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. [...]

Overview of beam intensity issues and mitigations in the CERN-SPS fast wire scanners / Veness, Raymond (CERN) ; Guerrero, Ana (CERN) ; Perez Fontenla, Ana Teresa (CERN) ; Harrison, Anthony (CERN) ; Salvant, Benoit (CERN) ; Zannini, Carlo (CERN) ; Antuono, Chiara (CERN) ; Vollinger, Christine (CERN) ; de la Fuente, Elena (CERN) ; Carra, Federico (CERN) et al.
A new design of fast wire scanner was installed in the CERN injector complex as part of the upgrades linked to the High-Luminosity LHC Project. Initial operations with these beams were good, but during the planned intensity ramp-up one early 2023, all four SPS scanners failed at the same time. [...]

Impedance and thermal studies of the CERN SPS wire scanners and mitigation of wire heating / de la Fuente, Elena (CERN) ; Papazoglou, I (CERN) ; Sito, Leonardo (CERN) ; Andreazza, William (CERN) ; Antuono, Chiara (CERN) ; Bruchon, N (CERN) ; Calaga, Rama (CERN) ; Carra, Federico (CERN) ; Emery, J (CERN) ; Harrison, Anthony (CERN) et al.
All wires of the four CERN SPS rotational wirescanners broke when increasing the beam intensity towards the target for the LHC Injector Upgrade in 2023. Impedance and thermal studies were immediately launched, with simulations and measurements indicating that beam induced heating from resonant modes on the thin wire could be sufficient to cause these breakages.

Intensity Effects in a Chain of Muon RCSs / Métral, E (CERN) ; Chancé, A (U. Paris-Saclay) ; Batsch, Fabian (CERN) ; Amorim, David (CERN) ; Chancé, Antoine (Saclay) ; Damerau, Heiko (CERN) ; Grudiev, Alexej (CERN) ; Karpov, Ivan (CERN) ; Métral, Elias (CERN) ; Schulte, Daniel (CERN) et al.
The muon collider offers an attractive path to a compact, multi-TeV lepton collider. However, the short muon lifetime leads to stringent requirements on the fast energy increase. [...]

Advances on LHC RF Power Limitation Studies at Injection / Timko, Helga (CERN) ; Argyropoulos, Theodoros (CERN) ; Calaga, Rama (CERN) ; Catalán Lasheras, Nuria (CERN) ; Iliakis, Konstantinos (CERN) ; Karlsen-Bæck, Birk Emil (CERN ; Rome U.) ; Karpov, Ivan (CERN) ; Zampetakis, Michail (CERN)
The average power consumption of the main RF system during beam injection in the High-Luminosity Large Hadron Collider is expected to be close to the maximum available klystron power. Power transients due to the mismatch of the beam and the action of control loops will exceed the available power. [...]

Longitudinal Collective Effects at Beam Transfer from PS to SPS at CERN / Lasheen, Alexandre (CERN) ; Damerau, Heiko (CERN) ; Karpov, Ivan (CERN) ; Papotti, Giulia (CERN) ; Vinten, Evin (CERN)
The hardware upgrades of the LHC Injectors Upgrade (LIU) project at CERN were completed during the Long Shutdown 2 (2019-2021) to prepare the injectors for the beams required by the High Luminosity (HL) LHC. Doubling the bunch intensity leads to new challenges due to collective effects. [...]

Longitudinal Loss of Landau Damping in Double Harmonic RF Systems below Transition Energy / Intelisano, Leandro (CERN ; U. Rome La Sapienza (main)) ; Damerau, Heiko (CERN) ; Karpov, Ivan (CERN)
Landau damping plays a crucial role in ensuring single-bunch stability in hadron synchrotrons. In the longitudinal plane, loss of Landau damping (LLD) occurs when a coherent mode of oscillation moves out of the incoherent synchrotron frequency band. [...]

New Understanding of Longitudinal Beam Instabilities and Comparison with Measurements / Karpov, Ivan (CERN)
Beam instabilities driven by broad- and narrowband impedance sources have been treated separately so far. In this contribution, we present the generalised beam stability analysis based on the concept of van Kampen modes. [...]
