Stellarator optimization for nested magnetic surfaces at finite and toroidal current
A. Baillod, J. Loizu, J. P. Graves +1
Good magnetic surfaces, as opposed to magnetic islands and chaotic field lines, are generally desirable for stellarators. In previous work, M. Landreman et al. [Phys. of Plasmas 28…
Magnetic fields with precise quasisymmetry for plasma confinement
Matt Landreman, Elizabeth Paul
Quasisymmetry is an unusual symmetry that can be present in toroidal magnetic fields, enabling confinement of charged particles and plasma. Here it is shown that both quasi-axisymm…
Stellarator optimization for good magnetic surfaces at the same time as quasisymmetry
Matt Landreman, Bharat Medasani, Caoxiang Zhu
A method is demonstrated to optimize a stellarator's geometry to eliminate magnetic islands and achieve other desired physics properties at the same time. For many physics quantiti…
Single-stage gradient-based stellarator coil design: stochastic optimization
Florian Wechsung, Andrew Giuliani, Matt Landreman +2
We extend the single-stage stellarator coil design approach for quasi-symmetry on axis from [Giuliani et al, 2020] to additionally take into account coil manufacturing errors. By m…
A neoclassically optimized compact stellarator with four planar coils
Guodong Yu, Zhichen Feng, Peiyou Jiang +3
A neoclassically optimized compact stellarator with simple coils has been designed. The magnetic field of the new stellarator is generated by only four planar coils including two i…
Gradient-based optimization of 3D MHD equilibria
Elizabeth Paul, Matt Landreman, Thomas Antonsen
Using recently developed adjoint methods for computing the shape derivatives of functions that depend on MHD equilibria (Antonsen et al. 2019; Paul et al. 2020), we present the fir…
