Electron cloud mitigation techniques for the FCC-ee / Sabato, Luca (Ecole Polytechnique, Lausanne) ; Bartosik, Hannes (CERN) ; Carli, Christian (CERN) ; Iadarola, Giovanni (CERN) ; Mether, Lotta (CERN) ; Pieloni, Tatiana (Ecole Polytechnique, Lausanne) ; Zimmermann, Frank (CERN)
The Future Circular Collider (FCC)-ee is a planned electron-positron collider under development. The future collider would be built in an about 91 km ring-shaped underground tunnel located beneath the French departments of Haute-Savoie and Ain, and the Swiss canton of Geneva. [...]

Resonance gaps, discrepancies, and lines / Tomás García, Rogelio (CERN)
The sequence formed by the fractional tune resonances up to order n exactly coincides with the Farey sequence, Fn. In circular accelerators, it is important to place the tunes in regions free of resonances. [...]

Interplay between sextupole settings and single particle instabilities during the FCC-ee commissioning / Skoufaris, Kyriacos (CERN) ; Garcia Jaimes, Cristobal Miguel (Ecole Polytechnique, Lausanne) ; Tomas, Rogelio (CERN)
The Future Circular Collider of electrons and positrons (FCC-ee) is designed to achieve high luminosity at center-of-mass energies ranging from the Z boson peak to the top quark threshold. During the commissioning phase, specialized optics are essential to accommodate the dynamic needs of machine tuning and beam stabilization. [...]

Double pulse generator for AWAKE scalable discharge plasma source / Torrado, NE (IST, Lisbon (main) ; CERN) ; Amoedo, C (CERN) ; Sublet, A (CERN) ; Taborelli, M (CERN) ; Pinto, SF (Lisbon, INESC-ID) ; Silva, JF (Lisbon, INESC-ID) ; Lopes, NC (IST, Lisbon (main))
High-voltage pulsed discharges can produce suitable plasmas for wakefield acceleration experiments, such as the Advanced Wakefield Experiment (AWAKE) at CERN. Using two successive voltage pulses, the first for plasma ignition (~20 kV) followed by a second pulse (~500 A) for plasma heating, it is possible to effectively obtain a highly reproducible plasma lasting tens of microseconds, by taking advantage of the low impedance state created by the first pulse.A discharge plasma source (DPS), based on this principle was installed in the AWAKE experiment producing over 21 thousand plasma discharges and was tested with a double-plasma set-up (3.5 + 6.5 m plasma length) using two pulse generators and a shared cathode. [...]

Status of the CERN optics measurement and correction analysis tools / Dilly, Joschua (CERN) ; Wegscheider, Andreas (CERN) ; Maclean, Ewen (CERN) ; Carlier, Felix (CERN) ; Soubelet, Felix (CERN) ; Gray, Joshua (CERN) ; Le Garrec, Mael (CERN) ; Tomas, Rogelio (CERN) ; Horney, Sasha (CERN) ; Persson, Tobias (CERN)
With a change in the LHC machine optics foreseen for 2025 and the possible reduction of beta-star, optics commissioning will become even more of a challenge for the CERN Optics Measurement and Correction (OMC) team. In particular, the increased sensitivity of the optics to non-linear imperfections, requiring a plethora of accurate measurements, is expected to be a time consuming task. [...]

Noise Analysis and Variance Reduction of Continuous Impedance Measurements of Energized Superconducting Magnets / Christensen, Magnus Bøgh Borregaard (CERN ; Aalborg U.) ; Koch, Peter (Aalborg U.) ; Podzorny, Tomasz (CERN) ; Østergaard, Jan (Aalborg U.)
Superconducting magnet impedance measurements are vital for assessing magnet health and electrical integrity. To fur- ther enhance monitoring capabilities beyond contemporary meth- ods that largely rely on manual intervention, recent efforts have focused on enabling in situ and continuous measurements during magnet operation.

Application of distributed temperature sensor for fire and cryogenic leak detection in accelerator tunnels / Dole, Michael (CERN) ; Di Francesca, Diego (CERN) ; Nissen, Henrik (CERN) ; Blanc, Jeremy (CERN) ; Bremer, Johan (CERN) ; FERNANDEZ, Julien (CERN) ; Dufay-Chanat, Laetitia (CERN) ; Contini, Lorenzo (CERN) ; Van de veire, Matthias (CERN) ; Rios, Oriol (CERN) et al.
High-energy accelerators like CERN’s Large Hadron Collider (LHC) present hazards characterized by temperature variations such as cryogenic leak or fire. Considering that LHC tunnels are large, underground, and radioactive areas, alternatives to traditional systems are explored to improve hazard detection. [...]
