摘要 介绍了在北京同步辐射生物大分子线站1W2B上新建立的稳定性监测系统的结构和初步应用结果。该系统利用优化设计的双刀片型束流位置监视器(BPM,beam position monitor)和双丝型BPM,结合荧光靶、电离室、荧光探测器等装置,对实验期间光束线的前端区、束线段和样品处三个环节的同步光变化情况进行监测,并及时发现入射光不稳定的来源。另外,通过该系统还得到插入件内电子轨道的变化情况,为北京同步辐射装置建立轨道慢反馈调节系统提供了重要依据。 In this paper we present the structure and primary results of a stability monitor system, which is newly constructed for a macromolecule crystallography station (1W2B) of Beijing Synchrotron Radiation Facility (BSRF). The system consists of optimized double-blades beam position monitor (BPM), double-wires BPM, fluorescence target, ion chamber, and fluorescence detector etc. It monitors the incident beam at front end and sample position and finds the source of beam instability immediately. Otherwise, by virtue of the system, the position of the electron orbit in insertion device can also be monitored in real time that gives an important advice of building slow feedback system of BSRF.
