/ Caiffi, Barbara (INFN, Genoa) ; Alfonso, Luca (INFN, Genoa) ; Bersani, Andrea (INFN, Genoa) ; Bottura, Luca (CERN) ; Farinon, Stefania (INFN, Genoa) ; Gagno, Andrea (INFN, Genoa) ; Levi, Filippo (INFN, Genoa) ; Mariani, Francesco (Milan Bicocca U. ; LASA, Segrate) ; Mariotto, Samuele (Milan Bicocca U. ; LASA, Segrate) ; Musenich, Riccardo (INFN, Genoa) et al.
The International Muon Collider Collaboration (IMCC) has been formed with the aim of delivering a feasibility study on a Muon Collider facility, as recommended by the European Strategy for Particle Physics and supported by the European Union through the Grant Agreement 101094300. Such facility would allow to study frontier physics with a 10 km collider ring and a muon center of mass energy of 10 TeV. [...]

Abstract
The reliance on fossil-derived components in the design of metamaterials and metastructures presents sustainability and environmental challenges, prompting the development of alternative solutions. In response, this study proposes a fully bio-based and modular metastructure composed of rods extracted from the giant bamboo (Dendrocalamus asper) and plant-based polymeric joints derived from soybean (Glycine max) and castor oil (Ricinus communis), aiming to offer a sustainable alternative for load-bearing structural components [...]

With a circumference of approximately 91 km, the Future Circular electron-positron Collider, FCC-ee, aims for unprecedented luminosities at beam energies from 45.6 to 182.5 GeV. A major challenge is reaching its design performance in the presence of magnet misalignments and field errors. [...]

Parameter space for the magnetic design of Nested Magnets in the FCC-ee arc cell
/ Garcia Jaimes, Cristobal Miguel (Ecole Polytechnique, Lausanne, LPAP) ; Thabuis, Adrien (CERN) ; Auchmann, Bernhard (PSI, SLS) ; Kosse, Jaap (PSI, SLS) ; van Riesen-Haupt, Léon (Ecole Polytechnique, Lausanne, LPAP) ; Koratzinos, Michael (CERN) ; Seidel, Mike (Ecole Polytechnique, Lausanne, LPAP) ; Tomas, Rogelio (CERN) ; Pieloni, Tatiana (Ecole Polytechnique, Lausanne, LPAP)
The Future Circular Collider (FCC-ee) is designed to explore the Z and W± bosons, along with the Higgs boson and top quark, achieving exceptionally high luminosity. In order to minimize the energy lost per turn due to Synchrotron Radiation (SR) we explore the use of Nested Magnets (NMs) into the arcs cell. [...]

Initial design of a proton complex for the Muon Collider
/ Johannesson, Sofia (ESS, Lund) ; Lombardi, Alessandra (CERN) ; Gorzawski, Arkadiusz (ESS, Lund) ; Kelliher, David (Rutherford Appleton Laboratory) ; Laface, Emanuele (ESS, Lund) ; Vojskovic, Isabella (ESS, Lund) ; Milas, Natalia (ESS, Lund) ; Machida, Shinji (Rutherford Appleton Laboratory) ; Gilardoni, Simone (CERN)
The proton complex is the first piece in the Muon Collider, it comprises a high power acceleration section, a compressor and a target delivery system. For the International Muon Collider Collaboration we are investigating the possibility of having a full energy 5-GeV linac followed by an accumulator and a compressor ring and finally a target delivery system.

Review of MAD-X for FCC-ee studies

The design of the electron-positron Future Circular Collider (FCC-ee) challenges the requirements on optics codes (like MAD-X) in terms of accuracy, consistency, and performance. Traditionally, MAD-X uses a transport formalism by expanding the transfer map about the origin up to second order to compute optics functions and synchrotron radiation integrals in the TWISS and EMIT modules.

The Future Circular Electron-Positron Collider (FCC-ee) represents a cutting-edge particle physics facility designed to further investigate the Z, W± and Higgs boson in addition to the top quark. The implementation of Nested Magnets (NMs) in the FCC-ee arc cells would maintain high luminosity and reduce its energy consumption. [...]

Update of the PLACET2 code for the low-energy acceleration stages of the muon collider
/ Desire Valdor, Paula (CERN ; U. Groningen (main)) ; Latina, Andrea (CERN) ; Stechauner, Bernd (CERN ; TU Vienna) ; Costa, Raul (Uppsala U. (main))
This work describes improvements made to the tracking code PLACET2 to make it possible to simulate the acceleration from 250 MeV to 63 GeV in a future muon collider. This software was selected because of its unique ability to optimally simulate recirculating linacs, which are part of the proposed layout for this initial muon acceleration stage. [...]
