基于能量裕度和温度裕度CICC导体数字模拟设计

Numeric simulation design of CICC based on energy margin and temperature margin

CICC(Cable-in-Conduit Conductor)超导体是大型低温超导磁体的首选导体,在大电流和快速变化磁场环境中以及给定稳定性裕度、温度裕度、空隙率等条件下,开展CICC超导体结构的优化设计及稳定性分析是非常重要的。因此,文中针对CICC导体设计问题,提出数字模拟设计的想法;推导了关于CICC导体结构矩阵参数的算法;建立了导体数字模拟的模型;同时将数字模拟设计情况与工程设计值进行了比较和分析,结果二者基本吻合。

CICC has been the first selected conductor for large cryogenic superconducting magnets. It is very important to optimize the CICC configuration and analyse its stability with high current and rapid changing magnetic field and fixed energy margin and temperature margin and void of CICC. So, in this paper the thought for the numeric simulation design is put forward aiming the conductor design, the arithmetic of simulation design of CICC configuration was deduced, and the model of simulation design was built. The simulation outcome was compared with that of engineering design. The comparing results are encouraged.
