RF design and optimization of the high-energy linac for the FCC-ee injector complex
/ Kurtulus, A (CERN ; ETH, Zurich (main)) ; Grudiev, A (CERN) ; Latina, A (CERN) ; Bettoni, S (PSI, Villigen) ; Craievich, P (PSI, Villigen) ; Raguin, J -Y (PSI, Villigen)
The high-energy linac of the Future Circular Collider electron-positron (FCC-ee) injector complex requires high-performance rf accelerating structures to efficiently accelerate beams up to 20 GeV while ensuring operational stability. This study presents an analytical approach to the rf design of traveling-wave structures, incorporating a pulse compression system to enhance power efficiency and meet the demanding FCC-ee specifications.

Future challenges for CERN’s ion injector complex
/ Slupecki, Maciej (CERN) ; del Álamo, D (CERN) ; Fernández, R Alemany (CERN) ; Bartosik, H (CERN) ; Bellodi, G (CERN) ; Birtwistle, T (CERN) ; Bodart, D (CERN) ; Bruce, R (CERN) ; Cravero, J M (CERN) ; Damerau, H (CERN) et al.
The ion injector complex at CERN supplies ions for collisions at the Large Hadron Collider (LHC) and for fixed-target physics programmes at the Super Proton Synchrotron (SPS) and Proton Synchrotron (PS). In recent years, there has been growing interest in experiments with lighter ions than lead within the ion-physics community. [...]

The beam dynamics case of beam-beam wire compensators for the HL-LHC era
/ Bélanger, Philippe (TRIUMF ; U. British Columbia (main)) ; Kaltchev, Dobrin (TRIUMF) ; Sterbini, Guido (CERN) ; Baartman, Rick (TRIUMF)
Beam-beam long-range interactions are known to be a strong source of non-linearities in hadron colliders, undermining the performance of the LHC during proton-proton collisions. In order to enhance the luminosity production of the machine and increase the tolerance of the working point after the High Luminosity upgrade of the LHC (HL-LHC), dedicated correctors such as beam-beam wire compensators can be used. [...]

Significance of Corrosion Phenomena for Magnets of Accelerators, Fusion and High Energy Physics Experiments
/ Sgobba, Stefano (CERN) ; Aviles Santillana, Ignacio (CERN) ; Fontenla, Ana Teresa Perez (CERN) ; Koizumi, Norikiyo (Natl. Inst. Quantum Radiological Sci. Tech., Chiba) ; Pearce, Robert (Euratom, St. Paul Lez Durance) ; Villers, Frantz (Euratom, St. Paul Lez Durance) ; Vitupier, Guillaume (Euratom, St. Paul Lez Durance)
Although superconducting accelerator and fusion magnets operate at cryogenic temperature and in most cryogenic applications corrosion is not an issue, it is essential to avoid corrosion phenomena that may occur during production and fabrication of parts and components of magnet systems, or during their installation, assembly or maintenance. A delayed leak or a structural failure that would arise in operation due to onset of corrosion phenomena at an earlier stage could lead to grave consequences due to many such components becoming embedded and virtually unrepairable.

Beam-based impedance measurement of HL-LHC low-impedance collimators
/ Kurtulus, A (Zurich, ETH ; CERN) ; Amorim, D (CERN) ; Biancacci, N (CERN) ; Buffat, X (CERN) ; Giacomel, L (CERN) ; Leuthold, J (Zurich, ETH) ; Mounet, N (CERN) ; Redaelli, S (CERN) ; Smajic, J (Zurich, ETH)
The objective of the High Luminosity Large Hadron Collider (HL-LHC) upgrade is to attain an instantaneous luminosity that is 5 times greater than the design value of the LHC. This requires nearly 2 times higher beam intensity compared to the operational LHC value during Run 2 (2015–2018). [...]
