由于空间狭小且不能通视, 分离扇回旋加速器的检修与准直复位一直困扰着机械准直人员。加上时间紧张, 如何快速准确找到故障原因和准确复位是保证加速器正常运行所必须思考的问题。分析了磁通道的工作原理和传动机制, 建立了有效的传动监测模型, 标定并改善了电机的传动性能。基于多重坐标系转换总结出一种快速安装的方法, 快速复位精度满足物理要求, 保证束流的顺利引出。该方法精度满足实验要求(不超过0.2 mm), 具有可继承性, 能够为相关加速器类似元器件的检修与准直工作提供依据。

Due to the small space and invisibility in MSE3, the alignment of MSE3 of separated sector cyclotron remains a longstanding challenging for the aligned personnel. Coupled with the compressed time, to quickly and accurately find MSE3’s fault and realign its position is essential for the regular operation of the accelerator. This paper analyzes the principle of MSE3 and its transmission mechanisms, and establishes an effective model to standardize the drive motor. Furthermore, it develops a rapid realignment method based on multiple coordinate system transformation. The method can provide a basis for overhaul and alignment of similar component in related accelerators.
