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 ...

Design and experimental verification of a multi-pass ECRH plasma start-up scenario at a reduced magnetic field of 1.8 T at W7-X

Nuclear Fusion
Wendelstein 7-X (W7-X) nominally operates at a magnetic field of 2.5 T, but operation at a lower magnetic field strength is desired. The electron cyclotron resonance heating (ECRH) system of W7-X operates at 140 GHz, corresponding to second harmonic (X2)

Microwave diagnostic at Wendelstein 7-X

Journal of Instrumentation
Abstract 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 ...

Characterizing core and edge turbulence regimes with fluctuation imaging diagnostics in Wendelstein 7-X

Nuclear Fusion
Two density fluctuation imaging systems, phase contrast imaging (PCI) and gas puff imaging (GPI) measure spatially resolved density fluctuations with high time resolution throughout the core plasma (PCI) and in the scrape-off layer (GPI) of the ...
