/ Garcia Jaimes, Cristobal Miguel (Ecole Polytechnique, Lausanne, LPAP) ; Thabuis, Adrien (CERN) ; Auchmann, Bernhard (PSI, SLS) ; Kosse, Jaap (PSI, SLS) ; van Riesen-Haupt, Léon (Ecole Polytechnique, Lausanne, LPAP) ; Koratzinos, Michael (CERN) ; Seidel, Mike (Ecole Polytechnique, Lausanne, LPAP) ; Tomas, Rogelio (CERN) ; Pieloni, Tatiana (Ecole Polytechnique, Lausanne, LPAP)
The Future Circular Collider (FCC-ee) is designed to explore the Z and W± bosons, along with the Higgs boson and top quark, achieving exceptionally high luminosity. In order to minimize the energy lost per turn due to Synchrotron Radiation (SR) we explore the use of Nested Magnets (NMs) into the arcs cell. [...]

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.

Radiation shielding studies for superconducting magnets in multi-TeV muon colliders
/ Lechner, Anton (CERN) ; Amorim, David (CERN) ; Bottura, L (CERN) ; de Sousa, P Borges (CERN) ; Caiffi, B (INFN, Genoa) ; Calzolari, D (CERN) ; Carli, C (CERN) ; Ferreira Somoza, J (CERN) ; Frasca, A (CERN) ; Lerner, G (CERN) et al.
Circular muon colliders provide the potential to explore center-of-mass energies at the multi-TeV scale within a relatively compact footprint. Because of the short muon lifetime, only a small fraction of stored beam particles will contribute to the physics output, while most of the muons will decay in the collider ring. [...]

Superconducting magnets technology for a European heavy ion gantry
/ Prioli, Marco (LASA, Segrate) ; Santini, Carlo (LASA, Segrate) ; Barna, Daniel (Wigner RCP, Budapest) ; Gusvitskii, Todor (Rome U.) ; Perini, Diego (CERN) ; Bianchi, E (INFN, Genoa) ; Felcini, Enrico (CNAO, Milan) ; De Matteis, Ernesto (LASA, Segrate) ; Toral, Fernando (Madrid, CIEMAT) ; Levi, Filippo (INFN, Genoa) et al.
Various initiatives in Europe have been launched to study superconducting magnets for a rotatable gantry suitable to deliver up to 430 MeV/u carbon ions for hadron therapy. Different technologies and layouts are being considered: the baseline solution is developed within the EuroSIG collaboration and consists of a strongly curved cos-$\theta$ dipole based on the classical NbTi superconductor.

Mechanical design of the 12 T superconducting dipole. An accelerator-fit, Nb₃Sn double aperture magnet
/ Masci, Marco (CERN) ; Perini, Diego (CERN) ; Baudin, Lucie (CERN)
In the context of the High Field Magnet programme, the 12 T Nb3Sn activity aims to design and manufacture a 2-meter-long, 12 T, cosθ, double aperture dipole. To reach magnetic fields higher than 10 T in accelerator magnets, brittle epoxy-impregnated Nb3Sn Rutherford cables are employed, which makes it difficult to predict the coil's mechanical limit and, in extenso, the magnet's performance.

Transient finite-element simulations of fast-ramping muon-collider magnets

Conceptual studies for a muon collider identify fast-ramping magnets as a major design challenge. Rise rates of more than 1 T/ms are attainable with normal-conducting magnets, incorporating iron yokes to make sure that stored magnetic energies and inductances stay below reasonable thresholds. [...]

Upgrade of the PS booster-to-ISOLDE beam transfer line to facilitate an increase in proton driver energy

Following the successful completion of the LHC Injectors Upgrade (LIU) project, since 2021 the Proton Synchrotron (PS) Booster has served the LHC injector chain with protons at an increased kinetic energy of 2 GeV. An upgrade of the ISOLDE (Isotope Separator On-Line DEvice) facility has long been considered to produce radioactive ion beams with a higher energy proton driver beam. [...]

Study of the corrector systems for the new lattice of the CERN hadron-hadron Future Circular Collider
/ Perez-Segurana, Gustavo (CERN) ; Todesco, Ezio (CERN) ; Giovannozzi, Massimo (CERN)
A new layout for the energy-frontier hadron collider (FCC-hh) under study at CERN has been designed, following the constraints imposed by the outcome of recent tunnel placement studies. The new lattice and the need to maximize the dipole filling factor triggered a deep revision of the corrector systems located in the regular arcs, such as orbit, tune, linear coupling, and chromaticity correctors.

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. [...]

Sextupole RDTs in the LHC at injection and in the ramp
/ Horney, S J (CERN ; Oxford U.) ; Maclean, E (CERN) ; Burrows, P (Oxford U.) ; Carlier, F (CERN) ; Dilly, J (CERN) ; Deniau, L (CERN) ; Ferrentino, V (CERN) ; Fol, E (CERN) ; Hofer, M (CERN) ; Keintzel, J (CERN) et al.
During 2023, examination of the action dependence of sextupolar resonance driving terms (RDT) in the LHC at injection, as measured with an AC-dipole, demonstrated that a robust measurement of the RDTs could still be achieved even with very small amplitude kicks, typically used for linear optics studies. Consequently, analysis of optics measurements from 2022 and 2023 during the LHC energy ramp allowed a first measurement of the sextupole resonance evolution. [...]
