Dataset for physics-informed field reconstruction and full-path energy-balance analysis of ion acceleration in vacuum arcs

This dataset supports the manuscript "Physics-informed field reconstruction and full-path energy-balance analysis identify a flux-weighted energy pathway for ion acceleration in vacuum arcs". The record contains numerical benchmark input data, PINN-reconstructed physical-field data, pointwise reconstruction-error data, summary error statistics, and energy-residual inversion outputs used for the full-path energy-balance analysis.
