北京正负电子对撞机直线加速器安装的精密测量

Precision Instullation Measurement in the Linac of Beijing Electron-Positron Collider

本文介绍为北京正负电子对撞机安装直线加速器所进行的波带板激光准直测量,以及为对测量结果校核所进行的尼龙线准直测量和精密水准测量。并论述了各种准直测量的精度。

This paper introduces the laser alignment measurement applied to the installation of the Linac of BeijingElectron-Positron Collider (BEPC), and describes nylon line alignment measurement and precision levelmeasurement used for checking and adjusting the results of the laser alignment measurement. In addition,the accuracy for the above-described measurement is also discused.
