Design study of conduction-cooled high temperature superconducting magnet

Publisher Summary This chapter presents design and fabricating technique of a separator using the conduction-cooled high temperature superconducting (HTS) magnet for a National High-technology Program in China. The magnet is made of Bi-2223 double pancake coils, and has inner and outer coil diameters of 120 mm and 211.2 mm respectively and coil height of 202.8 mm. The superconducting magnet includes 20 double pancake coils. The operating current is about 87.8 A. This magnet is cryocooler-cooled with no liquid helium and should generate a magnetic filed of 3 T at a temperature of 20 K. The HTS magnetic separators have a variety of industrial applications, most notably in the pharmaceutical, environmental, chemical fields, and treatment for waste water in steel industry. The conceptual design and fabrication details of a conduction-cooled HTS Reciprocating Magnetic Separator are reported. Reciprocating magnetic separators are used in waste water treatment for special steel factory. The salient features and results of the electromagnetic, thermal, and quench protection analyses have been discussed.
