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…
Hot Spot Evolution Measured by High-Resolution X-Ray Spectroscopy at the National Ignition Facility
Lan Gao, B. F. Kraus, K. W. Hill +19
Evolution of the hot spot plasma conditions was measured using high-resolution x-ray spectroscopy at the National Ignition Facility (NIF). The capsules were filled with DD gas with…
Radial electric field and density fluctuations measured by Doppler reflectometry during the post-pellet enhanced confinement phase in W7-X
T. Estrada, D. Carralero, T. Windisch +13
Radial profiles of density fluctuations and radial electric field, , have been measured using Doppler reflectometry during the post-pellet enhanced confinement phase achieved,…
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…
Observation and characterisation of trapped electron modes in Wendelstein 7-X
A. Krämer-Flecken, J. H. E. Proll, G. Weir +17
In the past, quasi coherent modes were reported for nearly all tokamaks. The general definition describes modes as quasi coherent when the magnitude squared coherence is in the ran…
Direct optimization of neoclassical ion transport in stellarator reactors
B. F. Lee, S. A. Lazerson, H. M. Smith +2
We directly optimize stellarator neoclassical ion transport while holding neoclassical electron transport at a moderate level, creating a scenario favorable for impurity expulsion…
