Future Circular Lepton Collider Vibrational Crosstalk / Lersnimitthum, Purinut (Chulalongkorn U.) ; Piccini, Audrey (CERN) ; Carra, Federico (CERN) ; Boonyatee, Tirawat (Chulalongkorn U.) ; Wansophark, Niphon (Chulalongkorn U.) ; Ajavakom, Nopdanai (Chulalongkorn U.)
CERN, the European Organisation for Nuclear Research is studying the feasibility of the Future Circular Collider, considering both financial and technical aspects. One of the challenges is that the performance of particle accelerators relies on the dynamic stability of structures, affected by multiple sources of vibrations, including crosstalk vibration between two particle accelerators, the Booster and Collider, in the Future Circular Lepton Collider.

Monochromatization interaction region optics design for direct s-channel Higgs production at FCC-ee / Zhang, Z. (Beijing, Inst. High Energy Phys. ; IJCLab, Orsay) ; Faus-Golfe, A. (IJCLab, Orsay) ; Korsun, A. (IJCLab, Orsay) ; Bai, B. (Harbin Inst. Tech.) ; Jiang, H. (Lancaster U. (main)) ; Oide, K. (Geneva U. ; KEK, Tsukuba) ; Raimondi, P. (Fermilab) ; d'Enterria, D. (CERN) ; Zhang, S. (Beijing, Inst. High Energy Phys.) ; Zhou, Z. (Beijing, Inst. High Energy Phys.) et al.
The FCC-ee offers the potential to measure the electron Yukawa coupling via direct s-channel Higgs production, e+ e- -> H, at a centre-of-mass (CM) energy of 125 GeV. This measurement is significantly facilitated if the CM energy spread of e+ e- collisions can be reduced to a level comparable to the natural width of the Higgs boson, Γ_H = 4.1 MeV, without substantial loss in luminosity [...]

Forming limit diagram of annealed copper OFE thick sheets for optimized hydroforming of superconducting RF cavities / Gallifa-Terricabras, Adrià (CERN) ; Swieszek, Joanna Sylwia (CERN) ; Smakulska, Dorota (CERN) ; Ruiz-Palenzuela, Berta (CERN) ; Garlaschè, Marco (CERN)
Coated superconducting radio-frequency (SRF) cavities are planned to be implemented in the Future Circular Collider (FCC) at the European Organization for Nuclear Research (CERN). The interest in industrialized and high-performance processes for fabrication of the corresponding copper substrates has thus risen. [...]

Non-invasive Beam Diagnostic Development for FCC using Cherenkov Diffraction Radiation in Dielectric Materials / Schloegelhofer, Andreas
Cherenkov diffraction radiation (ChDR) refers to the emission of electromagnetic radiation when a charged particle travels in the vicinity of dielectric matter, and the particle’s velocity exceeds the phase velocity of electromagnetic radiation in the dielectric [...]

Subscale Stress-Managed Common Coil Design / Araujo, D M (PSI, Villigen) ; Auchmann, B (PSI, Villigen ; CERN) ; Brem, A (PSI, Villigen) ; Daly, M (PSI, Villigen) ; Michlmayr, T (PSI, Villigen) ; Müller, C (PSI, Villigen) ; Garcia-Rodrigues, H (PSI, Villigen) ; Sotnikov, D (PSI, Villigen) ; Milanese, A (CERN)
In the context of the High-Field Magnet (HFM) Programme, hosted at CERN, and the Swiss Accelerator Research and Technology (CHART) Initiative, hosted at PSI, the Magnet Development (MagDev) project aims to contribute to the Future Circular Collider (FCC) studies through, among others: (i) research on enabling technologies and (ii) high-field Low Temperature superconducting (LTS) and High Temperature Superconducting (HTS) magnets. After a first experience with the CD1 magnet, a Canted-Cosine-Theta (CCT) Nb3Sn demonstrator, a roadmap has been established with milestones ranging from enabling technologies tested in powered samples and coils, to ultimate-field and hybrid LTS/HTS short magnets.

Effect of Irradiation Temperature and Atmosphere on Aging of Epoxy Resins for Superconducting Magnets / Parragh, David Mate (CERN) ; Scheuerlein, Christian (CERN) ; Martin, Noémie (Lyon U.) ; Piccin, Roland (CERN) ; Ravotti, Federico (CERN) ; Pezzullo, Giuseppe (CERN) ; Koettig, Torsten (CERN) ; Lellinger, Dirk (Unlisted, DE)
The superconducting magnets of future particle accelerators will be exposed to high irradiation doses at cryogenic temperatures. To investigate the effect of irradiation temperature and atmosphere on the aging behavior, we have characterized the changes in thermomechanical properties of six epoxy resins for potential use in superconducting magnets after irradiation up to 20 MGy in ambient air, inert gas, and liquid helium.
