摘要：

The enhancement of displacement damage energy deposition due to secondary neutrons, pions, deuterons, and alphas resulting from high-energy (100-1000 MeV) proton interactions with aluminum and tungsten shielding are examined in this paper. The results obtained using a comprehensive Monte Carlo charged particle transport code, MCNPX Version 2.1.5, indicated that the dominant secondary particle is neutrons. The additional contribution to the displacement damage energy produced by secondary pious, deuterons, and alphas turned out to be less than 5%.
