Minimum Quench Energy Characteristic of YBCO Coated Conductor With Different Stabilizer Thickness

The study on the minimum quench energy of YBCO coated conductor (CC) samples with different copper stabilizer thicknesses at various operating temperatures is performed. In this paper, we analyzed the thermal properties of YBCO CC in the adiabatic condition. Also, we measured the minimum quench energy of the three kinds of YBCO CC samples with different copper stabilizer thicknesses fabricated by Superpower Incorporated at various temperatures and currents. The results through this research will be utilized to determine the operating current of the conduction-cooled HTS magnet and to design the external protection circuit to keep the HTS magnet from being damage by a thermal quench.
