Abstract
The superconducting transition temperatureT c of a Nb3Sn diffusion wire has been studied as a function of low-temperature neutron irradiation (T=10 K).T c is observed to be essentially constant until the fast neutron dose φt (for neutron energiesE>0.1 MeV) exceeds a value of 1018 n/cm2; after this valueT c decreases linearly with φt up to the maximum applied dose of 1.05×1019 n/cm2. Comparison with theory and other experimental data indicates that radiation-induced disorder is the primary mechanism for the observedT c changes.
