• PLD (pulsed laser deposition) prepared YBCO tapes were irradiated by 450MeV Xe23+ or 500MeV Au31+ ions with irradiation fluence from 1.0×1010 to 1.0×1012ions/cm2 to investigate for the effective condition which enhances Jc. As a result of ion-irradiation, we observed the enhancement of Jc especially at high applied magnetic field in 77K. It was also shown that Tc decreased with irradiation fluence. These changes of superconductive properties were found to depend on the kind of the ion and the energy. We also studied post-annealing effect on the irradiated tapes. After the ion-irradiation, the samples were annealed at the temperature of 473K or 673K in the oxygen atmosphere for 2h and then quenched. From the post-annealing experiments, we concluded that the post-annealing was a good way to recover Tc without decreasing Jc.
