Description
Summary:The second generation (2G) HTS conductors, the YBaCuO Coated Conductors, show very exciting performances in terms of critical currents under very high fields whereas their mechanical properties, the key issues for very high field magnets, are outstanding for the IBAD (Ion Beam Assisted Deposition) route. Preliminary measurements have shown critical currents Ic above 500 A at 15 T and 4 K on commercial YBCO coated conductors. They are now available in reasonable length and manufacturing focus to provide reliable, consistent performance conductors. With these high critical current and tensile strength above 600 MPa, these conductors are very promising for making HTS superconducting coils able to generate very high field. But very few characterizations exist above 20 T. LNCMI is one of the few facilities in the world where such measurement can be performed.
