LHC optics commissioning in 2023 and 2024 / Persson, Tobias (CERN) ; Wegscheider, Andreas (CERN) ; Fol, Elena (CERN) ; Maclean, Ewen (CERN) ; Carlier, Felix (CERN) ; Soubelet, Felix (CERN) ; Trad, Georges (CERN) ; Keintzel, Jacqueline (CERN) ; Cardona, Javier (Columbia U.) ; Dilly, Joschua (CERN) et al.
The LHC machine configuration was changed in 2023 compared to previous years, requiring a new set of optics configurations to be measured and corrected. A telescopic optics was deployed in energy the ramp for the first time, which gave rise to a beta-beating of up to 25% [...]

Operation of the LHC during the 2023 proton run / Calia, Andrea (CERN) ; Salvant, Benoit (CERN) ; Mirarchi, Daniele (CERN) ; Nisbet, David (CERN) ; Jacquet, Delphine (CERN) ; Métral, Elias (CERN) ; Bravin, Enrico (CERN) ; Trad, Georges (CERN) ; Wenninger, Jorg (CERN) ; Solfaroli, Matteo (CERN) et al.
In 2023 the LHC restarted after the yearly winter shutdown with a new machine configuration optimized for intensities of up to 1.8e+11 protons per bunch. In the first two months of the 2023 run the bunch intensities were pushed up to 1.6e+11 protons per bunch until a severe vacuum degradation, caused by a damaged RF bridge, occurred close to the ATLAS experiment.

Evolution of special LHC optics configurations Run 3 update / Efthymiopoulos, Ilias (CERN) ; Wegscheider, Andreas (CERN) ; Mirarchi, Daniele (CERN) ; Maclean, Ewen (CERN) ; Carlier, Felix (CERN) ; Van der Veken, Frederik (CERN) ; Dilly, Joschua (CERN) ; Le Garrec, Mael (CERN) ; D'Andrea, Marco (CERN ; INFN, Legnaro) ; Solfaroli, Matteo (CERN) et al.
The Large Hadron Collider (LHC) employs special optics and configurations, alongside low-beta* collision optics, to address specific experimental requirements. These include calibrating luminosity monitors (vdM) and facilitating forward physics measurements in TOTEM and ALFA experiments (high-beta). [...]

LHC Upgrades in preparation of Run 3 / Arduini, G (CERN) ; Baglin, V (CERN) ; Bartosik, H (CERN) ; Bottura, L (CERN) ; Bracco, C (CERN) ; Bradu, B (CERN) ; Bregliozzi, G (CERN) ; Brodzinski, K (CERN) ; Bruce, R (CERN) ; Calviani, M (CERN) et al.
The Large Hadron Collider (LHC) Long Shutdown 2(2019–2021), following LHC Run 2, was primarily dedicated to theupgrade of the LHC Injectors but it included also a significantamount of activities aimed at consolidation of the LHC machinecomponents, removal of known limitations and initial upgrades inview of the High-Luminosity LHC (HL-LHC) to favour the intensityramp-up during Run 3 (2022–2025). An overview of the majormodifications to the accelerator and its systems is followed by asummary of the results of the superconducting magnet trainingcampaign to increase the LHC operation energy beyond the maximumvalue of 6.5 TeV reached during Run 2.

60° phase advance optics measurements in the Large Hadron Collider at CERN / Keintzel, J (CERN) ; Fartoukh, S (CERN) ; Le Garrec, M (CERN) ; Persson, T H B (CERN) ; Solfaroli, M (CERN) ; Todesco, E (CERN) ; Tomás, R (CERN) ; Wenninger, J (CERN)
The Large Hadron Collider (LHC) arcs have been designed for a FODO optics with roughly 90° betatron phase advance per arc cell, but not necessarily with exactly the same optics in the eight sectors of the ring. Measuring an optics with a significantly different arc cell phase advance, e.g. [...]

Operational $\beta$* levelling at the LHC in 2022 and beyond / Hostettler, M (CERN) ; Calia, A (CERN) ; Fartoukh, S (CERN) ; Jacquet, D (CERN) ; Wenninger, J (CERN)
During the third run period of the CERN Large Hadron Collider (LHC), as well as for the future High-Luminosity LHC era, luminosity levelling by beta* is a key technique to control the pile-up in the high-luminosity experiments ATLAS and CMS while maintaining Landau damping through the head-on beam-beam interaction. This implies changing the machine optics in the interaction regions while keeping high-intensity beams in collision and the experimental detectors in their data taking configuration. [...]

LHC Triplet Task Force Report / Arduini, Gianluigi (CERN) ; Bradu, Benjamin (CERN) ; Brodzinski, Krzysztof (CERN) ; Bruce, Roderik (CERN) ; Cerutti, Francesco (CERN) ; Ciccotelli, Alessia (University of Manchester (GB)) ; Deferne, Guy (CERN) ; Fartoukh, Stephane (CERN) ; Fessia, Paolo (CERN) ; Garion, Cedric (CERN) et al.
The excellent performance of the Large Hadron Collider (LHC) and the extension of Run 3 by one year have led to a significant increase of the expected integrated luminosity by the end of its operation and before the start of the High Luminosity LHC (HL-LHC), exceeding the design LHC integrated luminosity of 300 fb−1 for which the final focus region has been designed.

Machine Configuration for the 2023 Proton Run (MD7003) / Fartoukh, Stephane (CERN) ; Dilly, Joschua Werner (CERN) ; Hostettler, Michi (CERN) ; Iadarola, Giovanni (CERN) ; Jacquet, Delphine (CERN) ; Kostoglou, Sofia (CERN) ; Mirarchi, Daniele (CERN) ; Persson, Tobias Hakan Bjorn (CERN) ; Solfaroli Camillocci, Matteo (CERN) ; Sterbini, Guido (CERN) et al.
This note contains a condensed summary of the various beam tests which took place in 2022 in order to validate the machine configuration planned to be deployed for the 2023 proton run of the LHC, including in particular a combined ramp and anti-telescopic squeeze, the rotation of the external crossing angle in LHCb, and beam operation with up to 1.8 × 1011 p/b..
