Pellet-Size Scaling of Quasi-Steady-State Plasma Performance in Wendelstein 7-X
Keisuke Fujii, Edgardo Villalobos Granados, Maryam Huck +11
A continuous cryogenic-pellet injector has been used to realize long-pulse high-performance plasmas in Wendelstein 7-X (W7-X). A hydrogen ice pellet deposits particles directly in…
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…
Validation of a Comprehensive First-Principles-Based Framework for Predicting the Performance of Future Stellarators
D. L. C. Agapito Fernando, A. Bañón Navarro, D. Carralero +20
This paper presents the validation of the framework for recovering both the steady-state plasma profiles in the considered radial domain and selected t…
First experimental observation of zonal flows in the optimized stellarator Wendelstein 7-X
D. Carralero, T. Estrada, J. M. García-Regaña +10
In this work, we present the first experimental evidence of the presence of zonal flow (ZF) structures in the optimized stellarator Wendelstein 7-X. Using an assortment of diagnost…
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…
Accelerated Bayesian inference of plasma profiles with self-consistent MHD equilibria at W7-X via neural networks
Andrea Merlo, Andrea Pavone, Daniel Böckenhoff +10
High- operations require a fast and robust inference of plasma parameters with a self-consistent MHD equilibrium. Precalculated MHD equilibria are usually employe…
