Effects of Cavity Pre-Detuning on RF Power Transients at Injection into the LHC / Karlsen-Bæck, Birk Emil (CERN ; Rome U.) ; Argyropoulos, Theodoros (CERN) ; Butterworth, Andrew (CERN) ; Calaga, Rama (CERN) ; Karpov, Ivan (CERN) ; Timko, Helga (CERN) ; Zampetakis, Michail (CERN)
At injection into the LHC, the RF system is perturbed by beam-induced voltage resulting in strong RF power transients and the instant detuning of the cavities. The automatic tuning system, however, needs time for the mechanical compensation of the resonance frequency to take place. [...]

Upgrade of the CERN SPS Extraction Protection Elements TPS / Borburgh, Jan (CERN) ; Balhan, Bruno (CERN) ; Barnes, Michael (CERN) ; Baud, Cedric (CERN) ; Fraser, Matthew (CERN) ; Kain, Verena (CERN) ; Maciariello, Fausto (CERN) ; Steele, Genevieve (CERN) ; Velotti, Francesco (CERN)
In 2006 the protection devices upstream of the septa in both extraction channels of the CERN SPS to the LHC were installed. Since then, new beam parameters have been proposed for the SPS beam towards the LHC in the framework of the LIU project. [...]

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
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 [...]

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. [...]
