Abstract

This paper presents the developed quench analysis code and protection circuit design for a superconducting magnet system of 28GHz electron cyclotron resonance (ECR) ion source. The superconducting magnet is composed of a hexapole magnet and four solenoid magnets located outside of the hexapole one. All magnets are wound with NbTi composite wire and impregnated by epoxy. By using the developed characteristic analysis code, the normal zone resistance, decaying current and temperature rising can be estimated during quench. Also, the stored magnetic energy is successfully consumed from the series resistor of the designed protection circuit. The analytical results are compared with the experimental results to verify the developed quench analysis code and protection circuit.

RISP 28GHz ECR离子源超导磁体系统的失稳分析与保护电路设计

本文介绍了28GHz电子回旋共振(ECR)离子源超导磁体系统的猝灭分析程序和保护电路设计。超导磁体由一个六极磁体和位于六极磁体外的四个螺线管磁体组成。所有磁体均以NbTi复合丝缠绕，并以环氧树脂浸渍。利用开发的特性分析程序，可以估计出淬火过程中的正区电阻、衰减电流和温升。此外，所设计的保护电路的串联电阻成功地消耗了存储的磁能。将分析结果与实验结果进行比较，验证了所开发的失稳分析代码和保护电路的正确性。
