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. [...]

Empty-bucket techniques for spill-quality improvement at the CERN Super Proton Synchrotron / Arrutia Sota, Pablo A (CERN) ; Fraser, Matthew A (CERN) ; Hagmann, Gregoire (CERN) ; Kain, Verena (CERN) ; Papotti, Giulia (CERN) ; Spierer, Arthur (CERN) ; Velotti, Francesco M (CERN) ; Burrows, Philip N (JAI, UK) ; Piandani, Roberto (San Luis Potosi U.)
Synchrotrons can provide long spills of particles by employing resonant extraction where the circulating beam is slowly ejected over thousands to millions of turns by exploiting the amplitude growth caused by a transverse resonance. In the CERN Super Proton Synchrotron (SPS), this method is used to satisfy the experimental requests of the North Area. [...]

Performance of the Ion Chain at the CERN Injector Complex and Transmission Studies During the 2023 Slip Stacking Commissioning / Slupecki, Maciej (CERN) ; Albright, Simon (CERN) ; Alemany-Fernández, Reyes (CERN) ; Angoletta, Maria Elena (CERN) ; Argyropoulos, Theodoros (CERN) ; Bartosik, Hannes (CERN) ; Baudrenghien, Philippe (CERN) ; Bellodi, Giulia (CERN) ; Bozzolan, Michele (CERN) ; Bruce, Roderik (CERN) et al.
The 2023 run has been decisive for the LHC Ion Injector Complex. It demonstrated the capability of producing full trains of momentum slip stacked lead ions in the SPS. [...]

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. [...]

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).

Operational Tool for Automatic Setup of Controlled Longitudinal Emittance Blow-Up in the CERN SPS / Bruchon, Niky (CERN) ; Karpov, Ivan (CERN) ; Madysa, Nico (CERN ; Darmstadt, GSI) ; Papotti, Giulia (CERN) ; Quartullo, Danilo (CERN)
The controlled longitudinal emittance blow-up is necessary to ensure the stability of high-intensity LHC-type beams in the CERN SPS. It consists of diffusing the particles in the bunch core by injecting a bandwidth-limited noise into the beam phase loop of the main 200 MHz RF system. [...]

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. [...]

An improved procedure for energy matching between PS and SPS at CERN / Papotti, Giulia (CERN) ; Cettour Cave, Stephane (CERN) ; Follin, Fabio (CERN) ; Spierer, Arthur (CERN)
Energy matching between two hadron synchrotrons is the adjustment of the magnetic bending fields and beam momentum to obtain a correct transfer between the two. Conventionally, energy matching is achieved by turning off the RF system and measuring the revolution frequency of the de-bunching beam in the receiving accelerator. [...]

SPS fixed target spill quality improvements in the longitudinal plane / Papotti, Giulia (CERN) ; Spierer, Arthur (CERN) ; Quartullo, Danilo (CERN) ; Hagmann, Gregoire (CERN) ; Karpov, Ivan (CERN) ; Piandani, Roberto (San Luis Potosi U.)
The SPS proton fixed target beams are spilled via a third integer resonant extraction, for which high momentum spread is beneficial. To increase the momentum spread prior to the slow extraction, the bunches are stretched at the unstable phase by inverting the sign of the RF voltage. [...]
