摘要

T OKAM AK核聚变装置要实现稳态运行

需要靠超导磁体及导体的稳定性

而C ICC(C AB LE-IN-CONDU IT CONDUCTOR)导体是低温超导磁体的首选磁体

因此需要研究C ICC在大电流和快速变化磁场环境下的低温稳定性.针对这一目的

首先研究了C ICC的稳定性机理

并对铌三锡超和铌钛超导材料给出经验设计公式;然后编程对分流温度、温度裕度、能量裕度进行计算

接着模拟出随运行电流变化的稳定性曲线

并把结果保存到数据库.同时对工程设计值和模拟分析及计算结果进行比较和分析

二者基本吻合.显然

这为C ICC设计提供了极大的方便.

Abstract

Tokamak nuclear fusion device depends on superconductor magnet and its stability to keep the device steady.Nowadays

CICC is the first selected conductor for large cryogenic superconductor magnet;it is necessary to study the cryogenic operation stability of CICC under high current and in rapidly changing magnetic field.Aiming at the stability mechanism of CICC and after giving the experical design formula of some material

the paper gives calculation of sharing current temperature

temperature margin and energy margin

and draws simulation curve.Then

the result is saved into database.Finally

after compared the designed value with the result of simulation

almost the same conclusions are found.The research offers help to the design of CICC in the future.
