摘要
双丝型同步辐射光束位置监测器(PBPM)基于光电子发射原理,通过光敏丝探测同步辐射的强度。在扫描模式下可以方便地获得光束的强度分布情况,在静止状态时则可以通过两根丝上光电流大小的相对变化对同步辐射光束的位置进行实时监测。本文介绍了这种双丝型PBPM的原理、设计、参数优化及误差分析,及其在北京同步辐射装置上的应用情况。
In this paper, we describe a double-wire photon beam position monitor (PBPM) for monitoring synchrotron radiation (SR) intensity by photosensitive wire based on the principle of photoemission. In scan mode, the SR intensity distribution can be easily obtained. In the smile state, we can realize real-ilme monitoring of the SR beam position by changes of the photoelectron currents of the two wire sensors. The principle, design, parametric optimization, error analysis, and its application in Beijing Synchrotron Radiation Facility (BSRF) are given.
