摘　　要：北京同步辐射装置微束Ｘ射线荧光实验站位于４Ｗ１Ａ白光束线末端，主要仪器设备包括：束流强度监测用电离室系统、狭缝及激光对准光路系统、多维精密样品移动台及其步进马达驱动系统、体视显微镜及电视观测系统、Ｓｉ（Ｌｉ）能量色散谱仪系统等。The synchrotron radiation (SR)microprobe XRF experimental station of Beijing Synchrotron Radiation Facility (BSRF)is located at the end of the 4W1A white SR beam line。The major instruments of the station are: ion chamber system for beam intensity monitor; slits and laser collimation system;multidimensional sample stage andits stepping motor driviing system; tele-microscope and video viewing system; Si(Li)energy dispersive spectrometer.The equipment has very high sensitivity (absoluteMDL, 10-10- 10-13g,relative MDL:N×μg/g-N×0.1μg/g,and relative MDL fortotal reflection XRF is 1- 5ng/g),good spatial resolution (50μm for thick sample,200μm for Bio -tissue). A lot of researches were performed on Geo -Science,Bio-Science,Material Science and so on.,
