Gyrokinetic prediction of core tungsten peaking in a WEST plasma with nitrogen impurities

Nuclear Fusion
Tungsten peaking is predicted in the core of a WEST plasma with total-f gyrokinetic simulations, including both collisional and turbulent transport. This prediction is validated with a synthetic diagnostic of the bolometry.

Enhancing stellarator accessibility through port size optimization

Nuclear Fusion
Access to the plasma chamber in a stellarator reactor is essential for maintenance and diagnostics. However, the complex geometry of stellarator coils, often characterized by their strong twisting, can severely limit the space available for access ports.

Double-helix stellarator

, 1997
A new stellarator configuration, the Double-Helix Stellarator (DHS), is introduced. This novel configuration features a double-helix center post as the only helical element of the stellarator coil system.

A framework for discrete optimization of stellarator coils

Nuclear Fusion
Designing magnets for three-dimensional plasma confinement is a key task for advancing the stellarator as a fusion reactor concept. Stellarator magnets must produce an accurate field while leaving adequate room for other components and being reasonably ...

Impact of spatially varying transport coefficients in EMC3-Eirene simulations of W7-X and assessment of drifts

Nuclear Fusion
Modelling the scrape-off layer of a stellarator is challenging due to the complex magnetic 3D geometry. The here presented study analyses simulations of the scrape-off layer (SOL) of the stellarator Wendelstein 7-X (W7-X) using spatially varying ...
