We have commissioned an ultra-high vacuum chamber for surface structure determination at an undulator beamline BL13XU, SPring-8. As a test experiment, a structure of a Ag (001) surface at a temperature of 25 K has been studied by analyzing x-ray scattering intensities along several surface crystal truncation rods (CTR). Results of least-squares fits to the CTR data show that the top atomic layer was shifted inwards by 0.0011 nm {+-} 0.0003 nm relative to the bulk position.
