Abstract

We are carrying out a National High Technology Program in China to fabricate a magnetic separator by using a conduction-cooled Bi-based high temperature superconducting (HTS) magnet. The magnet is made of Bi-2223 pancakes, and has the inner and outer coil diameters of 120 mm and 211.2 mm and coil height of 202.8 mm. The operating current is about 80 A. This magnet is cryocooler-cooled with no liquid helium and should generate a magnetic field of 3 T at a temperature of 20 K. In the paper, we report the design and fabrication technique of the HTS magnet.
