Development and large volume production of extremely high current density YBa₂Cu₃O₇ superconducting wires for fusion.

ABSTRACT: The fusion power density produced in a tokamak is proportional to its magnetic field strength to the fourth power. Second-generation high temperature superconductor (2G HTS) wires demonstrate remarkable engineering current density (averaged over the full wire), J_E, at very high magnetic fields, driving progress in fusion and other applications. The key challenge for HTS wires has been to offer an acceptable combination of high and consistent superconducting performance in high magnetic fields, high volume supply, and low price. Here we report a very high and reproducible J_E in practical HTS wires based on a simple YBa₂Cu₃O₇ (YBCO) superconductor formulation with Y₂O₃ nanoparticles, which have been delivered in jus
