For defect production, it is the number of recoils weighted by the damage energy produced in each recoil that is most important. This quantity is determined by "weighed" the recoil spectra by the damage energy produced in each recoil. However, the damage energy spectra have not been investigated yet for the proton energy range from several MeV to hundred GeV, where recoil is regarded as nuclear reaction product. In this work, we calculated damage energy spectra of all nuclear reaction products under high energy proton irradiation on tungsten with the energy range from 10 MeV to 120 GeV using the PHITS code. The average damage energy of tungsten was 30-80 keV including nuclear elastic and non-elastic components and that of lutetium was 550-900 keV including non-elastic component. In this presentation, we will also introduce our experimental plan for measurement of dpa cross sections with 120 GeV protons at Fermi National Accelerator Laboratory (FNAL).
