  The re­search sta­tus of a grat­ing mono­chro­ma­tor for soft X-ray self-seed­ing ex­per­i­ment at SHINE has been pre­sented in this paper. The mono­chro­ma­tor sys­tem in­cludes the vac­uum cav­ity, op­ti­cal el­e­ments, and me­chan­i­cal move­ment de­vices. Until now, the vac­uum cav­ity has fin­ished the man­u­fac­tured process com­pletely, the op­ti­cal mir­rors have fin­ished ma­chin­ing and mea­sured by the lon­gi­tu­di­nal trace pro­filer (LTP) and atomic force mi­cro­scope (AFM). To make sure the mono­chro­ma­tor sys­tem can achieve an op­ti­cal res­o­lu­tion of 1/10000 at the pho­ton en­ergy of 700-1300eV, the sys­tem has been in­te­grated and tested re­cently. In this year, the pre­vi­ous on­line ex­per­i­ment will be per­formed in the shang­hai soft X-ray free-elec­tron laser (FEL) user fa­cil­ity.

  The pre­lim­i­nary de­sign and sim­u­la­tion re­sults of EEHG cas­caded har­monic las­ing for the SXFEL user fa­cil­ity have been pre­sented in this paper. Using the basic seeded beam­line of the SXFEL user fa­cil­ity, the de­signed pa­ra­me­ters are op­ti­mized to ob­tain full co­her­ent FEL out­put at the 90th har­monic of a 265 nm seed laser. Ac­cord­ing to the de­signed pa­ra­me­ters and the lay­out of the SXFEL user fa­cil­ity, the de­tailed sim­u­la­tions are car­ried out, the re­sults show that the seeded beam­line of the SXFEL user fa­cil­ity can gen­er­ate 2.93 nm full co­her­ent ra­di­a­tion by the pro­posed method, which in­di­cates that the method can ex­tend the pho­ton en­ergy range of a seeded FEL and the method can be achieved at the SXFEL user fa­cil­ity.
