EuroCirCol合作正在设计一种16TNb3Sn偶极子，可以用作100公里长100TeV强子-强子对撞机的主弯曲磁铁。出于经济原因，磁体需要尽可能紧凑，需要优化不同磁场区域中的电缆横截面。这导致了非常高的存储能量密度，并对磁体保护提出了严重的挑战，如果发生失超，即绕组中的超导电性突然丧失。因此，磁铁设计必须考虑到从设计的最早阶段起就由失超保护设置的限制。在本文中，我们描述了在为16T偶极子设计开发不同选项的过程中如何考虑失超保护方面的问题。我们讨论了热点温度和电压的假定安全值，以及保护系统的效率。我们描述了为失超分析开发的工具，以及它们在磁体设计中的使用最终将如何确保磁体的安全运行。
The EuroCirCol collaboration is designing a 16 T Nb 3 Sn dipole that can be used as the main bending magnet in a 100 km long 100 TeV hadron-hadron collider. For economic reasons, the magnets need to be as compact as possible, requiring optimization of the cable cross section in different magnetic field regions. This leads to very high stored energy density and poses serious challenges for the magnet protection in case of a quench, i.e., sudden loss of superconductivity in the winding. The magnet design therefore must account for the limitations set by quench protection from the earliest stages of the design. In this paper we describe how the aspect of quench protection has been accounted for in the process of developing different options for the 16 T dipole designs. We discuss the assumed safe values for hot spot temperatures and voltages, and the efficiency of the protection system. We describe the developed tools for the quench analysis, and how their usage in the magnet design will eventually ensure a secure magnet operation.
