Finite-β turbulence in Wendelstein 7-X enhanced by sub-threshold kinetic ballooning modes

Nuclear Fusion
Magnetic fluctuations affecting turbulence and transport, which are manifest at finite normalized plasma pressure β , pose a significant challenge to magnetic confinement fusion devices aiming to achieve high performance.

Particle transport in reduced turbulence neutral beam heated discharges at Wendelstein 7-X

Nuclear Fusion
A spontaneous reduction in anomalous particle transport in the plasma core is seen experimentally in reproducible, purely neutral beam heated plasma phases at Wendelstein 7-X (W7-X).

Neural network-based surrogate model for 3D edge-plasma transport in the standard configuration of W7-X

Nuclear Fusion
This paper presents a neural‐network surrogate model for Wendelstein 7-X (W7-X) edge transport simulations, trained on an EMC3-EIRENE dataset that spans nearly the entire operating-parameter space currently explored in the W7-X standard configuration ...

Investigating the role of divertor geometry on density build-up in the island divertor

Nuclear Materials and Energy
The island divertor has been proposed for power and particle exhaust in stellarators. It is investigated in the Wendelstein 7-X (W7-X) experiment. The divertor capabilities such as particle exhaust or radiative power dissipation scale with the divertor ...

Microwave diagnostic at Wendelstein 7-X

At Wendelstein 7-X (W7-X), the world's largest superconducting stellarator with a five-fold symmetry and reduced neoclassical transport, a broad suite of microwave diagnostics is installed and operated. Due to the robustness of in-vessel components and transmission lines against the harsh environment in fusion devices, they are candidates for reactor ...
