Resistance and Voltage–Current Characteristics of REBCO Superconducting Joint

Year: 2025

Type: article

Abstract: We discuss resistance and voltage–current characteristics of a REBa2Cu3Oy(REBCO, RE = rare earth) intermediate grown superconducting (iGS) joint. These characteristics are evaluated based on the current decay measurements for a REBCO closed loop. The temperature and magnetic field dependencies of thenvalue for the iGS joint, assessed using an empirical power-law model, are similar to those observed for REBCO tapes. The percolation model describes the voltage–current characteristics of the iGS joint more accurately. Using the critical current andnvalues at 10−8V, we can approximately estimate the upper limit of the current for a low target resistance.
