Assembly and Test Results of the RMM1a,b Magnet, a CERN Technology Demonstrator Towards Nb3Sn Ultimate Performance
/ Gautheron, Emma (CERN) ; Bordini, Bernardo (CERN) ; Campagna, Guillaume (CERN) ; Felice, Hélène (CERN) ; Fleiter, Jerome (CERN) ; Guinchard, Michael (CERN) ; Izquierdo Bermudez, Susana (CERN) ; Mugnier, Sylvain (CERN) ; Perez, Juan Carlos (CERN) ; Petrone, Carlo (CERN) et al.
As part of the High Field Magnet technology development carried out at CERN, demonstrators are under construction to explore the full potential of Nb 3 Sn. The Racetrack Model Magnet (RMM) is one of them, building upon the successful Enhanced Racetrack Model Coil (eRMC) eRMC1a magnet which reached 16.5 T peak field or 16.3 T bore field at 1.9 K. [...]

Experience on Series Production of the HL-LHC Superferric High Order Corrector Magnets
/ Statera, M (Milan U.) ; Prioli, M (Milan U.) ; Broggi, F (Milan U.) ; De Matteis, E (Milan U.) ; Imeri, L (Milan U.) ; Leone, A (Milan U.) ; Mariotto, S (Milan U. ; INFN, Milan) ; Paccalini, A (Milan U.) ; Pasini, A (Milan U.) ; Pedrini, D (Milan U.) et al.
INFN has developed at the LASA lab (Milano, Italy) the High Order (HO) corrector magnets for the High Luminosity-LHC (HL-LHC) project, which will equip the new interaction regions. All the HO correctors, from skew quadrupole to dodecapole, are based on a novel superferric design, never used so far in high energy colliders, which allows a relatively simple, modular, and easy way to construct a magnet. [...]

Operational performance of crystal collimation with 6.37 $Z$ TeV Pb ion beams at the LHC
/ D'Andrea, M (CERN) ; Aberle, O (CERN) ; Bruce, R (CERN) ; Butcher, M (CERN) ; Di Castro, M (CERN) ; Cai, R (CERN) ; Lamas, I (CERN) ; Masi, A (CERN) ; Mirarchi, D (CERN) ; Redaelli, S (CERN) et al.
The concept of crystal collimation relies on the use of bent crystals to coherently deflect positively charged particles with suitable impact conditions by trapping them in the potential well generated by adjacent crystalline planes. The resulting deflection is much higher than what can be achieved by multiple scattering on amorphous materials. [...]

Thermal and supply voltage analysis of optimized ring oscillator for pixel detector readout chip
/ Istaitia, Omar (An Najah Natl. U.) ; Bassalat, Ahmed (An Najah Natl. U.) ; Abualrob, Hadil (An Najah Natl. U.) ; Lounis, Abdenour (IJCLab, Orsay) ; Khwaira, Yahya A R (IJCLab, Orsay) ; Slimani-Cherif, Ali (IJCLab, Orsay) ; Cohen-Solal, Maurice (IJCLab, Orsay)
This paper provides a specific study of the upgrade of the ATLAS pixel detector
in preparation for the upgrade of the Large Hadron Collider (LHC). The upgrade to High Luminosity-LHC (HL-LHC) is expected to start after the long shutdown in 2025-2027. [...]

Development and Qualification of High Current Splices and Electrical Connections for the HL-LHC Magnets
/ Principe, R (CERN) ; Izquierdo-Bermudez, S (CERN) ; Milanese, A (CERN) ; Prin, H (CERN) ; Sgobba, S (CERN) ; Todesco, E (CERN)
The continuity of the 18, 13, and 2 kA circuits of the HL-LHC magnets heavily relies on splices and electrical connections, to which it is worth devoting a special attention from the early phases. This spans the design of the splice or connection itself, together with the tooling and related procedure, so that the execution can reliably yield high quality results. [...]

Field Quality Analysis of the Separation-Recombination Dipole MBRD for the High-Luminosity Upgrade of LHC
/ Pampaloni, A (INFN, Genoa) ; Bersani, A (INFN, Genoa) ; Bracco, M (INFN, Genoa ; Genoa U.) ; Caiffi, B (INFN, Genoa) ; Farinon, S (INFN, Genoa) ; Fiscarelli, L (CERN) ; Foussat, A (CERN) ; Gagno, A (INFN, Genoa ; Genoa U.) ; Levi, F (INFN, Genoa) ; Ninet, G (CERN) et al.
The Main Bending Recombination Dipole (MBRD), or D2, is one of the magnets foreseen by the High-Luminosity upgrade of the Large Hadron Collider (LHC). D2 features a double aperture, Nb-Ti, cos $\theta$dipole, with a central field of 4.5 T for a length of 7.78 m, hence with an integrated magnetic field of 35 T$\cdot$m, in a 105 mm bore. [...]

Irradiation Induced Aging of Epoxy Resins for Impregnation of Superconducting Magnet Coils
/ Parragh, D M (CERN) ; Scheuerlein, C (CERN) ; Piccin, R (CERN) ; Ravotti, F (CERN) ; Pezzullo, G (CERN) ; Ternova, D (CERN) ; Taborelli, M (CERN) ; Lehner, M (Vienna, Tech. U., Atominst.) ; Eisterer, M (Vienna, Tech. U., Atominst.)
Understanding the effect of radiation on the functional properties of epoxy resins is crucial for their application in future particle accelerators like the Future Circular Collider (FCC). We compare the irradiation induced aging rates of six epoxy resin systems that can be used for the vacuum impregnation of magnet coils. [...]
