The topology of non-resonant stellarator divertors

Nuclear Fusion
We apply topological methods to better understand how the magnetic field in the stellarator edge can be diverted away from the confined region. Our primary method is calculating the winding numbers of closed contours, which gives information on the ...

Stellar magnetism

Stellar Magnetism affects all spectral types and exists and varies throughout the evolution of stars. Magnetic fields can affect not only the interior of stars, but also their circumstellar environments. In this chapter, we concentrate on the magnetic fields that can be measured at the surface of stars through the influence of the Zeeman effect on ...

Direct construction of low-aspect-ratio advanced stellarators via asymptotic expansion

Nuclear Fusion
Advanced stellarators are promising candidates for fusion reactors due to their intrinsic steady-state operation capability and excellent plasma confinement properties.

Island divertor configuration design for a quasi-axisymmetric stellarator CFQS [PDF]

0000-0002-8156-8233A magnetic field configuration of an island divertor for a quasi-axisymmetric stellarator (CFQS) is proposed. The configuration incorporates large islands surrounding the core confinement region.

Stellarator fusion systems enabled by arrays of planar coils

Nuclear Fusion
We present an overview of a novel electromagnetic coil configuration for stellarators and its application to two near-term fusion systems. The novel coil configuration is the planar coil stellarator, able to implement precisely-quasisymmetric 3D magnetic

Trapped electron mode in a quasi-isodynamic stellarator

Nuclear Fusion
Global gyrokinetic simulations find a strongly unstable trapped electron mode excited by a density gradient in a quasi-isodynamic stellarator. The eigenmode structure localizes on the inner side of the torus with an unfavorable magnetic curvature and ...
