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. [...]

Recent updates in the impedance characterization of the CERN PS Booster Finemet RF system / Neroni, Michela (CERN ; Rome U.) ; Albright, Simon (CERN) ; Damerau, Heiko (CERN) ; Gnemmi, Giulia (CERN) ; Haase, Matthias (CERN) ; Mostacci, Andrea (Rome U.) ; Paoluzzi, Mauro (CERN) ; Vollinger, Christine (CERN)
During the last long shutdown of the accelerators at CERN (LS2), the main radio frequency system of the Proton Synchrotron Booster (PSB) was upgraded. A widebandsystem with Finemet magnetic alloy cavities driven by solid-state amplifiers replaced several different ferrite-loaded cavities. [...]

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.

Impedance reduction of the beam gas ionization monitors for the CERN SPS / Bursali, Hikmet (CERN) ; Andreazza, William (CERN) ; Khatri, Ghanshyambhai (CERN) ; Ramos Garcia, Maria Teresa (CERN) ; Storey, James (CERN) ; Vollenberg, Wil (CERN) ; Vollinger, Christine (CERN)
The beam gas ionization monitors (BGIs) are non-destructive instruments to measure the transverse beam profiles. With the goal to double the beam intensity in the injector chain for the High-Luminosity Large Hadron Collider (HL-LHC), any element contributing to the overall beam coupling impedance requires an in-depth impedance evaluation from the design stage. [...]

Mitigation of beam coupling impedance for the wire scanners in the CERN Super Proton Synchrotron / Vollinger, Christine (CERN) ; Sullivan, Michael (Rutherford Appleton Laboratory ; CERN) ; Neroni, Michela (CERN ; Rome U.)
The beam wire scanners of the CERN Super Proton Synchrotron (SPS) experienced multiple failures of their carbon wires caused by the high-intensity beam during a very short period in April 2023. Different modifications of the existing instrument were therefore studied to reduce the beam-induced power without compromising its functionality nor negatively affecting the beam coupling impedance.

Simulation and RF Measurement Report to Determine the Longitudinal Beam Coupling Impedance in the SPS-BGI / Bursali, Hikmet (CERN) ; Vollinger, Christine (CERN)
The Beam Gas Ionization (BGI) monitors are non-destructive beam diagnostic devices to measure the transverse beam profiles in the horizontal and vertical planes. [...]

Beam Coupling Impedance of the Main Extraction Kickers in the CERN PS / Neroni, Michela (CERN ; U. Rome La Sapienza (main)) ; Barnes, Michael (CERN) ; Lasheen, Alexandre (CERN) ; Mostacci, Andrea (U. Rome La Sapienza (main)) ; Popovic, Branko (Argonne) ; Vollinger, Christine (CERN)
In view of the High Luminosity (HL) upgrade of the LHC, the beam intensity must be doubled in the injector chain. To perform reliable beam dynamics simulations, the beam coupling impedance in the injectors, such as the Proton Synchrotron (PS), must be followed closely by including all contributing elements into the impedance model. [...]

Beam Performance with the LHC Injectors Upgrade / zannini, C (CERN) ; Wegner, R (CERN) ; Vollinger, C (CERN) ; Veness, R (CERN) ; Velotti, F (CERN) ; Sullivan, M (CERN) ; Steerenberg, R (CERN) ; Spierer, A (CERN) ; Skowronski, P (CERN) ; Sito, L (CERN) et al.
The LHC Injectors Upgrade (LIU) project was put in place between 2010 and 2021 to increase the intensity and brightness in the LHC injectors to match the challenging requirements of the High-Luminosity LHC (HL-LHC) project, while ensuring reliable operation of the injectors complex up to the end of the HL-LHC era (ca. 2040).
