摘　　要：中国科学院电工研究所研制了一个磁流体发电用鞍型超导磁体．这个磁体的室温孔径为４４ｃｍ，有效磁长度为１０３ｃｍ，中心磁场为４Ｔ．它由１７展共３４个鞍型线圈组成．线圈所用ＮｂＴｉ超导线截面为２ｍｍ×１０ｍｍ，由Ｓｕｐｅｒｃｏｎ公司提供．本文将介绍磁体的性能与实验结果．实验表明该磁体能在中心磁场达４．１３Ｔ下稳定可靠地运行，完全满足设计和使用要求．Abstract A saddle superconducting magnet for experimental MHD generator was completed at Institute of Electrical Engineering, Academis Sinica. The magnet has Φ44cm warm bore, 103 cm effective magnetic length and 4 T central field. It consists of 17 layers, each layer has two circular saddle coils with 54. 5°segment cross section. The conductor is 2 mm×10 mm NbTi monolithic provided by Supercon Inc.. The performances and the tot results of the saddle superconducting magnet are presented in this paper. The test shows that the magnet ran steadily and reliably with central field of 4. 13 T. The saddle magnet meets perfectly the design and application requirements.
