Development of Trim-rod driving system for CYCIAE-230 superconducting cyclotron

  • 摘要: 在230 MeV超导回旋加速器中,磁场调节棒及其驱动系统是束流调试的重要辅助装置。为满足束流对中和束流引出所需的磁场,设计并研制了16套磁场调节棒及其驱动装置。机械执行机构采用美国Thomson公司的精密直线执行器,其重复定位精度为±0.01 mm,位置传感器采用德国Novotechnik公司的直线位移电子尺,其重复精度为0.002 mm。此外,运动控制采用PLC加直线位移传感器负反馈闭环的方案。在实际工况下,系统定位精度达到0.05 mm,重复精度达到±0.02 mm,优于设计要求。此外,对该系统进行了静电放电测试、电快速瞬变脉冲群测试和浪涌抗扰度测试,结果满足医用电气设备电磁兼容标准YY 0505-2012/IEC 6060 1-1-2:2004的要求。该驱动系统的研制,克服了在强电离辐射、高磁场强度、狭小安装空间的特殊环境中达到高定位精度和高重复精度的难点,对优化束流的径向进动、减小加速区域的相干振荡振幅、提高引出区的束流引出效率等具有重要意义。
