Operational experience and reliability of the new CERN Linac4 / Sargsyan, Edgar (CERN) ; Lombardi, Alessandra (CERN) ; Bellodi, Giulia (CERN) ; Lallement, Jean-Baptiste (CERN) ; Skowronski, Piotr (CERN) ; Wegner, Rolf (CERN)
Since its completion in 2017, Linac4, the new 160 MeV proton injector for the CERN accelerator complex, has undergone some tests to assess and improve reliability, until being connected to the Proton Synchrotron Booster (PSB) during the 2018-2020 Long Shutdown 2 (LS2). The performance requirements for the LHC high-luminosity upgrade have been successfully met, and during its first three complete years of operation the linac has shown high reliability figures. [...]

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.

Chapter 21: Beam from Injectors: The LHC Injectors Upgrade (LIU) Project / Meddahi, M (CERN) ; Rumolo, G (CERN) ; Alemany, R (CERN) ; Bartosik, H (CERN) ; Bellodi, G (CERN) ; Coupard, J (CERN) ; Damerau, H (CERN) ; Di Giovanni, G P (CERN) ; Funken, A (CERN) ; Garoby, R et al.
The LHC Injectors Upgrade (LIU) project aims at increasing the intensity and brightness in the LHC injectors in order to match the challenging requirements of the High-Luminosity LHC (HL-LHC) project, while ensuring high availability and reliable operation of the injectors complex up to the end of the HL-LHC era. Fulfilling this goal requires extensive hardware modifications and new beam dynamics solutions across the entire LHC proton and ion injection chains: the new Linac4, the Proton Synchrotron Booster (PSB), the Proton Synchrotron (PS), the Super Proton Synchrotron (SPS), together with Linac3 and the Low Energy Ion Ring (LEIR) as ion PS injectors.

Benchmarking of PATH and RF-Track in the Simulation of Linac4 / Bellodi, Giulia ; Lallement, Jean-Baptiste ; Latina, Andrea ; Lombardi, Alessandra
A benchmarking campaign has been initiated to compare PATH and RF-Track in modelling high-intensity, low-energy hadron beams. The development of extra functionalities in RF-Track was required to handle an unbunched beam from the source and to ease the user interface. [...]

Linac4 Source and Low Energy Experience and Challenges / Sargsyan, Edgar (CERN) ; Bellodi, Giulia (CERN) ; Di Lorenzo, Francesco (CERN) ; Etxebarria Erdoiza, Jone (CERN) ; Lallement, Jean-Baptiste (CERN) ; Lombardi, Alessandra (CERN) ; O'Neil, Michael (CERN)
At the end of Long Shutdown 2 (LS2), in 2020 Linac4 became the new injector of CERN’s proton accelerator complex. The previous version of the Linac4 H⁻ ion source (IS03), produced an operational pulsed peak beam current of 35 mA, resulting in 27 mA after the Radio-Frequency Quadrupole (RFQ). [...]
