Bridging physical and digital worlds with a mechanical digital twin / Sacristan De Frutos, Oscar (speaker) (CERN)
The Future Circular Collider (FCC) demands extremely stringent vibrational stability and precise alignment of its arc cell components. This workshop contribution focuses on the development of a digital twin for the FCC arc cell mockup to address these critical mechanical challenges. [...]

Finite Element Analysis and Experimental Validation of Low-Pressure Beam Windows for XCET Detectors at CERN / Buesa Orgaz, Jan (CERN) ; Brugger, Markus (CERN) ; Romagnoli, Giulia (CERN) ; Sacristan De Frutos, Oscar (CERN) ; Sanchez Galan, Francisco (CERN)
In the framework of the renovation and consolidation of experimental areas at CERN, a low-pressure design beam superimposed windows (250 µm Mylar and 150 µm polyethylene) for the Threshold Cherenkov counters (XCET) has been modelled and verified for its implementation. The XCET is a detector used to count the number of selected charged particles in the beam by adjusting the pressure that leads to the emission of Cherenkov photons only above certain pressure threshold. [...]

Mechanical Behavior of the Shielded HL-LHC Beam Screen during a Magnet Quench / Morrone, Marco (CERN) ; Garion, Cedric (CERN) ; Chiggiato, Paolo (CERN) ; Sacristan De Frutos, Oscar ; Guinchard, Michael (CERN) ; Fiscarelli, Lucio (CERN)
In the framework of the High-Luminosity Large Hadron Collider (HL-LHC) project, larger and shielded beam screens will be installed in the beam pipe of the superconducting magnets of the insertion next to the ATLAS and CMS detectors. The beam screen is a complex assembly that guarantees the vacuum requirements while shielding the magnet cold mass from the induced heat loads. [...]

New Methodology to Derive the Mechanical Behavior of Epoxy-Impregnated Nb$_3$Sn Cables / Fichera, Claudio (CERN) ; Bertarelli, Alessandro (CERN) ; Ferracin, Paolo (CERN) ; Guinchard, Michael (CERN) ; Sacristan de Frutos, Oscar (CERN) ; Vallone, Giorgio (CERN)
The Nb3Sn technology plays a crucial role in developing high-field superconducting magnets. The new-generation Nb3Sn cable greatly contributes to bring the magnetic field produced by the superconducting dipole magnets to the 16 T level; nevertheless, its mechanical properties are largely variable, making it difficult to predict the mechanical behavior of the magnet structure.

Design Optimization and Assessment of Fabrication of ITER Central Solenoid Twin Box Joints / Santillana, Ignacio Aviles (CERN) ; Guinchard, Michael (CERN) ; Lourenço, Sandra Sophie (CERN) ; Motschmann, Fritz (CERN) ; Sacristan de Frutos, Oscar (CERN) ; Sgobba, Stefano (CERN) ; Bruton, Andrew (BIAM, St Paul lez Durance) ; Gaxiola, Enrique (BIAM, St Paul lez Durance) ; Libeyre, Paul (BIAM, St Paul lez Durance) ; Schild, Thierry (BIAM, St Paul lez Durance) et al.
The ITER Central Solenoid (CS) will be one of the world's largest and most powerful pulsed superconducting electromagnet ever built; at an approximate weight of 1300 tons and a total height of 18 m consisting of a stack of six electrically independent 4.1 m diameter modules. In order to electrically connect the CS with the feeder busbars, 12 twin box joints are used to assure an efficient high current transfer while avoiding excessive AC losses. [...]

10 kA Joints for HTS Roebel Cables / Murtomaki, Jaakko Samuel (CERN) ; Kirby, Glyn (CERN) ; van Nugteren, Jeroen (CERN) ; Contat, Pierre-Antoine (CERN) ; Sacristan-de-Frutos, Oscar (CERN) ; Fleiter, Jerome (CERN) ; Pincot, Francois-Olivier (CERN) ; de Rijk, Gijs (CERN) ; Rossi, Lucio (CERN) ; Ruuskanen, Janne (Tampere U. of Tech.) et al.
Future high temperature superconductor (HTS) high field magnets using multitape HTS cables need 10-kA low-resistance connections. The connections are needed between the poles of the magnets and at the terminals in a wide-operating temperature range, from 1.9-85 K. [...]

Dynamic Testing and Characterization of Advanced Materials in a New Experiment at CERN HiRadMat Facility / Bertarelli, Alessandro (CERN) ; Accettura, Carlotta (CERN ; Milan Polytechnic) ; Berthomé, Emmanuel (CERN) ; Bianchi, Laura (CERN) ; Bolz, Philipp (Darmstadt, GSI) ; Carra, Federico (CERN) ; Fichera, Claudio (CERN) ; Frankl, Matthias (CERN) ; Furness, Thomas (Huddersfield U.) ; Gobbi, Giorgia (CERN) et al.
An innovative and comprehensive experiment (named “Multimat”) was successfully carried out at CERN HiRadMat facility on 18 different materials relevant for Collimators and Beam Intercepting Devices. Material samples, tested under high intensity proton pulses of 440 GeV/c, exceeding the energy density expected in HL-LHC, ranged from very light carbon foams to tungsten heavy alloys, including novel composites as graphite/carbides and metal/diamond without and with thin-film coatings.
