Design of High-Precision lifting system for the HL-LHC Heavy Components in the interaction region / Micolon, Frederic ; Sosin, Mateusz (CERN)
Given the high radiation level and the tight alignment tolerances, the HL-LHC interaction region components are designed to be realigned remotely using motorized supporting jacks, as human interventions in these zones must be limited to the strict minimum. A position adjustment system will allow a vertical and horizontal displacement of each jack support by at least +/- 2.5 mm with a resolution of less than 10 μm [...]

In the framework of the High-Luminosity Large Hadron Collider (HL-LHC) project, larger and shielded beam screens will be installed in the beam pipe of the superconducting magnets of the insertion next to the ATLAS and CMS detectors. The beam screen is a complex assembly that guarantees the vacuum requirements while shielding the magnet cold mass from the induced heat loads. [...]
