Abstract Text:
The defining feature of the stellarator approach to magnetic fusion is that the plasma performance is determined by externally applied, carefully tailored, three-dimensional (3D) magnetic fields (Helander 2014; Boozer 2015). While the 3D nature of the configurations can increase the design complexity, it also allows sufficient freedom for optimization of the properties required in a stellarator fusion power plant. Type One Energy is pursuing optimization strategies to generate quasi-symmetric (QS) and quasi-isodynamic (QI) reactor-relevant stellarators. Employing the SIMSOPT (Landreman et al. 2021) and DESC (Dudt & Kolemen 2020) codes, the shape of the plasma boundary is modified within an optimization loop until a magnetohydrodynamic (MHD) equilibrium with desired properties is found. Targets for QI/QS quality, rotational transform, elongation, MHD stability, coil simplicity, turbulent transport, maximum-J, among others, are included in the optimization calculations. A database with 140,000 finite-pressure, fixed-boundary MHD equilibria has been generated that explores a broad region of design space with variations in field period (2 ⩽N ⩽ 6), aspect ratio (A = R/a, 5 ⩽ A ⩽ 11), rotational transform, and desired physics properties. This large dataset can be used to test the viability of commonly used proxies against more comprehensive theoretical models. In this work, we present potential designs being considered for Type One Energy’s Infinity Two, a Fusion Pilot Plant based on high field optimized stellarators.
