2026-09-14 Data and analysis code for "Effect of Sparse-Angle Neutron Tomography Reconstruction on Local Elemental Quantification by Prompt Gamma Activation Imaging" doi:10.57760/sciencedb.j00186.000zd en This dataset supports the study "Effect of Sparse-Angle Neutron Tomography Reconstruction on Local Elemental Quantification by Prompt Gamma Activation Imaging". It contains 48-view neutron attenuation projections, three-dimensional attenuation fields reconstructed with eleven NT configurations, and binned PGAI spectra and response matrices at y = -8, 0, and 8 mm. The files also include energy-dependent response corrections, source tables for six figures, model parameters, and Python analysis code. The supplied inputs support recalculation of the spectral fits, composition errors, bootstrap comparisons, and held-out reprojection results. The acquisition was simulated in Geant4 for an Fe/Ni/Cu gradient cylinder; the deposited measurements are processed simulation data. Event-level tracking logs and unrelated project files are not included.
