider — Max Planck Institute for Plasma Physics, Garching, Germany

Building upon the robust infrastructure given by the Energetic Particle Workflow, we have integrated a new actor into the IMAS (Integrated Modeling and Analysis Suite) compliant workflow. The name of the new computational tool is FALCON (Floquet ALfven CONtinuum code). The model focuses on the continuous spectrum of SAWs in the ideal magnetohydrodynamic (MHD) limit. A formula for mapping Alfvenicity (given by FALCON) and kinetic damping (given by LIGKA) was developed. For this, various ITER scenarios were used for obtaining and validating the mapping formula. Furthermore, the workflow has been able to achieve significant speed-up in calculating the global linear properties of modes by exploiting analytical features and equilibrium profile information. This is of great importance when integrating the workflow into a transport code, where computational time is important.
