| 摘 要： | 本论文对高温超导磁体指数损耗(HTS index loss)的特点进行了分析.通过数值模拟,研究了由20个双饼组成的高温超导磁体在20k的温度下磁体的指数损耗,对每个双饼以及每匝线圈的指数损耗进行了计算,对整个磁体的指数损耗随电流变化情况进行了研究.在磁体的两端加上铁轭改变磁场的分布后,可以看出,铁轭可以有效地减少磁体上的指数损耗.

| Abstract: | An analysis of the characteristic on HTS magnet index loss is carried out. The index loss of a HTS magnet including 20 double pancakes is analyzed at 20 K using numerical simulation. The index losses of every single pancake and turn are calculated. The trend of the index loss of the magnet with increasing current is studied. The magnetic field on the magnet is varied by adding iron yoke at the end of the magnet. The result from this change shows that the index loss of magnet is decreasing efficiently whit iron yoke. |
