FCC circumference studies based on RF synchronization / Zhang, L H (Hefei, CUST) ; Damerau, H (CERN) ; Karpov, I (CERN) ; Vanel, A L (CERN)
As the study of the Future Circular Collider (FCC) projectprogresses, the choice of the exact circumference of the acceleratortunnel becomes essential. It is defined by RF-related constraints,mainly the RF frequency of the FCC-hh, as well as the revolutionfrequency ratios with the hadron injector. [...]

Training-free performance of the wax-impregnated SuShi septum magnet / Barna, D (Wigner RCP, Budapest) ; Brunner, K (Wigner RCP, Budapest) ; Novák, M (Wigner RCP, Budapest) ; Borburgh, J (CERN) ; Atanasov, M (CERN) ; Lackner, F (CERN) ; Olvegård, M (Uppsala U.) ; Pepitone, K (Uppsala U.) ; Santiago Kern, R (Uppsala U.) ; Svanberg, C (Uppsala U.) et al.
In the framework of the Future Circular Collider Study a new septum magnet concept, nicknamed ‘SuShi’ has been developed, and a prototype was built at Wigner Research Center for Physics, and tested at the FREIA facility of Uppsala University in April 2023. The concept uses a canted cosine theta (CCT)-like superconducting magnet and a passive superconducting shield to create a zero-field and high-field region within its aperture. [...]

First considerations on the supporting structures of FCC-ee booster and collider in the arc regions / Carra, F (CERN) ; Baudin, L (CERN) ; Bauche, J (CERN) ; Artoos, K (CERN) ; Atieh, S (CERN) ; Bertarelli, A (CERN) ; Brunner, O (CERN) ; Capatina, O (CERN) ; Chance, A (Saclay) ; Chemli, S (CERN) et al.
In 2022, the FCC Feasibility Study management mandated aworking group to analyse the best configuration of the FCC-ee tunnelin the arc regions, in view of the construction of a mock-up of thearc half-cell. One of the main and most challenging goals of thestudy, named FCC-ee Arc Half-Cell Mock-up Project, was toperform a preliminary investigation on the principles of supportingthe Short-Straight Sections and dipoles of the half-cells, both forthe booster and for the collider machines.

Development of a Readout Board for an Optical Beam Loss Monitor based on Cherenkov Radiation at CERN / Lima, Erika (Sapienza Universita e INFN, Roma I (IT))
This thesis presents the theory, design, fabrication, and characterization of a sensor electronics board for a novel beam loss monitor based on optical fibres developed at Centre Européenne pour la Recherche Nucléaire (CERN) by the Beam Instrumentation group. An Optical Beam Loss Monitor (OBLM) is a device based on the detection of Cherenkov radiation in optical fibres. [...]

208Pb29+ beam physics studies at the CERN Linac3 in the 2021 run / Montoya Soto, Gaspar Ricardo (Universidad de Guanajuato (MX))
This thesis represents the culmination of a comprehensive exploration into the intricate world of Linac3, a journey undertaken during the 2021 Pb run. Our mission was clear: to close the gap between beam measurements and simulations, with the overarching goal of unraveling the mysteries of beam dynamics and validating the simulation models that underpin Linac3's operation.
