Physics Attention Transformer Surrogate for Rapid Vertical Instability Growth Rate Prediction: Alcator C-Mod to SPARC
Arunav Kumar, Cesar Clauser, Theodore Golfinopoulos +5
In this work, we investigate rapid prediction of the dominant vertical instability growth rate in C-Mod and SPARC equilibria, where nonrigid free boundary response models a…

On the feasibility of model-based feedback control of vertical instability growth rate using out-vessel coils in ARC-like scenarios
Arunav Kumar, Cesar Clauser, Theodore Golfinopoulos +1
In this work, we propose a model-based feedback controller that regulates the vertical instability growth rate () of a high-elongation, double-null tokamak directly, using…

Feasibility of Negative Triangularity Equilibria in the SPARC Tokamak
Narin Yüksek, Theodore Golfinopoulos
We investigate the feasibility of negative triangularity (NT) plasma configurations in the SPARC tokamak, a compact, high-field device (up to 12.2 T) designed for positive triangul…
