Machine-learning surrogate models for nonlinear energetic-particle transport predictions in ITER
Yashika Ghai, Donald A. Spong, Jacobo Varela +1
Fast and accurate prediction of energetic-particle transport driven by Alfvén eigenmode (AE) instabilities is essential for integrated modeling workflows used in the design and opt…
Theoretical analysis of energetic-ion-driven resistive interchange mode stabilization strategies using a Landau closure model
J. Varela, S. Ohdachi, K. Y. Watanabe +3
The aim of the present study is to perform a theoretical analysis of different strategies to stabilize energetic-ion-driven resistive interchange mode (EIC) in LHD plasma. We use a…
Modeling of the ECCD injection effect on the Heliotron J and LHD plasma stability
J. Varela, K. Nagasaki, K. Nagaoka +6
The aim of the study is to analyze the stability of the Energetic Particle Modes (EPM) and Alfven Eigenmodes (AE) in Helitron J and LHD plasma if the electron cyclotron current dri…
Parametric study and optimization trends for the Von-Kármán-Sodium dynamo experiment
J. Varela
We present magneto-hydrodynamic simulations of liquid sodium flow with the PLUTO compressible MHD code. We investigate the influence of the remnant magnetic field orientation and i…
