  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.
