Abstract
- The new series of commercially produced high temperature superconducting (HTS) tapes based on the YBa 2 Cu 3 O 7 (YBCO) structure have attracted renewed attention for their performance under applied magnetic fields without significant loss in supercurrent compared to the earlier generation of conductors. This adaptability is achieved through rare earth substitution and dopants resulting in the formation of nanoparticles and extended defects within the superconducting film matrix. The electrical performance of Zr-(Gd x ,Y 1 − x )Ba 2 Cu 3 O 7 and (Y 1 − x ,Dy x )Ba 2 Cu 3 O 7 coated conductor tapes were tested prior to and after neutron exposures between 6.54 × 10 17 and 7.00 × 10 18 n/cm 2 ( E > 0.1 MeV). Results showed a decrease in superconducting current with neutron irradiation for the range of fluences tested, with losses in the Zr-(Gd x ,Y 1 − x )Ba 2 Cu 3 O 7 conductor being more rapid. Post-irradiation testing was limited to evaluation at 77 K and applied fields of up to 0.5 Tesla, and therefore testing at lower temperatures and higher applied fields may result in improved superconducting properties as shown in previous ion irradiation work. Under the conditions tested, the doped conductors showed a loss in critical current at fluences lower than that of undoped YBa 2 Cu 3 O 7 tapes reported on in literature.
