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.

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% [...]

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). [...]

Optics for Landau Damping with Minimized Octupolar Resonances in the LHC
/ Wenninger, J (CERN) ; Solfaroli, M (CERN) ; Nissinen, T (CERN) ; Hostettler, M (CERN) ; Horney, S (CERN) ; Chudoba, F (CERN) ; Tomás García, Rogelio (CERN) ; Carlier, Felix (CERN) ; Deniau, Laurent (CERN) ; Dilly, Joschua (CERN) et al.
Operation of the Large Hadron Collider (LHC) requires strong octupolar magnetic fields to suppress coherent beam instabilities. The amplitude detuning that is generated by these octupolar magnetic fields brings the tune of individual particles close to harmful resonances, which are mostly driven by the octupolar fields themselves. [...]

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..
