本文以一个10米长的余弦-θ型超导磁体为例，介绍了强子对撞机用长高场Nb/sub 3/Sn超导磁体的设计研究。的问题和并发症进行了讨论，在比较短的磁铁1米长，使用MIIT计算和淬火模拟。由于高场Nb/sub 3/Sn磁体中的储能相当大，因此必须密切关注所有设计细节，尤其是储能的提取。模拟线圈表面上加热器的广泛使用，以将能量倾倒在线圈主体本身上。Nb/sub 3/Sn超导电缆的MIIT值应该做得大以安全运行。这是通过增加铜的比例来实现的。根据这项研究的结果，11.5特斯拉的磁铁可能是一个实际的加速器高场磁铁的设计的限制情况。
Design studies for long high field Nb/sub 3/Sn superconducting magnets for hadron colliders are described, taking a 10 meter magnet with a cosine-theta type coil as an example. The problems and complications are discussed in comparison with short magnets of 1 meter length, using MIIT calculations and quench simulation. As the stored energy in the high field Nb/sub 3/Sn magnets is quite large, close attention must be paid to all design details, and especially the extraction of the stored energy. The extensive use of heaters on the coil surface is simulated to dump the energy on the coil body itself. The MIIT value of the Nb/sub 3/Sn superconducting cable should be made large for safe operation. This is done by increasing the copper ratio. According to the results of this study, an 11.5 Tesla magnet might be the limiting case for the design of a practical accelerator high field magnet.
