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. [...]

Design and Fabrication of a Canted-Cosine-Theta Double Aperture Orbit Corrector Dipole for the LHC
/ Pepitone, K (Uppsala U.) ; Kirby, G (CERN) ; Olvegård, M (Uppsala U.) ; Ahl, A (Scanditronix Instrument, Uppsala) ; Almström, M (Linnaeus U.) ; Dugic, I (Linnaeus U.) ; Emilsson, F (AMACC, Uppsala) ; Haralanova, V (Linnaeus U.) ; Johansson, M (Unlisted, SE) ; Karlsson, G (Linnaeus U.) et al.
A prototype CCT dipole magnet developed by a collaboration between Swedish universities, Swedish industry and CERN will be tested at Uppsala University. This 1 m long double-aperture magnet can provide a field strength of 3.3 T at 85 A in a 70 mm aperture with an integrated field of 2.8 Tm. [...]

First Prototype of the Long Orbit Nested Corrector for HL-LHC
/ Toral, F (Madrid, CIEMAT ; Madrid, Escuela Tec. Sup. Ing. Ind.) ; Alcázar, C (Madrid, CIEMAT) ; Domínguez, M (Madrid, CIEMAT) ; Durán, O (Madrid, CIEMAT) ; Estévez, A (Madrid, CIEMAT) ; García-Matos, J A (Madrid, CIEMAT ; GIFT, Spain) ; García-Tabarés, L (Madrid, CIEMAT) ; González, L A (Madrid, CIEMAT) ; Gómez, P (Madrid, CIEMAT) ; Jiménez, J (Madrid, CIEMAT) et al.
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. [...]

Long term stability studies in the presence of crab cavities and high order multipoles in the CERN super proton synchrotron and high luminosity large hadron collider
/ Alekou, A (CERN ; Manchester U.) ; Appleby, R B (Manchester U.) ; Cruz-Alaniz, E (CERN ; U. Liverpool (main)) ; Bartosik, H (CERN) ; Carlà, M (CERN) ; Kostoglou, S (CERN) ; Papaphilippou, Y (CERN)
In 2018 the world’s first Crab Cavity (CC) experiments with protons were successfully performed, aiming to study the CC effect on a proton beam and evaluate the engineering challenges. Before the commencement of these experiments, the impact of the CCs and their multipoles on the long term particle stability of the SPS was studied using dynamic aperture simulations. [...]
