Status of the search for a muon EDM using the frozen-spin technique
/ muEDM Collaboration
Despite the many successes of the Standard Model of particle physics, there are stillseveral physical observations that it cannot explain, such as the matter-antimatter asymmetry,non-zero neutrino masses, and the microscopic nature of dark matter. To address these limitations,extensions to the standard model are necessary, and searches for electric dipole moments (EDMs) ofleptons are valuable test. [...]

New baseline layout of the CERN Future Circular hadron-hadron Collider
/ Perez Segurana, Gustavo (CERN) ; Abramov, Andrey (CERN) ; Bartmann, Wolfgang (CERN) ; Benedikt, Michael (CERN) ; Bruce, Roderik (CERN) ; Giovannozzi, Massimo (CERN) ; Risselada, Thys (CERN) ; Todesco, Ezio (CERN) ; Zimmermann, Frank (CERN)
The ongoing feasibility study of the Future Circular Collider (FCC) comprises two distinct accelerators: a high-luminosity circular electron-positron collider known as FCC-ee and an energy-frontier hadron collider named FCC-hh. These two facilities are designed to take advantage of a common tunnel infrastructure. [...]

Assessing the Performance of Deep Learning Predictions for Dynamic Aperture of a Hadron Circular Particle Accelerator
/ Di Croce, Davide (EPFL, Lausanne, FSL) ; Giovannozzi, Massimo (CERN) ; Montanari, Carlo Emilio (Manchester U.) ; Pieloni, Tatiana (EPFL, Lausanne, FSL) ; Redaelli, Stefano (CERN) ; Van der Veken, Frederik F (CERN)
Understanding the concept of dynamic aperture provides essential insights into nonlinear beam dynamics, beam losses, and the beam lifetime in circular particle accelerators. This comprehension is crucial for the functioning of modern hadron synchrotrons like the CERN Large Hadron Collider and the planning of future ones such as the Future Circular Collider. [...]

Shower simulations for the CERN proton synchrotron internal dump and possible shielding options
/ Niang, Samuel (CERN) ; Huschauer, Alexander (CERN) ; Esposito, Luigi Salvatore (CERN) ; Giovannozzi, Massimo (CERN) ; Pugnat, Thomas (CERN)
During the Long Shutdown 2, the two internal dumps were replaced and successfully integrated into the CERN Proton Synchrotron operation to withstand the intense and bright beams for the High-Luminosity LHC. They function as safety devices, designed to swiftly intersect the beam’s trajectory and effectively stop the beam over multiple turns. [...]

Sorting strategies for the new superconducting magnets for the CERN HL-LHC
/ Pugnat, Thomas (CERN) ; Wegscheider, Andreas (CERN) ; Todesco, Ezio (CERN) ; Giovannozzi, Massimo (CERN) ; Tomas, Rogelio (CERN)
In a circular collider, precise control of the linear optics in the vicinity of the interaction points plays a crucial role in ensuring optimal operational performance and satisfying the machine protection constraints. Superconducting magnets are affected by unavoidable field errors that impact machine performance, and mitigation strategies are usually put in place to improve the situation. [...]
