142.8MHz次谐波聚束腔的结构优化设计

介绍了兰州重离子加速器冷却储存环工程主环注入线四极磁铁谐波测磁系统和谐波磁场测量结果.分析了磁铁误差产生的原因以及磁铁加工存在的问题和注意事项 The rotating coil measurement system and the measurement results of quadrupoles for CSRm injection beam line are introduced. The reasons causing the high order harmonic components are analyzed. The short circuit of magnet coils will cause sextupole component and the twists of magnet core will affect the octupole component. Otherwise, the chamfering also makes a great impact on the sextupole and octupole components, and some results are involved too.国家重大科学工程项
