A new facility for investigation on neutron irradiation effect on superconducting properties of Nb3Sn strand for fusion magnet

► A new test facility for measuring the superconducting properties was introduced in a radiation control area. ► The maximum magnetic field of 15.5 T can be supplied and the maximum current to a sample is 500 A. ► A SQUID system up to 7 T is also available in the radiation control area at Oarai center. ► 500 A was successfully put in Nb3Sn strand under 15.5 T and the magnetization of the irradiated samples was measured.
