Chapter 30: Crystal Collimation of Heavy-Ion Beams / Redaelli, S (CERN) ; Bruce, R (CERN) ; D’Andrea, M (CERN) ; Mirarchi, D (CERN) ; Rossi, R (CERN)
Crystal collimation is an advanced technique where a silicon crystal, only a few millimeters long and bent to a curvature of about 50 μみゅーrad, coherently deflects the beam halo onto a collimator absorber. This technique can improve beam collimation in the HL-LHC. [...]

Expanding the CERN ion injector chain capabilities: new beam dynamics simulation tools for future ion species / Waagaard, Elias Walter (EPFL - Ecole Polytechnique Federale Lausanne (CH)) ; Alemany Fernandez, Reyes (CERN) ; Bartosik, Hannes (CERN) ; Bruce, Roderik (CERN) ; Soubelet, Felix (CERN)
The present ion physics program in the CERN accelerator complex is mainly based on lead (208Pb82+) ion beams. Lighter ions have been considered both by the ALICE3 detector upgrade proposal at the Large Hadron Collider (LHC) -- as a potential way to achieve higher integrated nucleon-nucleon luminosity compared to the present Pb beams -- and also by the Super Proton Synchrotron (SPS) fixed-target experiment NA61/SHINE [...]

High intensity beam dynamics assessment and challenges for HL-LHC / Rumolo, G (CERN) ; Salvant, B (CERN) ; Mounet, N (CERN) ; Tomás, R (CERN) ; Bartosik, H (CERN) ; Baudrenghien, P (CERN) ; Bruce, R (CERN) ; Buffat, X (CERN) ; Calaga, R (CERN) ; De Maria, R (CERN) et al.
The High Luminosity (HL-LHC) project aims to increase the integrated luminosity of CERN’s Large Hadron Collider (LHC) by an order of magnitude compared to its initial design. This requires a large increase in bunch intensity and beam brightness compared to the first LHC runs, and hence poses serious collective-effects challenges, related in particular to electron cloud, instabilities from beam-coupling impedance, and beam-beam effects.

Revised Collimation Configuration for the Updated FCC-hh Layout / Abramov, Andrey (CERN) ; Bruce, Roderik (CERN) ; Giovannozzi, Massimo (CERN) ; Pérez Segurana, Gustavo (CERN) ; Redaelli, Stefano (CERN) ; Risselada, Thys (CERN)
The collimation system for the hadron Future Circular Collider (FCC-hh) must handle proton beams with an unprecedented nominal beam energy and stored beam energy in excess of 8 GJ, and protect the superconducting magnets and other sensitive equipment while ensuring a high operational efficiency. The recent development of the 16-dipole lattice baseline for the FCC-hh, and the associated layout changes, has necessitated an adaptation of the collimation system. [...]

Performance of the Ion Chain at the CERN Injector Complex and Transmission Studies During the 2023 Slip Stacking Commissioning / Slupecki, Maciej (CERN) ; Albright, Simon (CERN) ; Alemany-Fernández, Reyes (CERN) ; Angoletta, Maria Elena (CERN) ; Argyropoulos, Theodoros (CERN) ; Bartosik, Hannes (CERN) ; Baudrenghien, Philippe (CERN) ; Bellodi, Giulia (CERN) ; Bozzolan, Michele (CERN) ; Bruce, Roderik (CERN) et al.
The 2023 run has been decisive for the LHC Ion Injector Complex. It demonstrated the capability of producing full trains of momentum slip stacked lead ions in the SPS. [...]

Mitigating Collimation Impedance and Improving Halo Cleaning with New Optics and Settings Strategy of the HL-LHC Betatron Collimation System / Lindström, Bjorn (CERN) ; Bruce, Roderik (CERN) ; Buffat, Xavier (CERN) ; De Maria, Riccardo (CERN) ; Giacomel, Lorenzo (CERN) ; Hermes, Pascal (CERN) ; Mirarchi, Daniele (CERN) ; Mounet, Nicolas (CERN) ; Persson, Tobias (CERN) ; Redaelli, Stefano (CERN) et al.
With High Luminosity Large Hadron Collider (HL-LHC) beam intensities, there are concerns that the beam losses in the dispersion suppressors around the betatron cleaning insertion might exceed the quench limits. Furthermore, to maximize the beam lifetime it is important to reduce the impedance as much as possible. [...]

Simulations and Measurements of Betatron and Off-momentum Cleaning Performance in the Energy Ramp at the LHC / Triantafyllou, Natalia (CERN) ; Bruce, Roderik (CERN) ; D'Andrea, Marco (CERN) ; Dewhurst, Kay (CERN) ; Lindström, Bjorn (CERN) ; Mirarchi, Daniele (CERN) ; Redaelli, Stefano (CERN) ; Van der Veken, Frederik (CERN)
The Large Hadron Collider (LHC) is equipped with a multistage collimation system that protects the machine against unavoidable beam losses at large betatron and energy offsets at all stages of operation. Dedicated validations and an understanding in simulations of the collimation performance are crucial for the energy ramp from 450 GeV to 6.8 TeV because complex changes of optics and orbit take place in this phase.
