Topology optimization of permanent magnets for stellarators
Caoxiang Zhu, Kenneth Hammond, Thomas Brown +5
We introduce a topology optimization method to design permanent magnets for advanced stellarators. Recent researches show that permanent magnets have great potentials to simplify s…
Heat and particle flux detachment with stable plasma conditions in the Wendelstein 7-X stellarator fusion experiment
Marcin Jakubowski, Ralf König, Oliver Schmitz +30
Reduction of particle and heat fluxes to plasma facing components is critical to achieve stable conditions for both the plasma and the plasma material interface in magnetic confine…
Global scaling of the heat transport in fusion plasmas
Sara Moradi, Johan Anderson, Michele Romanelli +2
A global heat flux model based on a fractional derivative of plasma pressure is proposed for the heat transport in fusion plasmas. The degree of the fractional derivative of the he…
Large vacuum flux surfaces generated by tilted planar coils
Jessica L. Li, Jacob Austin, Ben Y. Israeli +2
Helical equilibria can be generated by arrangements of planar coils similar to tokamaks, but without a central solenoid and with the toroidal field (TF) coils tilted with respect t…
Overdense microwave plasma heating in the CNT stellarator
K. C. Hammond, R. R. Diaz-Pacheco, A. Koehn +2
Overdense plasmas have been attained with 2.45 GHz microwave heating in the low-field, low-aspect-ratio CNT stellarator. Densities higher than four times the ordinary (O) mode cuto…
High- equilibrium and ballooning stability of the low aspect ratio CNT stellarator
K. C. Hammond, S. A. Lazerson, F. A. Volpe
The existence and ballooning-stability of low aspect ratio stellarator equilibria is predicted for CNT with the aid of 3D numerical tools. In addition to having a low aspect ratio,…
