An overview of progress with the study of a structured laser beam for alignment / Niewiem, Witold Grzegorz (ETH Zurich (CH)) ; Mergelkuhl, Dirk (CERN) ; Gayde, Jean-Christophe (CERN)
The Structured Laser Beam (SLB) is a pseudo-non- diffractive optical beam characterized by the low divergence of the Inner Core (IC), down to 10 μrad, and the presence of concentric rings, with the most prominent being the Outer Ring (OR). [...]

Construction and Analysis of a Modified Nb3Sn 11 T Short Dipole Model / Cabrera, Carmen Abad (CERN) ; Perini, Diego (CERN) ; Bampton, Tavis Alexander (CERN) ; Bahmane, Oussama Id (CERN) ; Izquierdo Bermudez, Susana (CERN) ; Bourcey, Nicolas (CERN) ; Devred, Arnaud (CERN) ; Vez, Ruth Diaz (CERN) ; Garion, Cedric (CERN) ; Guinchard, Michael (CERN) et al.
The 5.2-m-long, 11 T double-aperture Nb3Sn Dipole Magnet was designed to replace some of the standard, 15-m-long 8.3 T Nb–Ti main dipole magnets in the Large Hadron Collider. After the production and test of several of 2-m-long models, the test of full-length 11 T series magnets revealed signs of performance degradation in the coil ends after a sequence of electromagnetic and thermal cycles. The possible sources for performance degradation were categorized into two groups: issues internal to the coils and issues with the coil support structure, in particular in the magnet ends. [...]

Performance of a HL-LHC Nb$_3$Sn Quadrupole Magnet in the 100–200 MPa Range of Azimuthal Stress / Mangiarotti, F J (CERN) ; Izquierdo Bermudez, S (CERN) ; Devred, A (CERN) ; Diaz Vez, R (CERN) ; Ferradas Troitino, J (CERN) ; Ferradas Troitino, S (CERN) ; Feuvrier, J (CERN) ; Guinchard, M (CERN) ; Haziot, A (CERN) ; Milanese, A (CERN) et al.
With the assembly and test results of four Nb$_\text{3}$Sn short-model quadrupoles (MQXFS) for the High Luminosity Upgrade of the CERN Large Hadron Collider (LHC), an optimum pre-load level was established for the construction of the full-length, series magnets. Successive MQXFS magnets were used as testbeds for potential changes (including pre-load fine tuning) to be implemented in the series, and to better understand the stress dependence of Nb$_\text{3}$Sn magnet performance.

Laser-Induced Quench Study of the Magneto-Thermal Stability of Nb$_3$Sn Wires / Kuczynska, J H (CERN ; Geneva U.) ; Hopkins, S C (CERN) ; Senatore, C (Geneva U.) ; Boutboul, T (CERN)
In the pursuit of developing 14+ T Nb$_3$Sn magnets for a future energy-frontier circular collider, there is a growing demand for wires with enhanced critical current density (Jc), larger diameters, and lower copper-to-non-copper ratios. These requirements pose significant challenges to maintaining magnetothermal stability of the superconducting wires. [...]

Evaluating the Electro-Magnetic Effects of Electrical Short-Circuits in a Nb-Ti Accelerator Magnet / Reynaud, V (CERN ; Polytech. Turin) ; Farinon, S (INFN, Genoa) ; Janitschke, M (CERN ; U. Rostock) ; Ravaioli, E (CERN) ; Verweij, A P (CERN) ; Willering, G (CERN) ; van Rienen, U (U. Rostock)
Electrical short-circuits in the coil winding pack of a superconducting magnet can severely impact the magnet's performance and safety during operation. Hence, finding ways to detect and assess these non-conformities is essential. [...]
