Abstract：
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.
