摘要：

The transport critical current density Jc of oxide-powder-in-tube mono- and multifilamentary Bi-2223/Ag tapes has been determined before and after irradiation by 0.8 GeV protons at fluences up to 7.0×1016 protons/cm2. Proton-induced fission of the Bi nuclei produced up to 8.6×1013 fissions/cm3, creating long tracks at densities equivalent to matching fields up to 1.1 T. Relative to unirradiated tapes, Jc values at 75 and 64 K show no decrease in self field, indicating no breakdown of intergranular coupling, and show large, dose-dependent enhancements in magnetic fields oriented parallel to the tape normal.© 1995 American Institute of Physics.
