摘要

The effects of 100 MeV electron (to 3.6×1018 cm-2) and fast neutron irradiation (to 4.0 × 1018 cm-2) on the superconducting properties of melt-textured YBa2Cu3O7-σ is studied experimentally. By comparing the critical current enhancement effects normalized to the total atomic displacement damage, it is found that the enhancement depends heavily on the type and energy of radiation and on the beam direction with respect to the crystal. Fast neutron irradiation is more effective than 100 MeV electron irradiation (along the c-axis) in enhancing the critical current, and electron irradiation along the c-axis is more effective than electron irradiation along the a, b-plane. A model based on defect size is proposed to interpret the effects.
