Development of a Closed Helium Circuit Cooled Demonstrator Magnet for Carbon Ion Therapy / Geiger, K (CERN) ; de Sousa, P Borges (CERN) ; Ceruti, G (CERN) ; Dasa, L (CERN) ; Haziot, A (CERN) ; Karppinen, M (CERN) ; Koettig, T (CERN) ; Viguri, I Perez de Lazarraga (CERN) ; Timmins, M (CERN)
Closed-circuit cooling of superconducting magnets unlocks new possibilities for advanced accelerator designs and applications. In hadron therapy, it has clear potential for compact rotating gantries, while for future accelerator cryogenic systems it could significantly reduce helium inventories. [...]

First comments on a descoped/staged FCC-ee / Blondel, Alain (LPNHE, Paris) ; Grojean, Christophe (DESY ; Humboldt U., Berlin) ; Janot, Patrick (CERN) ; Wilkinson, Guy (Oxford U.)
In response to its remit, the European Strategy Group (ESG) recommended the electron-positron Future Circular Collider (FCC-ee) as the preferred option for the next flagship collider at CERN; and a descoped FCC-ee as the preferred alternative option (with reduced synchrotron radiation (SR) power, without a run at the $\rm t \bar t$ threshold, and with only two interaction regions) in the event that the preferred option turns out not to be feasible.

HTS Superferric Combined Function Magnet for the FCC-ee Project / Busatto, Simone (U. Rome La Sapienza (main) ; INFN, Milan) ; Mariotto, Samuele (U. Milan (main) ; INFN, Milan) ; Rossi, Lucio (U. Milan (main) ; INFN, Milan)
Energy consumption represents an increasing critical challenge for particle physics research laboratories like CERN. This issue is particularly significant in large accelerator facilities, where normal conducting magnet technology plays a fundamental role in the beamline design. [...]

Development and Testing of the First REBCO Racetrack Model Coils at CERN / Baskys, Algirdas (CERN) ; Ballarino, Amalia (CERN) ; Barth, Christian (CERN) ; Fiscarelli, Lucio (CERN) ; Gal, Norbert (CERN) ; Mangiarotti, Franco J (CERN) ; Mazet, Jacky (CERN) ; Perini, Diego (CERN) ; Saba, Aisha (CERN)
One of the goals of the High Field Magnet (HFM) Program at CERN is to explore High-Temperature Superconduct- ing (HTS) magnet technology for accelerator applications that go beyond the limits of low-temperature superconductors such as Nb3Sn. This offers a pathway for the development of higher energy and more sustainable particle accelerators operating at temperatures above 1.9 K or even 4.5 K. [...]

Assembly of the Nb-Sn MQXFB Quadrupole for HL-LHC / Quassolo, Penelope Matilde (CERN) ; Ferracin, Paolo (LBNL, Berkeley) ; Ferradas Troitino, Jose (CERN) ; Izquierdo Bermudez, Susana (CERN) ; Lusa, Nicholas (CERN) ; Mugnier, Sylvain (CERN) ; Triquet, Stephane (CERN)
The High-Luminosity LHC (HL-LHC) project aims to upgrade the existing LHC machine to increase its integrated luminosity by a factor of ten. A key aspect of this upgrade is the inner triplet (or low-$\beta$) quadrupole magnets, the MQXF, which utilise Nb$_{3}$Sn superconducting magnet technology and reach a conductor peak field of 11.3 T.

Optics studies in the LHC are generally performed on low-intensity, non-colliding beams. Understanding the optics perturbation from beam-beam effects however, is of significant interest. [...]

Luminosity modeling of the LHC operation and performance projections for HL-LHC / Kostoglou, Sofia (CERN) ; Sterbini, Guido (CERN) ; Bartosik, Hannes (CERN) ; Efthymiopoulos, Ilias (CERN) ; Mounet, Nicolas (CERN) ; Tomas, Rogelio (CERN) ; De Maria, R (CERN)
The LHC luminosity model is a powerful tool for studying the evolution of beam and machine parameters during the LHC operation. The model includes important effects that are present in LHC operation such as Intra-Beam Scattering, synchrotron radiation and burn-off. [...]

Measuring single-pass dispersion in the LHC / De Souza, Vitor (LNLS, Campinas) ; Persson, Tobias (CERN) ; Tomas, Rogelio (CERN) ; Maclean, Ewen (CERN)
During the LHC Ion Run in 2023, the ALICE detector observed a high level of background that prevented efficient data taking. This background was caused by different ion species generated in the betatronic collimation region that were intercepted by the Tertiary collimator near ALICE Interaction Point. [...]

Simulations of losses from fast instabilities in the FCC-ee / Nigrelli, Giulia (CERN ; U. Rome La Sapienza (main) ; Frascati) ; Broggi, Giacomo (CERN ; Frascati ; U. Rome La Sapienza (main)) ; Boscolo, Manuela (Frascati) ; Bruce, Roderik (CERN) ; Redaelli, Stefano (CERN) ; Buffat, Xavier (CERN)
The electron-positron Future Circular Collider (FCC-ee) is a proposed high-energy lepton collider that aims to reach unprecedented luminosity and precision in the measurement of fundamental particles. To fully profit of such performance, it is crucial to keep detector backgrounds under control and operate the machine safely. [...]

Integration of the HL-LHC machine and its services within the existing LHC tunnel: Challenges and proposed approaches for the integration of a large-scale project / Nicoletti, Francesca Paola (CERN) ; Ramrekha, Darshana (CERN) ; Corso, Jean-Pierre (CERN) ; Oliveira, Joao (CERN) ; Coupard, Julie (CERN) ; Modena, Michele (CERN) ; Navarro Baeza, Miguel (CERN) ; Joannon, Nicolas (Unlisted, CH) ; Fessia, Paolo (CERN) ; Maridor, Stephane (CERN)
The High Luminosity Large Hadron Collider (HL-LHC) project is a major upgrade of the LHC presently operating at CERN, designed to enhance the performance reach in terms of integrated luminosity collected during its operational era by another order of magnitude. It involves the replacement of the entire machine and services over more than 200 meters on each side of the high luminosity experiments of ATLAS and CMS, and other modifications across the entire LHC complex.
