2026-05-06 Monte Carlo simulation dataset for HRG-MCO optimization of moderator-collimator design in accelerator-based thermal neutron radiography doi:10.57760/sciencedb.j00186.00941 en The data contain Monte Carlo models, HRG-MCO optimization codes, and original figure data for the moderator-collimator design of an accelerator-based thermal neutron radiography system. The models include different structural parameters, source neutron energies, and neutron multiplier materials, while the optimization process involves LHS sampling, response surface modeling, genetic algorithm optimization, and NSGA-II multi-objective optimization.Neutron transport and optimization studies were conducted based on this dataset, including moderation efficiency optimization, multiplier material comparison, and thermal-neutron-induced photon yield ratio optimization. The results support the reproduction of the main conclusions of the paper and demonstrate the correctness and feasibility of the HRG-MCO optimization method.
