Mitigation strategies for the instabilities induced by the fundamental mode of the HL-LHC Crab Cavities
/ Giacomel, L (CERN) ; Baudrenghien, P (CERN) ; Calaga, R (CERN) ; Buffat, X (CERN) ; Mounet, N (CERN)
The transverse impedance is one of the potentially limitingeffects for the performance of the High-Luminosity Large HadronCollider (HL-LHC). In the current LHC, the impedance is dominatedby the resistive-wall contribution of the collimators at typicalbunch-spectrum frequencies, and is of broad-bandnature. [...]

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

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.

The high luminosity Large Hadron Collider project: from project to reality at CERN
/ Cantalapiedra, G Aparicio (CERN) ; Oliveira, J (CERN) ; Corso, J P (CERN) ; Fessia, P (CERN) ; Maridor, S (CERN) ; Modena, M (CERN)
The High Luminosity Large Hadron Collider (HL-LHC) project is an upgrade of the LHC aiming to increase by a factor 10 the harvested integrated luminosity foreseen early 40s. During Long Shutdown 3, scheduled to begin at the end of 2025, nearly 1.2 km of accelerator components, including a range of services spread across surface and underground facilities, will be replaced with new equipment deploying innovative key technologies.

Potential and constraints of a beam-beam wire compensator in the HL-LHC era
/ Sterbini, G (CERN) ; Bertarelli, A (CERN) ; Papaphilippou, Y (CERN) ; Poyet, A (CERN) ; Rossi, A (CERN) ; Bélanger, P (TRIUMF)
The compensation of the long-range beam-beam interactions by DC wires is currently being investigated as an option for enhancing machine performance in the framework of the High-Luminosity LHC Project. In this paper, we report and comment on the potential of wire compensation during the first HL-LHC run. [...]
