本文介绍了一种制冷机冷却的19 T超导磁体的设计。磁体的技术特点是由25个双饼线圈组成的Bi 2223插入线圈，使用Nb-Ti-Cu化合物增强的Nb/sub 3/Sn线的Nb/sub 3/Sn线圈，以及使用两种类型的低温冷却器的冷却结构。通过数值分析证实了线圈的淬火保护。为了研究弯曲应变对Ag护套Bi 2223带导体最大允许环向应力的影响，进行了初步的实验。
This paper describes a design of a cryocooler-cooled 19 T superconducting magnet. The technical features of the magnet are a Bi2223 insert coil composed of 25 double pancake coils, Nb/sub 3/Sn coils using a Nb/sub 3/Sn wire reinforced with Nb-Ti-Cu compound, and a cooling structure using two types of cryocoolers. Coil protection from quenching was confirmed by numerical analysis. A preliminary experiment was carried out in order to investigate the influence of the bending strain upon a maximum permissible hoop stress of Ag-sheathed Bi2223 tape conductor.
