Abstract
One of the most promising power applications of high - Tc superconductors are Superconducting Magnetic Energy Storage (SMES) systems for storing and instantaneous discharging large quantities of power. The SMES system stores energy in the magnetic field generated by the flow of DC current in a coil of superconducting material that has been cryogenically cooled. This paper describes design of a 7.3 kJ conduction - cooled, high - Tc superconducting (HTS) magnet for experimental SMES system. This magnet consists of 14 single pancake - coils wound with Bi-2223 High Strength Wire with critical current of 115 A at 77 K. The operating current of the magnet is 135 A at 35 K. The described magnet is cooled in high vacuum cryostat using two-stage G-M cryocooler SRDK-408.
