Mapping the space of quasisymmetric stellarators using optimized near-axis expansion
Mapping the space of quasisymmetric stellarators using optimized near-axis expansion
A method is demonstrated to rapidly calculate the shapes and properties of quasi-axisymmetric and quasi-helically symmetric stellarators. In this approach, optimization is applied to the equations of magnetohydrodynamic equilibrium and quasisymmetry, expanded in the small distance from the magnetic axis, as formulated by Garren & Boozer [ Phys. Fluids B, …
