介绍了μ子电离冷却实验（MICE）冷却通道耦合磁体所选用的被动失超保护系统。MICE耦合磁体将同时采用两种失超保护方法。耦合磁体中最重要的失超保护方法是线圈的细分。冷二极管和电阻器被放置在细分两端，以降低对地电压和热点温度。第二种失超保护方法是从心轴回淬，这加速了线圈内正常区域的扩展。将回淬与线圈细分相结合将进一步降低热点温度。本文探讨了线圈细分数、磁体内失超传播速度和分流电阻对失超过程的影响。
This paper describes the passive quench protection system selected for the muon ionization cooling experiment (MICE) cooling channel coupling magnet. The MICE coupling magnet will employ two methods of quench protection simultaneously. The most important method of quench protection in the coupling magnet is the subdivision of the coil. Cold diodes and resistors are put across the subdivisions to reduce both the voltage to ground and the hot-spot temperature. The second method of quench protection is quench-back from the mandrel, which speeds up the spread of the normal region within the coils. Combining quench back with coil subdivision will reduce the hot spot temperature further. This paper explores the effect on the quench process of the number of coil sub-divisions, the quench propagation velocity within the magnet, and the shunt resistance.
