Topical issue on the intersection of low-energy nuclear structure and high-energy nuclear collisions / Duguet, T. (IRFU, Saclay ; KU Leuven, Dept. Phys. Astron.) ; Giacalone, G. (CERN ; U. Heidelberg, ITP) ; Somà, V. (IRFU, Saclay) ; Zhou, Y. (Bohr Inst.)
High-energy heavy-ion physics and low-energy nuclear structure physics have historically been disconnected fields. The hydrodynamic description of the quark-gluon plasma (QGP) requires input from nuclear structure to model the initial states of the colliding nuclei. [...]

Adaptive Hough Transform for Charged Particles Tracking at the LHC / Bold, Tomasz (AGH-UST, Cracow) ; Horodenski, Stefan (AGH-UST, Cracow) ; Libucha, Piotr (AGH-UST, Cracow)
The High-Luminosity Large Hadron Collider (HL-LHC) will significantly increase the number of simultaneous proton-proton interactions per bunch crossing, making efficient track reconstruction increasingly challenging. This study explores the Adaptive Hough Transform (AHT) as an alternative approach to track finding, optimizing the balance between computational efficiency and memory usage. [...]

Design Strategies for Beam Impedance Reduction of Kicker Magnets in Particle Accelerators / Trubacova, Pavlina (CERN) ; Barnes, Mike (CERN) ; Coralejo Feliciano, Luis Miguel (CERN) ; Zumel, Miguel Diaz (CERN) ; Ducimetiere, Laurent (CERN) ; Favia, Giorgia (CERN) ; Kramer, Thomas (CERN) ; Namora, Vasco (CERN) ; Neroni, Michela (CERN) ; Standen, Dylan (CERN) et al.
In high-energy particle accelerators, kicker magnets are essential for injecting and extracting particle beams using fast-pulsed magnetic fields. A key challenge in their design is minimizing beam coupling impedance to maintain beam stability and reduce beam induced power losses while preserving the fast rise and fall times of the magnetic pulse. [...]

Real-time pattern recognition with FPGA at LHCb, an O($n$) complexity architecture / Lazzari, Federico (U. Pisa (main) ; INFN, Pisa) ; Contu, Andrea (INFN, Cagliari) ; Fantechi, Riccardo (INFN, Pisa) ; He, Jibo (UCAS, Beijing) ; Jashal, Brij Kishor (Rutherford Appleton Laboratory) ; Martinelli, Maurizio (Milan Bicocca U.

Valencia (main) ; CSIC, Madrid) ; Pica, Lorenzo (INFN, Pisa ; Pisa, Scuola Normale Superiore) ; Punzi, Giovanni (U. Pisa (main) ; INFN, Pisa) et al.
The LHCb collaboration is planning an upgrade (LHCb “Upgrade- II”) to collect data during Run 5 at an instantaneous luminosity an order of magnitude larger than the current one (Run 3). LHCb relies on a complete realtime reconstruction of all collision events at LHC-Point 8, which will have to cope with both the luminosity increase and the introduction of correspondingly more granular and complex detectors.

Metal as Insulation REBCO Racetracks Coils: Development, Fabrication, and Cryogenic Testing at CEA Paris-Saclay / Lecrevisse, Thibault (IRFU, Saclay) ; Benoist, Emeric (IRFU, Saclay) ; Blondelle, Audren (IRFU, Saclay) ; Caunes, Antomne (IRFU, Saclay) ; Durochat, Matthias (IRFU, Saclay) ; Genot, Clément (IRFU, Saclay) ; Lenoir, Gilles (IRFU, Saclay) ; Maloeuvre, Bruno (IRFU, Saclay) ; Ballarino, Amalia (CERN) ; Baskys, Algirdas (CERN)
CEA-Saclay started the development of Metal-as-Insulation racetrack coils in as part of the High Field Magnet (HFM) CERN program. This winding method aims to significantly reduce the amount of High Temperature Superconductor material required to achieve relatively high magnetic induction and associated forces. [...]

RQR beam qualities measurement with the Timepix4 detector / Genetay, T (CERN ; Lausanne U.) ; Tlustos, L (CERN ; CTU, Prague) ; Campbell, M (CERN) ; Bochud, F (Lausanne U.) ; Carbonez, P (CERN ; Otago U.) ; Damet, J (Lausanne U. ; Otago U.)
This work presents, to the best of the authors’ knowledge, the first attempt at reconstructing X-ray spectra with a hybrid pixel detector for radiation protection applications in the scattered field around fluoroscopy devices. The performance of the Timepix4 detector was evaluated under reference conditions using RQR beam qualities. [...]

Updates on the Conceptual Design Study of the Magnets for the Muon Collider Storage Ring / IMCC Collaboration
The Muon Collider represents an exciting proposal for a post-LHC accelerator, capable of exploring higher-energy regions with greater power consumption efficiency compared to hadronic alternatives, while avoiding synchrotron radiation limitations inherent in electron colliders. This contribution will focus on the magnets for the Muon Collider storage ring. [...]

ROOT RNTuple implementation in Julia programming language / Ling, Jerry (Harvard U. (main)) ; Gál, Tamás (U. Erlangen-Nuremberg (main))
RNTuple is the upcoming primary data storage solution at the Large Hadron Collider (LHC) experiments and other high-energy physics (HEP) experiments going forward. Aside from many technical upgrades from the TTree object, RNTuple also is the first time .root file committed to specification.[1]In this paper we present the latest development in UnROOT.jl that enables both the reading and writing of complex table-like data structures in Julia with RN-Tuple.

A point library for the fast simulation of the LHCb calorimeter / Kholodenko, Sergei (INFN, Pisa) ; Kreps, Michal (Warwick U.) ; Mazurek, Michal (NCBJ, Warsaw) ; Rama, Matteo (INFN, Pisa)
The simulation of physics events in the LHCb experiment uses the majority of the experiment’s distributed computing resources. Most of the computing time is spent on the Geant4-based detailed detector simulation, with approximately 50% of it dedicated to the calorimeter system. [...]
