Measurement and alignment of the TIDVG5 SPS beam dump
/ Vendeuvre, Camille (CERN) ; Bestmann, Patrick (CERN) ; Barcet, Florian
During the Long Shutdown 2 (LS2 2018-2021) the CERN injector complex was upgraded to meet the future High Luminosity-Large Hadron Collider (HL-LHC) re- quirements. One major activity was the construction and installation of a new beam dump, in the Super Proton Synchrotron (SPS), able to cope with the increasing brightness of the high luminosity beams [...]

SurveyPad, a common interface to Geode & data processing tools
/ Lewandowski, Przemyslaw (CERN) ; Ducceschi, Remi ; Klumb, Francis (CERN)
The metrology and alignment of components installed in accelerators is a very complicated process requiring many calculations to ensure the best performance of the CERN complex. Throughout the years, surveyors at CERN have been relying on several pieces of different offline processing software that were meant to function without an internet con- nection in the tunnels. [...]

Detection of structured laser beam centroid and its use for alignment
/ Dusek, Martin (Liberec Technical University (CZ)) ; Polak, Krystof (Liberec Technical University (CZ)) ; Gayde, Jean-Christophe (CERN) ; Sulc, Miroslav (Liberec Technical University (CZ)) ; Mergelkuhl, Dirk (CERN) ; Niewiem, Witold Grzegorz (ETH Zurich (CH))
A Structured Laser Beam (SLB) [1] is a pseudo-non- diffractive optical beam. Its transverse profile is similar to a Bessel Beam (BB), hence its bright central core is sur- rounded by concentric circles. [...]

A quality assurance approach for the Full Remote Alignment System
/ Herty, Andreas (CERN) ; Dandekar, Mamta Shrikrishna (CERN) ; Fleury, Sarah Agathe (CERN) ; Naegely, Anne Valerie (CERN) ; Rude, Vivien (CERN) ; Sosin, Mateusz (CERN)
The Full Remote Alignment System is a multi-sensor monitoring and alignment system for the position de- termination and adjustment of accelerator components in the High-Luminosity Large Hadron Collider. The objective of this development was the creation of an asset management for equipment of the Full Remote Alignment System that allows a simple, intuitive and time-optimised handling. [...]

Long shutdown 2 LHC smoothing status and data analysis
/ Fuchs, Jean-Frederic (CERN) ; Widuch, Kacper (CERN)
During the two-year Long Shut-Down 2 (LS2), triggered by the LHC Injectors Upgrade (LIU) project, the CERN surveyors took in charge the smoothing of the 27km com- ponents of the LHC to guarantee its best beam aperture and energy performance for the RUN3 between 2022 and 2026. During this large measurement campaign, the roll angle of the LHC components in the Long Straight Section (LSS) as well as their position in vertical and in horizontal direc- tions were measured by direct levelling and stretched wire methods [...]

Towards centimetric Geoid over FCC area: application of the Stokes-Helmert method
/ Weyer, Benjamin (CERN) ; Konan, Hector Sullivan (Ecole Nationale des Sciences Geographiques (FR))
Knowing the local variations of the gravity field is a prerequisite for an accurate accelerator alignment in a Euclidean plane, especially for large machines. Within the scope of the Future Circular Collider (FCC), the proposed next-generation particle collider with a circumference of 91 km, efforts are made to compute a local centimetric geoid. [...]

Full remote alignment system for the High-Luminosity Large Hadron Collider HL-LHC
/ Biedrawa, Piotr (AGH University of Science and Technology (PL)) ; Blanco Vinuela, Enrique (CERN) ; Cala Franco, Clara (CERN) ; Gonzalez Cobas, Juan David (CERN) ; Di Castro, Mario (CERN) ; Donze, Mathieu (CERN) ; Falcao Machado, Joao Luis (CERN) ; Fargier, Sylvain (CERN) ; Fernandez Adiego, Borja (CERN) ; Herty, Andreas (CERN) et al.
The High Luminosity Large Hadron Collider (HL-LHC) is an upgrade of the LHC to achieve instantaneous luminosities, a factor five larger than the LHC nominal values. During the Long Shutdown 3, scheduled between 2026 and 2028, nearly 1.2 km of accelerator components will be replaced by new ones, relying on key innovative technologies [...]
