摘　　要：在成功建成世界首个全超导托卡马克装置EAST及加入ITER项目的基础上,我国正在进行聚变工程实验堆CFETR的设计工作。超导磁体作为CFETR主机系统重要的组成部分,其研制过程需要大电流、强磁场超导导体测试装置。文中详细介绍了超导导体测试平台的背场磁体系统,设计并研制了2kA二元高温超导电流引线、超导磁体失超探测及保护系统、低温系统,并开展了磁体降温及通电实验。With the experience of successful construction of the world＇s first all -superconducting Tokamak （EAST） and participation in the ITER project, China Fusion Engineering Test Reactor （CFETR） is now under design. The superconducting magnet is an important part of CFETR, a comprehensive superconducting test facility which will operate with high current and can supply high background magnetic field is required during its development process. This paper introduced the background magnet system of superconducting conductor test facility in detail. A pair of 2kA binary high - temperature superconducting current leader, quench detection and protection system, cryogenic system were also designed and used. The cooling of magnet and electrify test were then carried out.
