摘要

对同步辐射光源不稳定性的监测一直是北京同步辐射装置（BSRF）在运行中急需的技术手段。随着北京正负电子对撞机升级改造工程的不断推进

光源的性能得到了很大提高

对光源不稳定性的监测也提出了更高的要求。一种双楔片型的同步辐射光束位置探测器在北京同步辐射装置上得到发展

并在前端区安装和使用。它可以有效监测同步光束位置的10μm级的变化

为降低光源不稳定性、提高数据质量提供了依据。本文详细描述了双楔片型同步辐射光束位置监测器的设计原理、参数优化以及误差分析

并介绍了这种监测器在BSRF的应用情况。

Abstract

Instability monitoring of synchrotron radiation (SR) was a problem in operating the Beijing Synchrotron Radiation Facility (BSRF). With progresses in the Beijing Electron Positron Collider (BEPC) upgrading project

great performance improvement of the SR source is required

too

hence the need of the monitoring the source instability. A photon beam position monitor (PBPM) of double wedge-blades type in BSRF has been developed and used for the front end zone. The PBPMs can effectively monitor 10 μ m change in the SR beam position

and provide important guarantee of the light stability and the quality of experiment data. In this paper

we report physical design

parameter optimization and error analysis of the PBPMs. Descriptions on their applications in the BSRF are given briefly.
