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. [...]

Numerical Assessment of the Inhomogeneous Temperature Field and the Quality of Heat Extraction of Nb3Sn Impregnated Magnets for the High Luminosity Upgrade of the LHC / de Sousa, Patricia Borges (CERN) ; Puthran, Kirtana (CERN ; KIT, Karlsruhe) ; Sabaté-Gilarte, Marta (CERN) ; Cerutti, Francesco (CERN) ; Izquierdo Bermudez, Susana (CERN) ; Todesco, Ezio (CERN) ; van Weelderen, Rob (CERN)
The High Luminosity upgrade of the Large Hadron Collider (HL-LHC) at CERN foresees the installation of Nb3Sn-based quadrupole magnets at selected interaction points of the accelerator. The precise knowledge of each magnet's thermal characteristics and heat extraction performance in response to power depositions during both nominal and ultimate conditions is essential in determining safe operating margins.

Protection Scheme Effectiveness Study for the High-Luminosity LHC MBRD Magnet / Caiffi, Barbara (INFN, Genoa) ; Bender, Lennard (Hochschule, Eng. Econ., Karlsruhe) ; Bersani, Andrea (INFN, Genoa) ; Farinon, Stefania (INFN, Genoa) ; Foussat, Arnaud (CERN) ; Levi, Filippo (INFN, Genoa) ; Mangiarotti, Franco (CERN) ; Musenich, Riccardo (INFN, Genoa) ; Novelli, Daniel (INFN, Genoa) ; Pampaloni, Alessandra (INFN, Genoa) et al.
The MBRD (Main Bending Recombination Dipole, or D2) is one of the magnets in the interaction region of the LHC that needs to be replaced in order to fulfill the requirements of the High-Luminosity upgrade. The magnetic field must be increased up to 4.5 T in an aperture with a diameter of 105 mm and a total length of about 8 m, to reach the target integrated field of 35 T$\cdot$m. [...]

2.5-m-long nested orbit correctors (so-called MCBXFA) are necessary for the upgrade of LHC, in the framework of HL-LHC project. These magnets provide 2.1 T in vertical and horizontal direction and they share the same cross-section of their shorter version MCBXFB, for which two prototypes and the first two series magnets have been manufactured and tested.
