Resumo
Systematic studies of 2G HTS wires irradiated by high-energy 167 MeV Xe ions and fluences up to 1·1012 cm−2 have been carried out. The optimal fluence value (the number of particles passing through 1 cm2 of the sample surface) for obtaining the maximum critical current at different temperatures and external magnetic fields has been determined. An increase in the external magnetic field leads to a shift of the critical current peak towards higher fluences in the whole temperature range. The results of microstructural investigations by transmission electron microscopy and X-ray diffraction methods are given. It is shown that because of irradiation ion tracks with a diameter of about 5-8 nm are formed, acting as effective pinning centers. X-ray diffraction analysis indicates a decrease in texture sharpness under the influence of irradiation.
