研究了高温超导磁体的指数损耗的特征.数值仿真了在20K温度下由20个高温超导双饼线圈组成的超导磁体的指数损耗.分析了每个双饼及每匝线圈的指数损耗.研究了磁体的指数损耗随电流变化的趋势.通过在磁体两端增加铁轭改变磁体上的磁场,研究发现增加铁轭可以有效的减少磁体上产生的指数损耗.

An analysis of the characteristic on index loss of high-temperature superconducting (HTS) magnet was carried out.The index loss of a HTS magnet including 20 double- pancake coils at 20 K was analyzed using numerical simulation.The index loss of every double-pancake coil and every single turn was calculated.The trend of the index loss of the magnet with increasing current was studied.The magnetic field on the magnet was varied by adding iron yokes at the two ends of the magnet.The result from this change shows that the index loss of magnet decreases efficiently with iron yokes.
