Abstract Text:
Type One Energy is developing two optimized stellarators: Infinity Two, a high-field DT stellarator fusion pilot plant, and Infinity One, a mid-scale stellarator demonstrating the key features of Infinity Two. Critical to the success of both devices is the realization of a manufacturable electromagnetic coil system capable of producing intricately shaped magnetic fields. Here, we discuss realistic candidate designs for both Infinity Series stellarators and outline the coil optimization and design strategies used to generate coil sets comprised of strictly non-planar, modular coils. The two devices present distinct engineering challenges due to differences in size and magnetic field strength. To address these challenges, we employ two-stage and single-stage nonlinear optimization procedures to generate filament coil representations. A combination of optimization and database-driven methods is then used to determine optimal winding pack orientations of finite coils based on a multi-filament model. These reduced finite coil representations serve as the basis for high-fidelity engineering analysis and assessment of the impact of finite coil effects on the magnetic configuration. A key takeaway from integrated design exercises is the importance of directly penalizing filament coil non-planarity, rather than relying solely on proxy complexity metrics, to more reliably produce simplified finite coil shapes.
