Neural network predictions of plasma confinement loss in Wendelstein 7-X pellet-fueled discharges
K. C. Hammond, J. -P. Bähner, J. Baldzuhn +17
The energy confinement time is a key parameter of a magnetized fusion plasma, helping to determine whether ignition can occur. Experiments in tokamaks and stellarators have shown t…
Microtearing Turbulence and Its Role in High-Density-Gradient Plasmas in Wendelstein 7-X
H. Cu-Castillo, A. Bañón Navarro, G. Merlo +10
Gyrokinetic simulations reveal that microtearing mode (MTM) turbulence dominates transport in a Wendelstein 7-X (W7-X) discharge characterized by large density gradients, moderate…
The Realization of a Gas Puff Imaging System on the Wendelstein 7-X Stellarator
J. L. Terry, A. von Stechow, S. G. Baek +10
A system for studying the spatio-temporal dynamics of fluctuations in the boundary of the W7-X plasma using the Gas-Puff Imaging (GPI) technique has been designed, constructed, ins…
Global gyrokinetic analysis of Wendelstein 7-X discharge: unveiling the importance of trapped-electron-mode and electron-temperature-gradient turbulence
Felix Wilms, Alejandro Bañón Navarro, Thomas Windisch +8
We present the first nonlinear, gyrokinetic, radially global simulation of a discharge of the Wendelstein 7-X-like stellarator (W7-X), including kinetic electrons, an equilibrium r…
Observation of a drift-driven local transport regime in the island divertor of Wendelstein 7-X
E Flom, D M Kriete, M Krychowiak +9
Measurements of the poloidal electron density and temperature distribution in the W7-X island divertor reveal the existence of two distinct scrape-off layer transport regimes. At l…
Suppression of core turbulence by profile shaping in Wendelstein 7-X
A. v. Stechow, O. Grulke, Th. Wegner +23
In the Wendelstein 7-X magnetic confinement experiment, a reduction of turbulent density fluctuations as well as anomalous impurity diffusion is associated with a peaking of the pl…
First Results from an Event Synchronized -- High Repetition Thomson Scattering System at Wendelstein 7-X
Hannes Damm, Ekkehard Pasch, Andreas Dinklage +16
The Wendelstein 7-X (W7-X) Thomson scattering (TS) diagnostic was upgraded to transiently achieve kilohertz sampling rates combined with adjustable measuring times. The existing Nd…
