Abstract

The quench current characteristics of the superconducting solenoids with large diameter were experimentally investigated. Three solenoids with the inside diameter of 450mm were fabricated and tested for various winding tensions and epoxy impregnation conditions. The highest quench current was obtained in the solenoid impregnated with epoxy after wound with winding tension of 20 percents. Although the training effect in the solenoid appeared after epoxy impregnation, The quench current of solenoid impregnated with epoxy was higher than that before impregnation. The test results and discussions were presented.
