A framework for discrete optimization of stellarator coils
KC Hammond - ar** stellarator magnetic fields
We consider the novel problem of optimizing a large set of passive superconducting coils
(PSCs) with currents induced by a background magnetic field rather than power supplies. In …

[HTML][HTML] Use of current-potential patches to obtain fundamental improvements to the coils of magnetic fusion devices
AH Boozer - Physics of Plasmas, 2024 - pubs.aip.org
A central issue in the design of tokamaks or stellarators is the coils that produce the external
magnetic fields. The freedom that remains unstudied in the design of coils is enormous. This …
