摘要

摘要: 云光二号加速器采用感应电压叠加技术路线，全系统包含12台Marx发生器、24条水线、12级感应腔和1条长磁绝缘传输线，由于装置规模大、级数多、结构复杂，为保证整体装配精度，尤其是感应腔和磁绝缘传输线的同轴度，对准直测量技术提出了很高的要求。针对国外同类装置测量系统复杂、过程繁琐的技术缺陷，提出了以激光跟踪仪为核心测量手段的全系统准直测量技术方案，分别完成了发生器输出法兰、感应腔导轨、磁绝缘传输线及其导轨的准直测量和调节，尤其是设计了能够实现双向内孔定心的靶标座测量机构，高精度、高效率实现了12级感应腔同轴串联的准直测量调节，为更大规模装置建设奠定了良好的技术基础。

Abstract: Yunguang II accelerator adopts induction voltage adder technique route. The whole system consists of 12 Marx generators, 24 water lines, 12 induction cavities and a long magnetically insulated transmission line. Because of its large scale, many series and complex structure, the alignment measurement technique is required to ensure the whole assembly precision, especially the coaxiality of the induction cavity and the magnetically insulated transmission line. Aiming at the technical defects of complex and complicated measuring system of similar equipment in foreign countries, an all-system alignment measuring scheme using laser tracker as the core means is put forward. The alignment and adjustment of the generator output flange, induction cavity guide rail, magnetically insulation transmission line and its guide rail are completed respectively, especially a measuring mechanism of target base which can realize double-direction inner hole centering is designed. With high precision and efficiency, the alignment measurement and adjustment of 12-stage induction cavity in series is realized, which lays a good technical foundation for the construction of larger-scale facilities.
