  The HXCS is a ded­i­cated co­her­ent beam­line of the High En­ergy Pho­ton Source (HEPS). The ex­per­i­men­tal setup of the end­sta­tion mainly in­cludes two de­vices: CDI/WAXS XPCS and SAXS XPCS. To achieve high sta­bil­ity re­quire­ments, the CDI/WAXS XPCS de­vice use a nano-fo­cus­ing AKB mir­rors sys­tem, which will focus hard x-rays to a focal spot as small as 100 nm with a small work­ing dis­tance of 64 mm. In the nar­row work­ing dis­tance, AKB mir­ror cham­ber and sam­ple cham­ber are de­signed as a unit but sep­a­rated from the mid­dle. And the de­vice is de­signed with two sets of switch­able sam­ple table, in order to flex­i­bly carry out four co­her­ent tech­niques. Due to high sta­bil­ity, the CDI/WAXS XPCS de­vice is strin­gent de­signed for high stiff­ness, high tem­per­a­ture sta­bil­ity and metrol­ogy. Be­sides, the other im­por­tant equip­ments of the beam­line in­clude a 1.5m WAXS tube and a 14m SAXS tube. For high-res­o­lu­tion ap­pli­ca­tions, the WAXS tube can be ro­tated around the sam­ple in the hor­i­zon­tal and ver­ti­cal plane by 45°and the SAXS tube can ad­just dis­tance and an­gu­la­tion. At pre­sent, the whole ex­per­i­men­tal setup is de­signed ac­cord­ing to the fine me­chan­i­cal de­sign which can meet the ex­per­i­men­tal re­quire­ments.
