FOCUS-HTS: a new stellarator coil design code for three-dimensional high-temperature superconducting magnets

Nuclear Fusion
Stellarators mainly utilize magnetic fields from external coils to confine the plasma, enabling steady-state operation while avoiding instabilities like disruptions raised from plasma currents.

Stellar Flare Optimization Algorithm

Various physical phenomena in nature provide a wealth of heuristic inspiration for optimization algorithms. This paper proposes a new heuristic optimization algorithm based on the stellar flare phenomenon, the Stellar Flare Optimization Algorithm (SFOA). This algorithm achieves efficient search for complex optimization problems by simulating the sudden

Quasi-single-stage optimization for permanent magnet stellarators

Nuclear Fusion
Advanced stellarators are typically optimized in two stages. The plasma equilibrium is optimized first, followed by the design of coils/permanent magnets.

Data-driven approach to model the influence of magnetic geometry in the confinement of fusion devices

Nuclear Fusion
Designing a fusion energy device to produce as much energy as possible requires balancing numerous physics constraints and metrics. In stellarators, the geometry is very flexible and involves a large number of free parameters.
