摘　　要：本文给出了一种用高温超导体制作的微型磁通泵,对其工作原理进行了仔细分析研究.依照设计研制了磁通泵装置,并对其工作性能进行了初步测试.结果表明,该微型高温超导磁通泵有希望为电阻在1μΩ以内的高温超导闭合环路进行供电.切实克服高温超导接头性能不佳、n指数低等缺陷,有助于Bi系等高温超导带材在超导磁体闭环系统的应用.This paper presents a kind of minitype high temperature superconducting（HTS） magnetic flux pump,its basic operation principle is described and studied in detail.According to the design,the setup has been developed and the working performance has been tested for the minitype HTS flux pump.The experimental result shows it is expected to supply power for the HTS closed loop which resistance is within 1μΩ.Using this minitype HTS flux pump may solve some problems such as joint resistance and low n-index in HTS closed loop systems.The new developed flux pump would help to the application of Bi series or other high temperature superconducting tapes in superconducting magnet closed loop systems.
