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. [...]

Gamma Factory for CERN initiative - progress report / Dutheil, Yann (CERN) ; Abramov, Andrey (Royal Holloway, U. of London) ; Alden, Siobhan (Royal Holloway, U. of London) ; Alemany Fernandez, Reyes (CERN) ; Antsiferov, Pavel (Troitsk, IZMIRAN) ; Apyan, Armen (NAS Armenia, Yerevan) ; Bartosik, Hannes (CERN) ; Bessonov, Evgeny (Lebedev Inst.) ; Biancacci, Nicolo (CERN) ; Bieron, Jacek (Jagiellonian U.) et al.
The Gamma Factory (GF) initiative proposes to use partially stripped ion (PSI) beams as drivers of a new type of high-intensity and high-energy (0.1–400 MeV) photon source. As part of the ongoing Physics Beyond Collider studies, initial beam tests were carried out in 2017 and 2018 at the SPS and LHC with partially stripped xenon and lead beams [...]

Quench Protection Studies for the High Luminosity LHC Nb$_3$Sn Quadrupole Magnets / Ravaioli, Emmanuele (CERN) ; Ambrosio, Giorgio (Fermilab) ; Bajas, Hugues (CERN) ; Duda, Michal (PSI, Villigen ; CERN) ; Ferracin, Paolo (LBNL, Berkeley) ; Ferradas Troitino, Jose (CERN) ; Izquierdo Bermudez, Susana (CERN) ; Mangiarotti, Franco (CERN) ; Marinozzi, Vittorio (Fermilab) ; Mentink, Matthias (CERN) et al.
Achieving the targets of the High Luminosity LHC project requires the installation of new inner triplet magnet circuits for the final focusing of the particle beams on each side of the two main interaction points. Each of the four circuits will include six 150 mm aperture, 132.2 T/m gradient, Nb$_3$Sn quadrupole magnets to be installed in the LHC tunnel. [...]

Characterization of the beam scraping system of the CERN Super Proton Synchrotron / Mereghetti, Alessio (CERN) ; Cerutti, Francesco (CERN) ; Appleby, Robert B (Cockcroft Inst. Accel. Sci. Tech. ; Manchester U.)
The Super Proton Synchrotron at CERN is equipped with a scraping system for halo cleaning at beam transfer to the Large Hadron Collider. The system is composed of movable graphite blades mechanically swept through the beam to remove tails immediately before beam transfer. [...]
