Status on the Development of the Nb$_3$Sn 12 T Falcon Dipole for the FCC-hh- / Valente, R U (LASA, Segrate) ; Ballarino, A (CERN) ; Bersani, A (INFN, Genoa) ; Bracco, M (INFN, Genoa ; Genoa U.) ; Burioli, S (INFN, Genoa) ; Caiffi, B (INFN, Genoa) ; Matteis, E De (LASA, Segrate) ; Farinon, S (INFN, Genoa) ; Gagno, A (INFN, Genoa ; Genoa U.) ; Levi, F (INFN, Genoa ; Genoa U.) et al.
The quest for advancing science and technology continues with the Future Circular Collider (FCC), which requires 16 T bending dipoles to be installed along its 100 km tunnel to achieve a center-of-mass energy of 100 TeV, in its hadron-hadron version. The promising Nb$_3$Sn technology for superconducting magnets presents a potential solution for large-scale production. [...]

Design of a Common Coil Magnet Using Existing Racetrack Model Coils (RMC) / García-Matos, J A (Madrid, CIEMAT ; Madrid, Escuela Tec. Sup. Ing. Ind. ; GIFT, Spain) ; Jardim, C Martins (Madrid, CIEMAT) ; Toral, F (Madrid, CIEMAT) ; Bermudez, S Izquierdo (CERN) ; Perez, J C (CERN)
The common coil configuration was one of the layouts studied as a candidate to build the required high-field magnets for future colliders, specifically FCC-hh at CERN. The design of the structure to support the large electromagnetic forces and the protection system have been identified as the main challenges. [...]

Test Results From CD1 Short CCT Nb-Sn Dipole Demonstrator and Considerations About CCT Technology for the FCC-Hh Main Dipole / Auchmann, B (PSI, Villigen ; CERN) ; Araujo, D M (PSI, Villigen) ; Brem, A (PSI, Villigen) ; Daly, M (PSI, Villigen) ; Felder, R (PSI, Villigen) ; Feuvrier, J (CERN) ; Hug, C (PSI, Villigen) ; Kirby, O (PSI, Villigen) ; Mangiarotti, F (CERN) ; Milanese, A (CERN) et al.
In this article, we attempt to summarize the 5-year long involvement of PSI through the CHART MagDev program with R&D; on the Canted Cosine Theta (CCT) technology as a candidate for an FCC-hh main dipole magnet. We present the test results of the Canted Dipole 1 (CD1) 1-m-long 10-T Nb$_{3}$Sn demonstrator magnet, as well as a subjective list of ‘pros and cons' of CCT for the FCC-hh that we compiled along the way.

Reliability Engineering of Cryocooler-Based HTS Magnets for FCC-ee / Kosse, J (PSI, Villigen) ; Koratzinos, M (PSI, Villigen ; CERN) ; Auchmann, B (PSI, Villigen ; CERN)
The objective of this study is to demonstrate the feasibility of reliable accelerator operation using a main ring based on a large number of superconducting magnets with individual cooling systems. This can be achieved by employing some redundancy within the cooling modules. [...]

Optimized Monochromatization under Beamstrahlung for Direct Higgs Production / Valdivia Garcia, Marco Alan
At the FCC-ee collider, the direct s-channel Higgs production can be accomplished by operating at a beam energy of 62.5 GeV and by introducing a nonzero horizontal dispersion at the collision point for the purpose of monochromatization [...]

Irradiation Induced Aging of Epoxy Resins for Impregnation of Superconducting Magnet Coils / Parragh, D M (CERN) ; Scheuerlein, C (CERN) ; Piccin, R (CERN) ; Ravotti, F (CERN) ; Pezzullo, G (CERN) ; Ternova, D (CERN) ; Taborelli, M (CERN) ; Lehner, M (Vienna, Tech. U., Atominst.) ; Eisterer, M (Vienna, Tech. U., Atominst.)
Understanding the effect of radiation on the functional properties of epoxy resins is crucial for their application in future particle accelerators like the Future Circular Collider (FCC). We compare the irradiation induced aging rates of six epoxy resin systems that can be used for the vacuum impregnation of magnet coils. [...]

Evaluation of the impact of REBCO-coated conductors on the resistive wall impedance of the FCC-hh / Tagdulang, N D (CELLS - ALBA, LLS) ; Günzel, T (CELLS - ALBA, LLS) ; Pont, M (CELLS - ALBA, LLS) ; Krkotic, P (CERN) ; O'Callaghan, J M (Barcelona, Polytechnic U.)
The beam screen for the Future Circular hadron-hadron Collider (FCC-hh) has a baseline design based on a copper (Cu) coating. Calculations have indicated that the resistive wall impedance will be the major contributor to the beam impedance for the FCC-hh at both injection and collision and that Cu might be on the limit to ensure beam stability.

Electron cloud build-up studies for FCC-ee / Sabato, L (Ecole Polytechnique, Lausanne) ; Pieloni, T (Ecole Polytechnique, Lausanne) ; Iadarola, G (CERN) ; Mether, L (CERN)
The Future Circular Collider (FCC) study is developing designs for a new research infrastructure to host the next generation of higher performance particle colliders to extend the research currently being conducted at CERN. In particular, FCC-ee is an electron-positron collider, which is the first stage towards a 100 TeV proton-proton collider FCC-hh.FCC-ee may be affected by electron cloud (e-cloud) and the strongest effects are foreseen for the Z configuration, due to the highest number of bunches, which corresponds to the smallest bunch spacing.
