Multi Solenoid Type Magnet for 1 MJ HTS SMES System

Abstract

Recently the superconducting technology was more and more mature. The development of the technology allows us to apply superconducting magnetic energy storage (SMES) system to our life. An increasing number of scientists and engineers participate in study of SMES system. The application prospect of SMES system is very extensive, however, the leakage magnetic field limits application of SMES system. In this paper, multi solenoid type magnet, an improved structural for the 1 MJ single-solenoid structure magnet, is designed by using the actively shielding theory. The multi solenoid type magnet has potential to reduce the leakage magnetic field.
