A Surrogate Model for Proton Spectrum Prediction to Map Transitions in Laser-Ion Acceleration
A decoupled dual-branch surrogate model predicts proton spectra with R²=0.94 for cutoff energy and flux, median spectral R²=0.985, and reproduces TNSA-to-RIT/BOA regime transitions validated on 1D PIC simulations.
