Description
The superconducting solenoid for the muon source to be installed in the future second target station of materials and life science experimental facility of J-PARC is required to be highly radiation resistant. Over a 10-year operation period, the superconducting solenoid is expected to reach an absorbed dose of 100 MGy and a neutron fluence of 7.8$\times10^{22}$ $n/m^{2}$. A research and development program have been performed radiation-resistant magnets based on REBCO conductors. Radiation resistance study of REBCO conductors is essential for realizing the radiation-resistant magnets. In this contribution, the post-irradiation examination of REBCO samples neutron irradiated in the Belgian research reactor (BR2) and the Japanese research reactor (JRR3) in the neutron flux range of 0.1-10$\times10^{22}$ $n/m^{2}$ will be presented.
