Abstract

A series of thermal superconducting switches for the superconducting magnet systems in the persistent mode have been developed at the Institute of Electrical Engineering, Academia Sinica. The maximum current is up to 300 A (at IT). The multifilament NbTi wire and cable with CuNi matrix and the multifilament Nb3Sn wire with bronze matrix are used for the superconducting switches respectively. Two types of NbTi superconducting switch have been made and operated in different superconducting magnet systems successfully. The researches on the closed process of the superconducting switch and some problems in the process have been engaged. The development of the thermal superconducting switch and the experimental results have been presented in this paper.
