/ Martinek, Petr (CERN) ; Favia, Giorgia (CERN) ; Barnes, Michael (CERN) ; Diaz Zumel, Miguel (CERN) ; Yue, Sen (CERN) ; Kramer, Thomas (CERN) ; Dutheil, Yann (CERN)
A central part of CERN’s Future Circular collider study (FCC) is a ~91 km circumference lepton collider and its injector complex. This contribution outlines the various kicker systems needed to transport the lepton beams from the electron source up to the collider dump system. [...]

A review of the 2023 antiproton physics run in the CERN antimatter factory
/ Bojtar, Lajos (CERN) ; Lefort, Bertrand (CERN) ; Dupuy, Bruno (CERN) ; Gamba, Davide (CERN) ; Joergensen, Lars (CERN) ; Ponce, Laurette (CERN) ; Freyermuth, Pierre (CERN) ; Pasinelli, Sergio (CERN) ; Dutheil, Yann (CERN)
Despite a shorter-than-scheduled physics run due to a hardware problem, the AD/ELENA antiproton complex delivered record beam intensities to the experiments during the 2023 run. This paper reviews the performance of both the CERN Antiproton Decelerator (AD) and the Extra Low ENergy Antiproton (ELENA) decelerator and their associated transfer lines. [...]

Hybrid on-axis and off-axis top-up injection at the future circular lepton collider
/ Yue, Sen (CERN) ; Dutheil, Yann (CERN) ; Bartmann, Wolfgang (CERN) ; Johnson, Eliott (CERN) ; Martinek, Petr (CERN)
In order to maximize the integrated luminosity of the future circular lepton collider (FCC-ee), a top-up injection scheme is required. Amongst the four operation modes of FCC-ee, the Z operation mode has the highest stored beam energy in the collider ring with about 20 MJ per beam. [...]

Radiation to electronics studies for CERN gamma factory-proof of principle experiment in SPS
/ Mazzola, Giuseppe (CERN) ; Di Francesca, Diego (CERN) ; Bilko, Kacper (CERN) ; Esposito, Luigi Salvatore (CERN) ; Garcia Alia, Ruben (CERN) ; Niang, Samuel (CERN) ; Dutheil, Yann (CERN)
The Physics Beyond Colliders is a CERN exploratory study aimed to fully exploit the scientific potential of its accelerator complex. In this initiative, the Gamma Factory experiment aims to produce in the Large Hadron Collider (GF@LHC) high-intensity photon beams in the energy domain up to 400 MeV. [...]

Study of the performance and beam loss limitations during injection of high-intensity LHC proton beams

The LHC Injectors Upgrade project at CERN optimized the injection accelerator chain to deliver proton intensities per bunch of 2.3e+11 ppb. Throughout 2023, the LHC was filled with up to 2464 bunches per beam using a hybrid injection scheme, involving up to 236 bunches per injection, with a maximum intensity per bunch of 1.6e+11 ppb.

Damping ring and transfer lines of FCC-𝑒+𝑒− injector complex
/ Spampinati, Simone (Frascati) ; De Santis, Antonio (Frascati) ; Dutheil, Yann (CERN) ; Etisken, Ozgur (Kirikkale U. ; Frascati) ; Ramjiawan, Rebecca (CERN) ; Milardi, Catia (Frascati)
The Future Circular Collider project is built around two main pillars: the construction of 100 km lepton collider running at increasing energies from the Z-pole to the t-tbar threshold (FCC-ee) followed by a hadron collider in the same tunnel (FCC-hh) to explore unprecedented energy frontier.The realization of FCC-ee relies on a very challenging injector complex that should provide the highest ever realized source of positrons, which will serve the first phase of the collider operations (Z-pole). In this contribution the relevant aspects related to the damping of the high-emittance beam coming from the positron source and the transport of the damped beam within the different LINAC of the injector complex are presented and discussed..

FCC-ee $e^+e^-$ Injection and Booster rRng

The Future Circular electron-positron Collider (FCC-ee) is a proposal for a 91.17 km collider, which would operate in four modes with energies ranging from 45.6 GeV (Z-pole) to 182.5 GeV (ttbar-production). At high energies the beam lifetime could be as low as 6 minutes, requiring the beam to be continuously topped up to reach a high integrated luminosity. [...]
