초록

The quench current characteristics of the superconducting solenoids with large diameter were experimentally investigated. Three solenoids with inside diameter of 450mm were fabricated with different tensions and different types of epoxy applications. The quench current of each solenoid was measured according to the various ramping rates of current. The highest quench current was obtained in the solenoid impregnated with epoxy after winding with tension of 20 percents of the yield strength of the superconducting wire. It was found that the quench currents were almost independent of the ramp rate of current. From the results, although the training effect in the solenoid appeared with epoxy impregnation, the quench current of solenoid impregnated with epoxy was higher than that without epoxy impregnated The test results are presented and discussed.
