A large-scale superconducting magnet cryogenic performance research platform is being built in China to perform the large-scale superconducting magnet research on mechanics, thermology and electromagnetics properties and evaluate the superconducting magnet system compatibility, reliability and stability. Performance research platform has an oversized test space whose dimension is 24 m × 15 m × 6.5 m, including a pair of the high temperature superconducting current lead with current carrying capacity of 100 kA. Cryogenic system of the performance research platform can provide the supercritical helium of mass-flow about 700 g/s at 3--6 bars. The detection accuracy of the quench detection and protection system can reach 99.99%. Performance research platform will be utilized for superconducting magnet tests, such as DC hipot test, helium leakage, Paschen test, maximum operation current test, joint resistance, Tcs test and Fast discharge test.
