First demonstration of the use of crab cavities on hadron beams / Calaga, R (CERN) ; Alekou, A (Manchester U.) ; Antoniou, F (CERN) ; Appleby, R B (Manchester U.) ; Arnaudon, L (CERN) ; Artoos, K (CERN) ; Arduini, G (CERN) ; Baglin, V (CERN) ; Barriere, S (CERN) ; Bartosik, H (CERN) et al.
Many future particle colliders require beam crabbing to recover geometric luminosity loss from the nonzero crossing angle at the interaction point (IP). A first demonstration experiment of crabbing with hadron beams was successfully carried out with high energy protons. [...]

Injectors and in particular the positron production systems are a crucial element in linear and circular colliders. The proposed FCC-ee injector linac accelerates both electrons and positrons up to 6 GeV in order to be injected into the Pre-Booster Ring (PBR) with a high intensity of 3.5 nC per bunch for the Z running mode.

The next generation particle accelerators will need to increase by an order of magnitude the center-of-mass energy: a viable solution is a 100 TeV circular collider, temporarily called Future Circular Collider (FCC). To achieve this goal, a new generation of double aperture superconducting magnets, capable of generating a high quality, stable 16 T magnetic field in a 50 mm bore is being developed. [...]

The Falcon Dipole (Future Accelerator post-LHC Cos-theta Optimized $\rm {Nb_3Sn}$ Dipole) is a single aperture $\rm {Nb_3Sn}$cos-theta dipole short model in the framework of the Future Circular Collider (FCC) project. The Italian Institute of Nuclear Physics (INFN), in collaboration with CERN, is in charge of designing and constructing the magnet, which is a crucial step towards the construction of High Field $\rm {Nb_3Sn}$magnets suitable for a post LHC collider.

Impact of betatron collimation losses in the High-Energy Large Hadron Collider / Varasteh, M (CERN) ; Bruce, R (CERN) ; Cerutti, F (CERN) ; Crouch, M (CERN) ; Zimmermann, F (CERN)
In response to recommendations in the 2013 update of the European Strategy for Particle Physics, a conceptual design effort for an energy upgrade of the Large Hadron Collider (LHC) at CERN, the so-called high-energy LHC (HE-LHC), was launched as part of the Future Circular Collider study. The HE-LHC machine, which is meant to use 16 T magnet technologies in the existing LHC tunnel, would provide proton collisions at a center-of-mass energy of 27 TeV (∼2×LHC) with a total stored energy of 1.34 GJ (∼4×LHC) per beam.

On the mechanisms governing the critical current reduction in Nb$_{3}$Sn Rutherford cables under transverse stress / De Marzi, Gianluca (ENEA, Frascati ; CERN) ; Bordini, Bernardo (CERN) ; Baffari, Dario (CERN)
Within the framework of the HiLumi-LHC project, CERN is currently manufacturing 11 T dipole and quadrupole accelerator magnets using state-of-the-art Nb$_{3}$Sn Rutherford cables. Even higher magnetic fields are considered by the Hadron Future Circular Collider (FCC-hh) design study, which plans to develop 16 T Nb$_{3}$Sn bending dipoles. [...]
