High En­ergy Pho­ton Source (HEPS) has been con­structed after decade of re­search. As the first dif­frac­tion-lim­ited stor­age ring light source, many ad­vanced de­vices are ap­plied in this pro­ject, in­clud­ing the Beam Based Align­ment Mover (Mover), which sup­port and ad­just the po­si­tion of the Sex­tu­pole Mag­net. It un­der­takes to re­motely on­line ad­just the po­si­tion of Sex­tu­pole to meet the Phys­i­cal re­quire­ment to cor­rect the op­tics co­ef­fi­cient of Elec­tron beam cur­rent. The po­si­tion­ing ac­cu­racy, at­ti­tude angle, and cou­pled error of Mover with 450kg load strictly pro­posed and tested dur­ing the de­vel­op­ment of Mover. There are three main types of Mover, in­clud­ing Four-layer with slid­ing guide, Three-layer with rolling guide, and Three-layer with slid­ing guide. This paper in­tro­duces the de­vel­op­ment and im­prove­ment of Mover.

  HEPS is a new gen­er­a­tion syn­chro­tron ra­di­a­tion source under con­struc­tion in China. In order to com­plete high-pre­ci­sion in­stal­la­tion of the 1.4km stor­age ring within a lim­ited con­struc­tion pe­riod, it is nec­es­sary to iden­tify and solve po­ten­tial is­sues in var­i­ous as­pects, in­clud­ing opera-tion space, in­stal­la­tion process, align­ment scheme, and unit trans­porta­tion, prior to the reg­u­lar batch in­stal­la­tion. There­fore, a full-process in­stal­la­tion ex­per­i­ment was per­formed and the fea­si­bil­ity of rel­e­vant schemes are ver­i­fied. Batch in­stal­la­tion is cur­rently in progress based on the ex­per­i­men­tal ex­pe­ri­ence.

  The HEPS stor­age ring com­prises 48 7BA (seven-bend achro­mat) cells. There are 37 in­de­pen­dent mag­nets in every cell, of which 5 dipoles are per­ma­nent mag­nets and the rest of mag­nets are all elec­tro­mag­nets in­clud­ing quad-rupoles, D-Q(di­pole-quadru­pole) com­bined mag­nets, sex­tupoles, oc­tupoles and cor­rec­tor mag­nets. These elec-tro­mag­nets with small aper­ture and high mag­netic field gra­di­ent should achieve high ma­chin­ing and as­sem­bly pre­ci­sion. In Oc­to­ber 2023, all stor­age ring elec­tro­mag-nets man­u­fac­tur­ing have been com­pleted. This paper mainly in­tro­duces the me­chan­i­cal de­sign, pro­cess­ing and as­sem­bly, and the man­u­fac­tur­ing is­sues in the ma­chin­ing pe­riod.

  Very low emit­tance of High En­ergy Pho­ton Source (HEPS) de­mands high sta­bil­ity and ad­just­ing per­for­mance of the mag­net sup­port. The align­ment error be­tween gird­ers should be less than 50 ¿m. Based on that, the ad­just­ing res­o­lu­tion of the girder are re­quired to be less than 5 ¿m in both trans­verse and ver­ti­cal di­rec­tions. Be­sides, the nat­ural fre­quency of mag­net sup­port sys­tem should be higher than 54 Hz to avoid the am­pli­fi­ca­tion of ground vi­bra­tions. To ful­fill the re­quire­ments, dur­ing the de­vel­op­ment of the pro­to­type, the struc­ture was de­signed through topol­ogy op­ti­miza­tion, sta­tic analy­sis, grout­ing ex­per­i­ments, dy­namic stiff­ness test and modal analy­sis, and the ra­tio­nal­ity of the struc­ture was ver­i­fied through pro­to­type ex­per­i­ments. Dur­ing the tun­nel in­stal­la­tion, the per­for­mance of the mag­net sup­port sys­tem was again ver­i­fied to be bet­ter than the de­sign re­quire­ments through test work after in­stal­la­tion.
