Distance measurement error sources in Fourier-based frequency sweeping interferometry using a gas cell for laser frequency sweep speed determination / Sosin, M (CERN ; U. Nottingham) ; Gonzalez Cobas, J D (CERN) ; Isa, M (U. Nottingham) ; Leach, R K (U. Nottingham) ; Mainaud Durand, H (CERN)
Fourier-based frequency sweeping interferometry (FSI) is an interferometric technique, which offers absolute distance measurement based on the detection of interference beat frequencies of reflected signals. Through the multiple beat frequencies detected, Fourier-based FSI performs robust and simultaneous measurements of absolute distances to multiple targets. [...]

Protection Layers Design for the High Luminosity LHC Full Remote Alignment System / Fernández Adiego, Borja (CERN) ; Blanco Viñuela, Enrique (CERN) ; Germinario, Andrea (CERN) ; Mainaud Durand, Helene (CERN) ; Sosin, Mateusz (CERN)
The Full Remote Alignment System (FRAS) is a complex measurement, alignment and control system designed to remotely align components of the Large Hadron Collider (LHC) following its High Luminosity upgrade. The purpose of FRAS is to guarantee optimal alignment of the strong focusing magnets and associated components near the experimental interaction points, while at the same time limiting the radiation dose to which surveyors in the LHC tunnel are subjected.

Geodetic, survey and alignment challenges of the FCC-ee / Mainaud Durand, H (CERN) ; Watrelot, L (CERN ; LSPM, Paris) ; Weyer, B (CERN)
At CERN, each generation of particle accelerators led to theimplementation of new geodetic, survey and alignment methodologiesfollowing the increasing accuracy requirements and the evolution ofsurvey instruments. The Future Circular Collider (FCC), representingthe next generation of particle accelerator, will in its turnrequire new development to ensure the accomplishment of theconstruction of the 91 km tunnel and the correct positioning of themachine components.

First considerations on the supporting structures of FCC-ee booster and collider in the arc regions / Carra, F (CERN) ; Baudin, L (CERN) ; Bauche, J (CERN) ; Artoos, K (CERN) ; Atieh, S (CERN) ; Bertarelli, A (CERN) ; Brunner, O (CERN) ; Capatina, O (CERN) ; Chance, A (Saclay) ; Chemli, S (CERN) et al.
In 2022, the FCC Feasibility Study management mandated aworking group to analyse the best configuration of the FCC-ee tunnelin the arc regions, in view of the construction of a mock-up of thearc half-cell. One of the main and most challenging goals of thestudy, named FCC-ee Arc Half-Cell Mock-up Project, was toperform a preliminary investigation on the principles of supportingthe Short-Straight Sections and dipoles of the half-cells, both forthe booster and for the collider machines.
