First operational experience with data-driven hysteresis compensation for the main dipole magnets of the CERN SPS
/ Lu, Anton (CERN ; Vienna, Tech. U.) ; Kain, Verena (CERN) ; Petrone, Carlo (CERN) ; Di Capua, Vincenzo (CERN) ; Schenk, Michael (CERN) ; Zannini, Carlo (CERN)
Magnetic hysteresis, eddy currents, and manufacturing imperfections pose significant challenges for beam operation in multi-cycling synchrotrons. Addressing the dynamic dependency of magnetic fields on cycling history is a current limitation for control room tools using existing models. [...]

Enhancing CERN-SPS slow extraction efficiency: meta Bayesian optimisation in crystal shadowing
/ Velotti, Francesco (CERN) ; Matheson, Eloise (CERN) ; Esposito, Luigi Salvatore (CERN) ; Fraser, Matthew (CERN) ; Solis Paiva, Santiago (CERN) ; Kain, Verena (CERN)
The Super Proton Synchrotron at CERN serves the fixed-target experiments of the North Area, providing protons and ions via slow extraction, and employs the crystal shadowing technique to significantly minimize losses. Over the past three operational years, the use of a crystal, positioned upstream of the electrostatic septum to shadow its blade, has allowed to achieve a 25% reduction in losses. [...]

Gantry design using achromatic scaling fixed-field magnets
/ Tesse, Robin (Brussels U.) ; Hernalsteens, Cédric (CERN) ; Ramoisiaux, Eliott (Brussels U.) ; Gnacadja, Eustache (Brussels U.) ; Vanwelde, Marion (Brussels U.) ; Pauly, Nicolas (Brussels U.)
Proton therapy provides significant advantages over classic radiotherapy for specific cancerous diseases, notably by limiting the delivered dose to organs at risk (OARs). Novel treatment modalities such as flash and arc therapy require changing the energy delivered at the isocenter while providing a high dose rate. [...]

A public data service for the Beam Interlock Systems at CERN - current status and future plans
/ Garnier, Jean-Christophe (CERN) ; Barth, Jonas (CERN) ; Galilée, Marc-Antoine (CERN) ; Wollmann, Daniel (CERN) ; Buszydlik, Aleksander (CERN) ; Skarhed, Tobias (CERN)
The Beam Interlock System (BIS) is the backbone of the machine protection system in CERN’s accelerator chain, ensuring that the beams are safely transported through the injector chain and circulated in the Large Hadron Collider. A new version of the BIS is currently under development and planned to be deployed in the SPS, LHC and the North Area experimental zone during the Long Shutdown 3 (LS3), while the recently installed BIS in LINAC4 and the PSB will remain in place. [...]

Damping ring and transfer lines of FCC-𝑒+𝑒− injector complex
/ Spampinati, Simone (Frascati) ; De Santis, Antonio (Frascati) ; Dutheil, Yann (CERN) ; Etisken, Ozgur (Kirikkale U. ; Frascati) ; Ramjiawan, Rebecca (CERN) ; Milardi, Catia (Frascati)
The Future Circular Collider project is built around two main pillars: the construction of 100 km lepton collider running at increasing energies from the Z-pole to the t-tbar threshold (FCC-ee) followed by a hadron collider in the same tunnel (FCC-hh) to explore unprecedented energy frontier.The realization of FCC-ee relies on a very challenging injector complex that should provide the highest ever realized source of positrons, which will serve the first phase of the collider operations (Z-pole). In this contribution the relevant aspects related to the damping of the high-emittance beam coming from the positron source and the transport of the damped beam within the different LINAC of the injector complex are presented and discussed..

Optimization of mechanical robustness in the booster injection bumpers
/ Lackner, Friedrich (CERN) ; Atanasov, Miroslav (CERN) ; Balhan, Bruno (CERN) ; Baud, Cedric (CERN) ; Borburgh, Jan (CERN) ; M Walraven (Inholland U. Appl. Sci., Alkmaar)
During the Long Shutdown 2 (LS2) at CERN, the new Linac4 (L4) accelerator has been successfully connected to the PS Booster (PSB) to inject 160 MeV H− beam into the 4 superposed PSB rings. The horizontal displacement of the circulating beam during injection relies on 4 pulsed dipole magnets. [...]
