Initial design of a proton complex for the Muon Collider
/ Johannesson, Sofia (ESS, Lund) ; Lombardi, Alessandra (CERN) ; Gorzawski, Arkadiusz (ESS, Lund) ; Kelliher, David (Rutherford Appleton Laboratory) ; Laface, Emanuele (ESS, Lund) ; Vojskovic, Isabella (ESS, Lund) ; Milas, Natalia (ESS, Lund) ; Machida, Shinji (Rutherford Appleton Laboratory) ; Gilardoni, Simone (CERN)
The proton complex is the first piece in the Muon Collider, it comprises a high power acceleration section, a compressor and a target delivery system. For the International Muon Collider Collaboration we are investigating the possibility of having a full energy 5-GeV linac followed by an accumulator and a compressor ring and finally a target delivery system.

Channeling performance of bent crystals developed at CERN
/ Rodin, Volodymyr (CERN) ; Esposito, Luigi Salvatore (CERN) ; Lechner, Anton (CERN) ; Demassieux, Quentin (CERN) ; Matheson, Eloise (CERN) ; Solis Paiva, Santiago (CERN) ; Seidenbinder, Regis (CERN) ; Aberle, Oliver (CERN) ; Perillo Marcone, Antonio (CERN) ; Calviani, Marco (CERN) et al.
Bent crystals are a mature technology used in several applications at CERN, such as the crystal-assisted collimation system for LHC ion operation and reduction of losses during the slow extraction from the SPS by shadowing the electrostatic septum. In the future, it is planned to measure electric and magnetic dipole moments of short-lived particles with a double-crystal experiment in the LHC. [...]

Hubert Curien, St. Etienne) ; Uznanski, Slawosz (CERN)
In this work, we present the radiation environment of the large hadron collider (LHC), focusing on the year 2022, the first after the Long Shutdown 2 (LS2) (2019–2021). We highlight the most prominent radiation-level changes with respect to the 2018 operation, commenting on the related Radiation Hardness Assurance implications. [...]

The LHC Injectors Upgrade (LIU) project was put in place between 2010 and 2021 to increase the intensity and brightness in the LHC injectors to match the challenging requirements of the High-Luminosity LHC (HL-LHC) project, while ensuring reliable operation of the injectors complex up to the end of the HL-LHC era (ca. 2040).

Characterization of bent crystals for beam collimation with 6.8 TeV proton beams at the LHC
/ D'Andrea, Marco (CERN) ; Aberle, Oliver (CERN) ; Abramov, Andrey (CERN) ; Bandiera, Laura (INFN, Ferrara) ; Bruce, Roderik (CERN) ; Cai, Rongrong (CERN ; EPFL-ISIC, Lausanne) ; Calviani, Marco (CERN) ; Demassieux, Quentin (CERN) ; Dewhurst, Kay Alana (CERN) ; Di Castro, Mario (CERN) et al.
The concept of crystal collimation exploits the peculiar properties of crystalline materials to deflect high-energy beam particles at angles orders of magnitude larger than what can be achieved with scattering by conventional materials used as primary collimators. This innovative technique is planned to be used to improve the collimation efficiency with heavy-ion beams at the Large Hadron Collider (LHC) and its High-Luminosity upgrade (HL-LHC). [...]

CERN Super Proton Synchrotron Radiation Environment and Related Radiation Hardness Assurance Implications
/ Biłko, Kacper (CERN ; Lab. Hubert Curien, St. Etienne) ; García Alía, Rubén (CERN) ; Di Francesca, Diego (CERN) ; Aguiar, Ygor (CERN) ; Danzeca, Salvatore (CERN) ; Gilardoni, Simone (CERN) ; Girard, Sylvain (Lab. Hubert Curien, St. Etienne) ; Esposito, Luigi Salvatore (CERN) ; Fraser, Matthew Alexander (CERN) ; Mazzola, Giuseppe (CERN) et al.
The super proton synchrotron (SPS) is the second largest accelerator at CERN where protons are accelerated between 16 and 450 GeV/c. Beam losses, leading to the mixed-field radiation of up to MGy magnitude, pose a threat to the reliability of the electronic equipment and polymer materials located in the tunnel and its vicinity.

A muon collider would enable the big jump ahead in energy reach that is needed for a fruitful exploration of fundamental interactions. The challenges of producing muon collisions at high luminosity and 10 TeV centre of mass energy are being investigated by the recently-formed International Muon Collider Collaboration. [...]
