Low-temperature neutron irradiation effects on superconducting Y-Ba-Cu oxides

Abstract

The results of in-pile measurements of low-temperature neutron irradiation (20 K, fast neutron dose 5.9×${10}^{16}$ n/${\mathrm{cm}}^2$) for two different high-$T_c$ Y-Ba-Cu oxide superconductors are reported. A broadening of the 60- and 90-K superconducting transitions and a drastic increase in resistivity near 200 K are observed.
