摘要
介绍北京正负电子对撞机注入器复测的精度要求，阐述采用波带权激光准直系统与精密水准测量相结合的方法，进行注入器复测的观测、数据处理与调整。根据复测数据分析了隧道地基变形与加速管位置变形及其规律，提出了一些有益的结论与建议。
In this paper, the accuracy requirement of the repetition of linear acceleratorof Beijing electron positron collider (BEPC) is introduced. Based on Laser alignmentsystem, the measurement, data-handling and adjustment of the repetition of linear accelerator are presented. The deformation of tunnel ground and accelerating tubing siteare analysized by data of repetition. Finally, some useful conclusions and suggestionsare also given.
