Suppression of tearing modes by External Rotational Transform in a Tokamak-Stellarator hybrid configuration on J-TEXT

Nuclear Fusion
A Tokamak-Stellarator hybrid configuration has been established on the J-TEXT tokamak by the application of stellarator-like External Rotational Transform (ERT) coils.

Stellar Chromospheres [PDF]

International Astronomical Union Colloquium, 1980
Important progress in our understanding of stellar chromospheres has occurred in the past few years as a result of new observations, developments in spectral line formation theory, and the application of that theory to the construction of detailed model chromospheres.

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 ...

Stellarator Coil Design and Plasma Sensitivity [PDF]

, 2010
The rich information contained in the plasma response to external magnetic perturbations can be used to help design stellarator coils more effectively. We demonstrate the feasibility by first devel- oping a simple, direct method to study perturbations in

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 ...

ParaStell: parametric modeling and neutronics support for stellarator fusion power plants

Frontiers in Nuclear Engineering
The three-dimensional variation inherent to stellarator geometries and fusion sources motivates three-dimensional modeling to obtain accurate results from computational modeling in support of design and analysis of first wall, blanket, and shield (FWBS ...
