Research Abstract

Neutron irradiation tests on Nb3Sn strands were carried out in a fission reactor and the magnetization and the critical temperatures were measured to discuss the effect of irradiation on the superconductivity. When the irradiation of 10^<22> n/m2 (> 0.1 MeV) was done, the critical current increased. But the irradiation of 10^<24> n/m2 damaged the strand and it did not show the superconductivity. The irradiation would strengthen the pinning force resulting in increasing the critical current.
