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 f...
