The 1 MW HTS induction heater has developed for the non-ferrous metal industry where the HTS coil is used to generate a static magnetic field. The HTS magnet is made of YBCO conductor produced by Shanghai Superconductor, and the prospected operating temperature is about 25 K. The conduction-cooled HTS magnet consists of three solenoid coils wound with 18 km YBCO conductor. The inner and outer diameters of the YBCO magnet are Φ1960mm and Φ2009mm, respectively. The magnet system is cooled by two AL325 cryorefrigerators. According to the testing results at rated operation current of 130 A, the temperature of the HTS coils and the thermal shield are less than 20 K and 70 K, respectively, while are much better than the expected value.
