摘　　要：本文介绍应用Labview软件、气体电离室、电流放大器及数据采集卡等仪器设备构成的同步辐射XAFS(X-ray absorption fine structure)光束线站(BL14W1)数据采集系统。该系统利用NI公司开发的新模块DSC module(Datalogging and Supervisory Control Module),实现了在Labview和EPICS(Experimental and Physics Industrial Control System)两个软件系统间数据的快速交换,使光束线控制的标准化和实验站用途的多样化有机结合。用Labview编写了数据采集软件,使该线站成功实现步进(step-by-step)模式和快扫(QXAFS)模式下的XAFS谱的采集。In this paper, we report the development of a data acquisition system of BL14W1 XAFS （X-ray absorption fine structure） beamline at Shanghai Synchrotron Radiation Facility （SSRF）. The data acquisition system includes two ion chambers, two amplifiers, one ADC, Labview software etc. For quick communication between Labview and EPICS, the newly-developed DSC module by National Instruments is used. The XAFS beamline has been a success in accomplishing data acquisition for XAFS spectra in step-by-step mode and Quick XAFS mode.
