Recent Development of Magnet Technology in China: Large Devices for Fusion and Other Applications

The projects for large science devices and industrial applications are strongly driving the progress of superconductivity and magnet technology in China. One example is the EAST Tokamak-the biggest superconductivity project in China. The magnet system of EAST consists of twenty-eight large superconducting coils. The technology of superconducting magnet for fusion device is well developed. At same time, three accelerator projects are funded: the HIRFL-CSR, a cooler storage ring for the Heavy Ion Research Facility has been built and its commissioning is starting; the BEPCII High Luminosity Double ring Collider and its superconducting BESIII detector magnet are in progress; The Shanghai Synchrotron Radiation Facility (SSRF) project is going on. The proposed high magnetic field laboratory project would bring along the magnet technology further. The R&D for prototype of power cable, transformer, fault current limiter and SMES show good possibility of application of HTS in the future. The recent development of magnet technology in China is introduced in this paper
