  In syn­chro­tron ra­di­a­tion fa­cil­i­ties such as the High En­ergy Pho­ton Source (HEPS) beam­line, thou­sands of mo­tor­ized ac­tu­a­tors are equipped on dif­fer­ent op­ti­cal de­vices, such as K-B mir­rors, mono­chro­ma­tor and trans­fo­ca­tors, in order to ac­quire the spec­i­fied prop­er­ties of X-ray. The mo­tion con­trol sys­tem, as a part of the ul­tra-pre­ci­sion mecha­tron­ics de­vices, is used to pre­ci­son po­si­tion­ing con­trol, which not only has abil­ity to re­al­ize basic mo­tion func­tions but also can han­dle com­plex mo­tion con­trol re­quire­ments. HEPS has de­vel­oped a stan­dard­ized mo­tion con­trol sys­tem(MCS) for syn­chro­tron ra­di­a­tion ap­pli­ca­tions. In this paper, The struc­ture of hard­ware and soft­ware of MCS will be pre­sented, and some ap­pli­ca­tions are demon­strated in de­tail.

  HEPS is the first low emit­tance 4th gen­er­a­tion light source in China, as mono­chro­ma­tors are often lim­it­ing the per­for­mance of beam­lines, many chal­lenges are faced to pre­serve the qual­ity of the beam. In order to meet the strin­gent and ver­sa­tile re­quire­ments of 12 in house de­vel­oped mono­chro­ma­tors for dif­fer­ent beam­lines, sev­eral core tech­nolo­gies have been stud­ied and de­vel­oped. Sta­bil­ity con­sid­er­a­tions, vi­bra­tion mea­sure­ment sys­tem and meth­ods are in­tro­duced, sta­bil­ity below 10 nrad RMS are mea­sured for op­er­a­tion con­di­tions by laser in­ter­fer­om­e­ters. Ther­mal re­sis­tance study at low tem­per­a­ture was car­ried out, en­abling more ac­cu­rate FEA of cool­ing. Clamp­ing de­for­ma­tion of crys­tals at low tem­per­a­ture are ex­per­i­men­tally stud­ied, slope er­rors below 0.1 mi­cro­ra­dian RMS are mea­sured. De­sign and test re­sults on dif­fer­ent types of mono­chro­ma­tors will also be pre­sented. Re­sults show that the in house de­vel­oped mono­chro­ma­tors are able to meet the re­quire­ments of HEPS beam­lines.
