Thermal stability analysis of second-generation high-temperature superconductor according to stabilizer thickness

This paper reports a study on stability characteristics of the ReBCO coated conductor (CC) sample with different copper stabilizer thicknesses which are fabricated by Superpower Company. This sample was cooled by Liquid Nitrogen (LN2) boiling at 77.3 K and an equivalent electrical circuit model for them was shown. To verify the stability characteristics of this tape, a DC transport current pulse of 90% the critical current and an over-current pulse test in which a current exceeding a critical current was performed. Based on the test results, the stability characteristics of this sample was evaluated and discussed.
