Integrated Modeling of Axisymmetric Mirrors at Realta Fusion

The modeling magnetic mirrors for experimental interpretation and fusion device design necessitates the development of a new integrated modeling framework capable of resolving a variety of multiscale phenomena. Realta Fusion is developing the first-of-its-kind “RealTwin” modeling suite to accomplish this task. The RealTwin includes simulation capabilities for kinetic transport (CQL3D-m), MHD equilibrium (Pleiades), EC (GENRAY-c) as well as radiofrequency (AORSA) heating, kinetic neutral transport for edge neutrals (KN1D-C) and beam neutrals (FIDASIM), kinetic stability (VPIC), and MHD stability (FLORA, NIMROD, MUG). The simulation models within the RealTwin are coupled together self-consistently and run in automated workflows using the Integrated Plasma Simulator (IPS).

We will demonstrate how we can use the RealTwin’s capabilities for machine learning aided kinetic equilibrium reconstruction in the Wisconsin High-Temperature Superconducting Axisymmetric Mirror (WHAM) experiment, the design of next generation fusion devices, and the understanding of both kinetic and MHD instabilities.
