Abstract： Background : Two x-ray diffractometers produced by HUBER company have been installed at BL02U2 of Shanghai Synchrotron Radiation Facility (SSRF). Purpose : In order to further meet the needs of users for grazing incidence diffraction experimental methods, a new grazing incidence diffractometer was installed  between the two HUBER diffractometers. Methods : This paper mainly introduces the overall scheme of the grazing incidence diffractometer, and discusses in detail several important modules such as high-precision, high-load and large-stroke linear stage, three-dimensional adjustment platform for detector, sample stage system, and the control system. Results : The compatible operation of three diffractometers was realized, and the typical experimental result of the grazing incidence diffractometer with MoS₂ sample was introduced as an example. Conclusions : The grazing incidence x-ray diffractometer developed has been operated more than two years, and expands the experimental platform for material surface science research at SSRF.
