Simulation and measurement of the interplay between electron cooling, impedance, intrabeam scattering, and space charge for coasting beams / Biancacci, N (CERN) ; Zampetakis, M (CERN ; Crete U.)
The Low Energy Ion Ring (LEIR) at CERN is the first synchrotron in the Large Hadron Collider ions injector chain. The performance of LEIR is mainly determined by the number of charges extracted from the machine and transferred to the downstream chain of accelerators. [...]

Machine Induced Backgrounds in the FCC-ee MDI Region and Beamstrahlung Radiation / Ciarma, Andrea (CERN) ; Boscolo, Manuela (Frascati) ; Ganis, Gerardo (CERN) ; Perez, Emmanuelle (CERN)
The new design for the central chamber of the FCC-ee beam pipe has a reduced radius of R=10mm and length of L=18cm, allowing to have the inner layer of the Vertex Detector Barrel closer to the interaction point. The effect of the background induced occupancy due to Incoherent Pairs Creation (IPC), beam losses in the MDI area and Synchrotron Radiation are explored for the CLD detector, using the updated version of the Vertex Detector for the new central beam pipe.

Measurement for the $e^+$ beam purity at the CERN-SPS H8 beamline / Bisio, Pietro (INFN e Universita Genova (IT)) ; Celentano, Andrea (INFN e Universita Genova (IT)) ; Marsicano, Luca (INFN e Universita Genova (IT)) ; Bondi, Mariangela (INFN e Laboratori Nazionali di Frascati (IT)) ; Marini, Anna (INFN e Universita Genova (IT))
This Note describes the $e^+$-beam purity measurement for the H8 beamline of the Super Proton Synchrotron (SPS) at CERN. This study was performed in the context of the POKERINO prototype characterization, conducted during a week of measurements in the summer of 2023 at the H8 beamline. [...]

Reliability studies for CERN’s new safe machine parameter system / Blaszkiewicz, Milosz (CERN) ; Apollonio, Andrea (CERN) ; Bolton, Samuel (CERN) ; Colinet, Antoine (CERN) ; Romera, Iván (CERN) ; Secondo, Raffaello (CERN) ; Uythoven, Jan (CERN) ; Wollmann, Daniel (CERN) ; Felsberger, Lukas (CERN)
The Safe Machine Parameter system (SMP) is a critical part of the machine protection system in CERN’s Large Hadron Collider (LHC) and the Super Proton Synchrotron (SPS). It broadcasts safety-critical parameters like beam energy, beam intensity, the beta functions and flags indicating safety levels of the beam to other machine protection elements. [...]

Investigations of losses on the CERN SPS flat bottom with HL-LHC type beams / Lasheen, Alexandre (CERN) ; Bartosik, Hannes (CERN) ; Damerau, Heiko (CERN) ; Demetriadou, Despina (CERN) ; Vinten, Evin (CERN) ; Hermes, Pascal (CERN) ; Kain, Verena (CERN) ; Karpov, Ivan (CERN) ; Papotti, Giulia (CERN) ; Vadai, Mihaly (CERN) et al.
The High-Luminosity LHC (HL-LHC) project at CERN aims at doubling the beam intensity and the brightness. To achieve this unprecedented performance, the LHC injectors were upgraded during the Long Shutdown 2 (2019-2021) to overcome limitations such as space charge and beam instabilities. [...]
