Y-Ba-Cu-O superconductor containing radioactive dopants

摘要

A polycrystalline Y-Ba-Cu-O superconductor doped with sufficient .sup. 235 U and/or .sup.239 Pu atoms is irradiated with thermal neutrons to produce from about 2.5×10.sup.14 to about 50×10.sup.14 fission events per cubic centimeter of superconductor.
