Study of the impact of fast ions on core turbulence at rational surfaces via global gyrokinetic simulations
D. Brioschi, A. Di Siena, R. Bilato +6
In this work, the interplay between fast ions and safety factor rational surfaces is studied in a turbulent plasma via global nonlinear gyrokinetic simulations. Initially, the fast…
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…
Radiative signatures of electron-ion shocks in BL Lac type objects
A. Arbet-Engels, A. Bohdan, F. Rieger +2
Shocks are promising sites of particle acceleration in extragalactic jets. In electron-ion shocks, electrons can be heated up to large Lorentz factors, making them an attractive sc…
Optimizing Particle Transport for Enhanced Confinement in Quasi-Isodynamic Stellarators
A. Bañón Navarro, A. Di Siena, F. Jenko +2
Despite significant advances in reducing turbulent heat losses, modern quasi-isodynamic (QI) stellarators -- such as Stellaris -- continue to suffer from poor particle confinement,…
Simulating X-point radiator turbulence
K. Eder, W. Zholobenko, A. Stegmeir +5
Coupling a high-performance burning plasma core to a detached boundary solution is critical for realizing magnetic confinement fusion power. Predictive simulations of the edge and…
Simulations of edge and SOL turbulence in diverted negative and positive triangularity plasmas
P. Ulbl, A. Stegmeir, D. Told +3
Optimizing the performance of magnetic confinement fusion devices is critical to achieving an attractive fusion reactor design. Negative triangularity (NT) scenarios have been show…
