  The long versatile detector tube system for small-angle X-ray scattering meets the experimental conditions of -5-50° wide-angle X-ray scattering (WAXS), 0.04-6° small-angle X-ray scattering (SAXS) and 0.001-0.1° ultra-small-angle X-ray scattering (USAXS), record the same change process of the same sample, and obtain comprehensive structural information of atomic size, nanometer size and micron size, which can be applied to nanomaterials, mesoporous materials, biological macromolecules, polymers and other fields. The size of the tube system is 26760×1945×2565 mm,and consists of four parts: WAXS device, SAXS device, USAXS device and vacuum chamber. The vacuum chamber is assembled by connecting and assembling parts such as thick and fine pipes, bellows, heads and vacuum valves, with a length of 13775 mm and an inner diameter of 1500mm. The thin pipe is 7740 mm long and has an inner diameter of 300 mm. The design scheme of the tube system is committed to ensuring that the distance between the SAXS detector and the sample is continuously adjustable within the range of 1-13.5 m in vacuum environment, and the straightness of the 13840 mm long track of the SAXS device is better than 1 mm.

  Pink SAXS (small angle X-ray scattering) station is dedicated to performing scattering experiments. A classical planar undulator is adopted as the beam source. The pink beam from the fundamental radiation of the undulator at the range of 8-12keV will be used directly after reflected by a pure silicon reflector. The high flux pink beam will be used to perform high time-resolution SAXS experiments. Monochromatic beam, which is obtained by a normal horizontal monochromator, also can be used alternately to perform high energy resolution experiments. Monochromatic beam and pink beam can be switched through moving in and out of the monochromator. The scattering background is reduced effectively using three sets of scatterless slits. Three diamond compound refractive lenses with different curvatures are employed to focus the 12keV monochromatic beam at sample position, detector position and infinite position respectively. A totally 24 meters long vacuum detector tube is adopted as SAXS camera. Three vacuum compatibility EIGER detectors are equipped at different positions to collect WAXS, SAXS and USAXS signals respectively. Then simultaneous USAXS/SAXS/WAXS measurement could be performed.
