Interpretation of time-dependent current and resistance of HTS closed loop with superconducting joint considering flux creep
MDR Open Deposited
A low circuit resistance is required for a superconducting magnet operated in persistent mode using superconducting joints. We performed current decay measurements on a high-temperature superconducting (HTS) closed loop with a superconducting joint to evaluate the time dependence of current and resistance. The results were quantitatively explained considering current sharing and flux creep. After the elapse of 10^5 s, current sharing was suppressed and a circuit resistance of less than 10^−13 Ω was observed. The main finding is that joint resistance for an HTS closed loop is inversely proportional to time, contributing to the low circuit resistance.
