Design of a High Precision Lifting System for the HL LHC
2021 11 18 each jack by lifting the ram insi de the guide cylinder, fol lowing which the ring nut is adjusted to retain the chosen height see Fig. 1 . In the HL LHC interaction region, the ram will be per manently supported by the motorized lifting system. Thanks to this, the height can be adjusted remotely without a manual intervention underground.
