Abstract: Various commercial coated conductors were irradiated with fast neutrons inorder to introduce randomly distributed, uncorrelated defects which increasethe critical current density, Jc, in a wide temperature and field range. TheJc-anisotropy is significantly reduced and the angular dependence of Jc doesnot obey the anisotropic scaling approach. These defects enhance theirreversibility line in not fully optimized tapes, but they do not instate-of-the-art conductors. Neutron irradiation provides a clear distinctionbetween the low field region, where Jc is limited by the grain boundaries, andthe high field region, where depinning leads to dissipation.
