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. [...]

Effect of transverse compressive stress applied at room temperature on Nb$_{3}$Sn Rutherford cables / Lenoir, Gilles (CERN) ; Puthran, Kirtana (CERN ; KIT, Karlsruhe, IAP) ; Barth, Christian (CERN) ; Fleiter, Jérôme (CERN) ; Ballarino, Amalia (CERN)
The accelerator magnets for the high luminosity upgrade of the large Hadron collider use Nb$_{3}$Sn conductor to achieve the required in-field performance. To sustain the Lorentz forces during operation, a pre-compression is applied to the coils during the fabrication of the magnet. [...]

In-situ radiological classification and characterization methodology of activated cables in particle accelerators / Dyrcz, Patrycja (CERN) ; Infantino, Angelo (CERN) ; Menaa, Nabil (CERN) ; El-Idrissi, Safouane (CERN) ; Tromel, Christophe (CERN) ; Vincke, Heinz (CERN)
The estimation of induced radioactivity and radiological classification of activated material is necessary throughout the life cycle of the Large Hadron Collider (LHC) accelerator. As part of the upgrade to HighLuminosity LHC (HL-LHC), radiation protection assessments need to be performed in order to estimate the radiological hazard during the dismantling activities of the LHC cables.

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. [...]

Overview of the ATLAS HL-LHC upgrade programme / Lanni, Francesco (CERN)
ATLAS is planning to upgrade most of its detector systems to prepare for the operations during the HL-LHC era. A tenfold increase of the luminosity delivered to the experiment by the accelerator complex, compared to the integrated luminosity of the first three LHC runs, will impose significant challenges in terms of rates and radiation resistance.
