Outline of Final Research Achievements

The　measurement　method　of　radiation　damage　on　metals　under high-energy proton　irradiations　has been developed to validate the radiation damage model used for radiation damage estimation on materials in accelerator facilities. As results, we developed the small cryogenic irradiation device which is available in various accelerator facilities and measured resistivity increase with nano-ohm order under irradiations. The data has been reported in the IAEA's research activity on "Primary radiation damage cross sections".
