An Advanced Metal Organic Chemical Vapor Deposition (A-MOCVD) process has been developed to fabricate REBCO tapes with critical currents over 6200 A/12 mm (engineering current density (Je) = 5200 A/mm^2) at 4.2 K, 15 T which is 7X the Je of commercial REBCO tapes and 5.4X the Je of best Nb3Sn tapes. Such high performance is due to the excellent growth of 4 – 5 µm REBCO thick films and embedded...
High magnetic field studies are essential to understand high temperature superconductors. Because of their immense characteristic fields (>100 T) that cannot be reached using conventional DC magnets, measurements in pulsed fields are essential. The advent of hydrogen-based superconductors with critical temperatures in excess of 260 K heightens the need created by Cu- and Fe-based...
Conductor manufacturers worldwide are now making ReBCO coated conductors with optimized $J_c$ performance for applications at low temperatures and at ultra-high fields > 25T. There are several approaches to improve the whole conductor $J_e$ of ReBCO conductors: artificial pinning centers (APC), increased ReBCO thickness, and thinner substrates are three such thrusts being actively studied....
