The status of the FCC-ee optics tuning / van Riesen-Haupt, Léon (Ecole Polytechnique, Lausanne) ; Franchi, Andrea (ESRF, Grenoble) ; Faus-Golfe, Angeles (IJCLab, Orsay) ; Chance, Antoine (Paris, CEA) ; Dalena, Barbara (Paris, CEA) ; Järmyr Eriksson, Carl (CERN) ; Carli, Christian (CERN) ; Garcia Jaimes, Cristobal Miguel (Ecole Polytechnique, Lausanne) ; Shatilov, Dmitry (CERN) ; Musa, Elaf (DESY) et al.
With a circumference of approximately 91 km, the Future Circular electron-positron Collider, FCC-ee, aims for unprecedented luminosities at beam energies from 45.6 to 182.5 GeV. A major challenge is reaching its design performance in the presence of magnet misalignments and field errors. [...]

Review of MAD-X for FCC-ee studies / Simon, Guillaume (CERN ; IJCLab, Orsay) ; Faus-Golfe, Angeles (IJCLab, Orsay) ; van Riesen-Haupt, Léon (Ecole Polytechnique, Lausanne) ; De Maria, Riccardo (CERN) ; Pieloni, Tatiana (Ecole Polytechnique, Lausanne)
The design of the electron-positron Future Circular Collider (FCC-ee) challenges the requirements on optics codes (like MAD-X) in terms of accuracy, consistency, and performance. Traditionally, MAD-X uses a transport formalism by expanding the transfer map about the origin up to second order to compute optics functions and synchrotron radiation integrals in the TWISS and EMIT modules.

Xsuite: an integrated beam physics simulation framework / Iadarola, Giovanni (CERN) ; Latina, Andrea (CERN) ; Abramov, Andrey (CERN) ; Montanari, Carlo Emilio (CERN) ; Droin, Colas (CERN) ; Di Croce, Davide (Ecole Polytechnique, Lausanne) ; Demetriadou, Despina (CERN) ; Soubelet, Felix (CERN) ; Van der Veken, Frederik (CERN) ; Sterbini, Guido (CERN) et al.
Xsuite is a modular simulation package bringing to a single flexible and modern framework capabilities of different tools developed at CERN in the past decades notably MAD-X Sixtrack Sixtracklib COMBI and PyHEADTAIL. The suite consists of a set of Python modules (Xobjects, Xpart, Xtrack, Xcoll, Xfields, Xdeps) that can be flexibly combined together and with other accelerator-specific and general-purpose python tools to study complex simulation scenarios.

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% [...]

Building an accelerator, from engineering to alignment / De Maria, Riccardo (speaker) (CERN)
Engineering tools are essential to the construction of an accelerator. They are used from the very early stages in the processes that bring objectives and ideas to a conceptual design, engineering specifications, mechanical models, installation plans and finally installation with fine-tuned alignment. The talk uses the HL-LHC project to illustrate a selection of tools that are used in the processes that took and are taking place to bring the HL-LHC project to completion..

Mitigating Collimation Impedance and Improving Halo Cleaning with New Optics and Settings Strategy of the HL-LHC Betatron Collimation System / Lindström, Bjorn (CERN) ; Bruce, Roderik (CERN) ; Buffat, Xavier (CERN) ; De Maria, Riccardo (CERN) ; Giacomel, Lorenzo (CERN) ; Hermes, Pascal (CERN) ; Mirarchi, Daniele (CERN) ; Mounet, Nicolas (CERN) ; Persson, Tobias (CERN) ; Redaelli, Stefano (CERN) et al.
With High Luminosity Large Hadron Collider (HL-LHC) beam intensities, there are concerns that the beam losses in the dispersion suppressors around the betatron cleaning insertion might exceed the quench limits. Furthermore, to maximize the beam lifetime it is important to reduce the impedance as much as possible. [...]

FCC-ee is a proposed lepton collider with a circumference close to 100 km to produce an unprecedented amount of luminosity. The FCC-ee optics tuning working group is addressing one of the most critical aspects of the FCC-ee, that is the recovery of the optics design performance in presence of realistic imperfections.
