Non-Confidential Brief
Segmented Planar Stellarator Coils
Princeton Docket # 25-4189-1
Researchers at the Princeton Plasma Physics Laboratory propose a novel configuration of stellarator fusion reactor coils. Traditional stellarator coils incorporate a complex, non-planar design in order to magnetically confine the plasma in a specified equilibrium. This leads to numerous engineering challenges in a complex manufacturing process. The inventors describe a previously unexplored coil configuration of two planar curves joined at break points. The simpler geometry of these coils presents a more straightforward engineering process while producing comparable performance in plasma equilibrium.
Applications
- Magnetic confinement of plasma in a stellarator fusion reactor
Advantages
- Simplified and less expensive coil engineering process
