Figures of merit for stellarators near the magnetic axis
Matt Landreman
A new paradigm for rapid stellarator configuration design has been recently demonstrated, in which the shapes of quasisymmetric or omnigenous flux surfaces are computed directly us…
Single-stage gradient-based stellarator coil design: Optimization for near-axis quasi-symmetry
Andrew Giuliani, Florian Wechsung, Antoine Cerfon +2
We present a new coil design paradigm for magnetic confinement in stellarators. Our approach directly optimizes coil shapes and coil currents to produce a vacuum quasi-symmetric ma…
Calculation of permanent magnet arrangements for stellarators: A linear least-squares method
Matt Landreman, Caoxiang Zhu
A problem arising in several engineering areas is to design magnets outside a volume that produce a desired magnetic field inside it. One instance of this problem is stellarator de…
The Use of Near-Axis Magnetic Fields for Stellarator Turbulence Simulations
R. Jorge, M. Landreman
The design of turbulence optimized stellarators has so far relied on three-dimensional equilibrium codes such as VMEC in order to find the minimum of a given objective function. In…
Magnetic well and Mercier stability of stellarators near the magnetic axis
Matt Landreman, Rogerio Jorge
We have recently demonstrated that by expanding in small distance from the magnetic axis compared to the major radius, stellarator shapes with low neoclassical transport can be gen…
A New Optimized Quasihelically SymmetricStellarator
A. Bader, B. J. Faber, J. C. Schmitt +12
A new optimized quasihelically symmetric configuration is described that has the desir-able properties of improved energetic particle confinement, reduced turbulent transportby 3D…
