A Pre-trained Variational Autoencoder for Gyrokinetic Plasma Turbulence Surrogate Modeling
Minglei Yang, Marshall Nicholson, Diego Del-Castillo-Negrete +2
Machine learning surrogate models offer a promising path toward accelerating plasma turbulence simulations. We present PreVAE-Turb, a surrogate modeling framework that leverages pr…
Runaway electron interactions with whistler waves in tokamak plasmas: energy-dependent transport scaling
Yashika Ghai, D. Del-Castillo-Negrete, D. A. Spong +1
Resonant interactions between high energy runaway electrons (REs) and whistler waves are a promising mechanism for RE mitigation in tokamak plasmas. While prior studies have largel…
Effect of the neutral beam injector operational regime on the Alfven eigenmode saturation phase in DIII-D plasma
J Varela, D A Spong, L Garcia +11
The aim of this study is to analyze the effect of the neutral beam injector (NBI) operation regime on the saturation phase of the Alfven Eigenmodes (AEs) in DIII-D plasma. The anal…
Off-axis runaway-electron seed formation, growth and suppression
L. F. Delgado-Aparicio, D. Del-Castillo-Negrete, N. C. Hurst +11
Novel x-ray detection technology enabled the first profile measurements of the birth and growth dynamics of runaway electrons (REs) at the edge of tokamaks during quiescent RE stud…
Spatially-dependent modeling and simulation of runaway electron mitigation in DIII-D
M. T. Beidler, D. del-Castillo-Negrete, L. R. Baylor +2
New simulations with the Kinetic Orbit Runaway electron (RE) Code KORC show RE deconfinement losses to the wall during plasma scrape off are the primary current dissipation mechani…
