Generative Data-Augmented Surrogate Modelling Framework for Field Quality Improvement in ReBCO Bulk Undulators Under Limited Data Constraints
Abstract High-temperature superconducting (HTS) bulk staggered-array undulators can generate record-breaking magnetic fields for compact light sources, but their performance is limited by non-uniform magnetic field profiles. This spatial inhomogeneity is directly related to variations in the critical current density am...
