Abstract

The influence of fast neutron radiation on the transition temperature Tc, upper critical field Hc2, and structural peculiarities of Nb3Sn is investigated. For heavily irradiated samples (doses higher than 1 × 1019 cm−2) drastically reduced values for Tc, Hc2, and degree of long-range order are observed. The appearance of thermal neutron small-angle diffuse scattering and the sharp increase of the transition breadth in irradiated samples show the creation of disordered phase microregions during irradiation.
