Adjoint approach to calculating shape gradients for three-dimensional magnetic confinement equilibria. Part II: Applications
Elizabeth J. Paul, Thomas Antonsen, Matt Landreman +1
The shape gradient is a local sensitivity function that provides the change in a figure of merit associated with a perturbation to the shape of the object. The shape gradient can b…
Direct construction of optimized stellarator shapes. III. Omnigenity near the magnetic axis
G. G. Plunk, M. Landreman, P. Helander
The condition of omnigenity is investigated, and applied to the near-axis expansion of Garren and Boozer (1991a). Due in part to the particular analyticity requirements of the near…
Constructing stellarators with quasisymmetry to high order
Matt Landreman, Wrick Sengupta
A method is given to rapidly compute quasisymmetric stellarator magnetic fields for plasma confinement, without the need to call a three-dimensional magnetohydrodynamic equilibrium…
An adjoint method for neoclassical stellarator optimization
Elizabeth Paul, Ian Abel, Matt Landreman +1
Stellarators are a promising route to steady-state fusion power. However, to achieve the required confinement, the magnetic geometry must be highly optimized. This optimization req…
Optimized quasisymmetric stellarators are consistent with the Garren-Boozer construction
Matt Landreman
Most quasisymmetric stellarators to date have been designed by numerically optimizing the plasma boundary shape to minimize symmetry-breaking Fourier modes of the magnetic field st…
