Abstract

A high temperature superconducting (HTS) magnet for 10 kJ superconducting magnetic energy storage (SMES) system is designed by an improved optimal algorithm and cooled through GM cryocooler. In order to demonstrate the technology, a model HTS magnet made of Bi-2223/Ag tape to fabricate double-pancakes with the inner and outer diameters of 120 mm, 207.1 mm and height of 119 mm was fabricated and tested. The magnet is operating with GM cryocooler at 10 K. We have tested the Bi2223 HTS magnet at various ramping rates with 0.1-5.06 A/s. The experimental results show that the model HTS magnet is operating very stable. In the paper, we report the design of the HTS-SMES and fabrication technique for the model HTS magnet
