For the high-energy proton incident reactions, a target PKA created by the secondary particles was more dominant than a target PKA created by the projectile. To validate prediction of DPA values in metals irradiated by >100 MeV protons, we developed a proton irradiation device with a Gifford-McMahon (GM) cryocooler to cryogenically cool wire samples. By using this device, the defect-induced electrical resistivity changes related to the DPA cross section of copper and aluminum were measured under irradiation with 125 and 200 MeV protons at cryogenic temperature. A comparison of the experimental DPA cross sections with the calculated results indicates that the athermal-recombination-corrected displacement damage (arc-dpa) provide better quantitative descriptions of the DPA cross section than NRT-dpa without defect production efficiencies.
