Recently, we have developed a calculation method of the displacement cross-sections in the energy range from 10 $^{-10}$ MeV to 3 GeV, including event generator and Coulomb scattering in the Particle and Heavy Ion Transport code System (PHITS). Including the defect production efficiencies as a function of the damage energy, calculated results for low-energy neutron and proton irradiation on copper and 1.1 and 1.94 GeV protons on copper gave good agreements with experimental data. As a results of application of J-PARC ADS target test facility (TEF-T) at a beam window and a irradiation specimen, the contribution of protons to DPA values is higher than that of neutrons by a factor of about three.
