Design and Performance Results of First Polish SMES

The magnet for superconducting magnetic energy storage system (SMES) cooled by SRDK-408 cryocooler has been described in this paper. The superconducting magnet consists of 7 double-pancake coils made of Bi-2223 HTS tape with the inner and outer diameters 210 mm, 315 mm respectively and height of 191 mm. The inductance of the magnet is about 1 H. In the paper we report the design and the first measurements results of the magnet.
