Physics-augmented surrogate model for linear instability analysis of high- n toroidal Alfvén eigenmodes in tokamaks
We propose the physics-augmented surrogate model for linear instability analysis of high- n toroidal Alfvén eigenmodes (TAEs) in tokamaks. The database for high- n TAE linear instabilities is generated by the global initial-value simulations by Gyrokinetic magnetohydrodynamic Energetic-particle Code (GMEC), and also th...
