  In the frame­work of the High-Lu­mi­nos­ity Large Hadron Col­lider pro­ject at CERN, a Full Re­mote Align­ment Sys­tem (FRAS) is under de­vel­op­ment, in­te­grat­ing a range of so­lu­tions for the re­mote po­si­tion­ing of ac­cel­er­a­tor com­po­nents. An im­por­tant com­po­nent of FRAS is the mo­tor­ized ac­tu­a­tor al­low­ing the re­mote ad­just­ment of ac­cel­er­a­tor com­po­nents with a mi­crom­e­ter res­o­lu­tion. These ac­tu­a­tors need to ful­fill mul­ti­ple re­quire­ments to com­ply with safety rules, and be highly re­li­able and main­te­nance free as thus are lo­cated in a harsh en­vi­ron­ment. The in­te­gra­tion of the safety func­tions re­quired for the FRAS was cru­cial, with the mo­tor­ized ac­tu­a­tors able to pro­vide an ab­solute po­si­tion mon­i­tor­ing of the avail­able stroke, in­te­grat­ing elec­tri­cal end-stops and hav­ing an em­bed­ded me­chan­i­cal stop as a hard­ware safety layer. In ad­di­tion, the de­sign has been elab­o­rated to allow a rapid, in-situ read­just­ment of the nom­i­nal stroke in order to cope with po­ten­tial read­just­ment re­quire­ments, fol­low­ing long-term drifts caused by ground mo­tion. This paper de­scribes the de­sign ap­proach, pro­to­typ­ing and qual­i­fi­ca­tion of these mo­tor­ized ac­tu­a­tors.

  In order to op­ti­mize align­ment ac­tiv­i­ties in a highly ra­dioac­tive en­vi­ron­ment, the Ge­o­detic Metrol­ogy Group at CERN has de­vel­oped a stan­dard­ized fea­tur­ing 6 de­gree of free­dom (DoF) Uni­ver­sal Ad­just­ment Plat­form (UAP). After a first pro­to­typ­ing phase in 2021 with a man­ual UAP, the de­sign has been con­sol­i­dated and is now com­pat­i­ble with the in­stal­la­tion of mo­tor­ized ac­tu­a­tors to form a re­motely ad­justable 5-6 DoF plat­form able to per­form po­si­tion­ing with mi­crome­tre res­o­lu­tion. This paper pre­sents the UAP and re­lated mo­tor­ized ac­tu­a­tor de­vel­op­ment, elab­o­rated in the frame of the High-Lu­mi­nos­ity Large Hadron Col­lider pro­ject. The me­chan­i­cal in­te­gra­tion ap­proach, de­sign so­lu­tions, and test re­sults are dis­cussed.
