Optics Measurements with the Transverse Damper in the Large Hadron Collider / Nissinen, Tuuli (University of Tampere (FI))
Effective control of beam optics is critical for achieving the luminosity targets in particle colliders such as the Large Hadron Collider (LHC). The search of new discoveries requires even higher beam intensities and smaller beam sizes at collision points, emphasizing the significance of optics corrections. [...]

Ideas for a slow extraction via SPS LSS4 or LSS6 to a future PBC-SBN beamline / Jebramcik, Marc Andre (CERN) ; Arrutia, Pablo (CERN) ; Charitonidis, Nikolaos (CERN)
Within the scope of the Physics Beyond Colliders (PBC) framework and its Conventional Beams Working Group (CBWG), a study for a future Short-Baseline Neutrino Beamline (SBN) at CERN is ongoing. In this context, a preliminary conceptual feasibility analysis of different options of placing the beamline at the PS or the SPS has been carried out. [...]

Design and optimization of higher order mode couplers for the superconducting cavities of the PERLE energy recovery Linac / Barbagallo, Carmelo (U. Paris-Saclay)
The Powerful Energy Recovery Linac for Experiments (PERLE) is an energy recovery linac (ERL) facility based on superconducting radio-frequency (SRF) technology to be hosted at the Laboratoire de Physique des 2 Infinis Irène Joliot-Curie (IJCLab) in France. With a target beam power of 10 MW, PERLE aims to demonstrate the high-current, continuous wave, multi-pass operation to validate options for future high-energy machines, such as the 50 GeV ERL proposed for the Large Hadron electron Collider (LHeC) and the Future Circular electron-hadron Collider (FCC-eh), and host dedicated particle physics and nuclear experiments.

Beam coupling impedance of the main extraction kickers in the CERN PS / Neroni, M (CERN ; U. Rome La Sapienza (main)) ; Barnes, M J (CERN) ; Lasheen, A (CERN) ; Mostacci, A (U. Rome La Sapienza (main)) ; Popovic, B (Argonne) ; Vollinger, C (CERN)
In view of the High Luminosity (HL) upgrade of the LHC, thebeam intensity must be doubled in the injector chain. To performreliable beam dynamics simulations, the beam coupling impedance inthe injectors, such as the Proton Synchrotron (PS), must be followedclosely by including all contributing elements into the impedancemodel.

Mitigation Strategies for the Instabilities Induced by the Fundamental Mode of the HL-LHC Crab Cavities / Giacomel, Lorenzo (CERN) ; Baudrenghien, Philippe (CERN) ; Buffat, Xavier (CERN) ; Calaga, Rama (CERN) ; Mounet, Nicolas (CERN)
The transverse impedance is one of the potentially limiting effects for the performance of the High-Luminosity Large Hadron Collider (HL-LHC). In the current LHC, the impedance is dominated by the resistive-wall contribution of the collimators at typical bunch-spectrum frequencies, and is of broad-band nature. [...]

Tracking studies for the FCC-ee collimation system design / Broggi, G (Rome U. ; Frascati ; CERN)
The Future Circular electron-positron Collider (FCC-ee) is being designed for stored beam energies up to 17.8 MJ, a value almost two orders of magnitude higher than any previous lepton collider. In this new regime, collimators are needed not only to control experimental backgrounds, but also to protect the machine from magnet quenches, or even damage. [...]
