Particle irradiation is used to induce defects in high-temperature superconducting Y1Ba2Cu3O7-x (YBCO) coated conductors, containing predominantly c-axis oriented barium zirconate (BZO) nanorods as pre-existing vortex pinning defects. Samples are irradiated with 50.0 MeV Cu ions with doses of 2.5 x 1012, 2.0 x 1012, 1.5 x 1012, 1.0 x 1012, 0.75 x 1012, 0.5 x 1012, 0.05 x 1012 ions/cm2. The dose of 0.5 x 1012 ions/cm2 is found to be the optimal dose with a …
