Radiation load studies for the proton target area of a multi-TeV muon collider / Manczak, Jerzy (CERN) ; Frasca, Alessandro (CERN) ; Portone, Alfredo (Fusion for Energy, Barcelona) ; Lechner, Anton (CERN) ; Rogers, Chris (Daresbury) ; Ahdida, Claudia (CERN) ; Schulte, Daniel (CERN) ; Calzolari, Daniele (CERN) ; Saura Esteban, Francisco Javier (CERN) ; Bottura, Luca (CERN) et al.
Muon production in the multi-TeV muon collider studied by the International Muon Collider Collaboration is planned to be performed with a high-power proton beam interacting with a fixed target. The design of the target area comes with a set of challenges related to the radiation load to front-end equipment. [...]

Progress in the design of the future circular collider FCC-ee interaction region / Boscolo, Manuela (Frascati) ; Frasca, Alessandro (CERN) ; Novokhatski, Alexander (SLAC) ; Ciarma, Andrea (Frascati) ; Lechner, Anton (CERN) ; Ilg, Armin (Zurich U.) ; Di Pasquale, Enrico (Frascati) ; Palla, Fabrizio (INFN, Pisa ; CERN) ; Bosi, Filippo (INFN, Pisa) ; Fransesini, Francesco (Frascati) et al.
We report on the latest developments for the FCC-ee interaction region design that represents a major challenge for the collider, which has to achieve extremely high luminosity over a wide range of centre-of-mass energies. The FCC-ee will host four experimental apparatuses. [...]

Energy deposition and radiation level studies for the FCC-ee experimental insertions / Frasca, Alessandro (CERN ; Liverpool U.) ; Ciarma, Andrea (Frascati) ; Lechner, Anton (CERN) ; Perillo Marcone, Antonio (CERN) ; Humann, Barbara (CERN) ; Järmyr Eriksson, Carl (CERN) ; Welsch, Carsten (Liverpool U.) ; Calzolari, Daniele (CERN) ; Lerner, Giuseppe (CERN) ; Boscolo, Manuela (Frascati) et al.
The Future Circular Collider (FCC) study foresees the construction of a 90.7 km underground ring where, as a first stage, a high-luminosity electron-positron collider (FCC-ee) is envisaged, operating at beam energies from 45.6 GeV (Z pole) to 182.5 GeV (ttbar). In the FCC-ee experimental interaction regions, various physical processes give rise to particle showers that can be detrimental to machine components as well as equipment in the tunnel, such as cables and electronics. [...]

Challenges and mitigation measures for synchrotron radiation on the FCC-ee arcs / Humann, Barbara (CERN) ; Frasca, Alessandro (CERN) ; Lechner, Anton (CERN) ; Järmyr Eriksson, Carl (CERN) ; Valchkova-Georgieva, Fani (Unlisted, CH) ; Bauche, Jeremie (CERN) ; Hofer, Michael (CERN) ; Kersevan, Roberto (CERN) ; Garcia Alia, Ruben (CERN)
In a high-energy circular electron-positron collider like the Future Circular Collider (FCC-ee) at CERN, synchrotron radiation (SR) presents a significant challenge due to the radiation load on collider magnets and equipment in the tunnel like cables, optical fibers, and electronics. The efficiency of the anticipated photon absorbers in the vacuum chambers depends on the operational beam energy, ranging from 45.6 GeV to 182.5 GeV. [...]

FLUKA simulations of neutrino-induced effective dose at a Muon Collider / Lerner, Giuseppe (CERN) ; Frasca, Alessandro (CERN ; Liverpool U.) ; Lechner, Anton (CERN) ; Carli, Christian (CERN) ; Ahdida, Claudia (CERN) ; Manczak, Jerzy (CERN)
During the operation of a muon collider in an underground tunnel, most circulating muons decay into an electron (or positron) and a neutrino-antineutrino pair, resulting in a narrow disk of high-energy neutrinos emitted radially in the collider plane and emerging on the Earth’s surface at distances of several km. Thus, dedicated studies are required to assess any potential radiation protection risks to the public due to the interaction of such neutrinos near the surface. [...]

Collimation performance of the 400MJ LHC beam at 6.8 TeV / Van der Veken, Frederik (CERN) ; Abramov, Andrey (CERN) ; Azzopardi, Gabriella (CERN) ; Broggi, Giacomo (CERN) ; Bruce, Roderik (CERN) ; Cai, Rongrong (CERN) ; D'Andrea, Marco (CERN) ; Dewhurst, K A (CERN) ; Frasca, Alessandro (CERN) ; Hermes, Pascal (CERN) et al.
During the third operational run of the Large Hadron Collider at CERN, starting in 2022, the beam energy was increased to 6.8 TeV and the bunch population is planned to be pushed to unprecedented levels. Already in the first year of operation, beam stored energies up to 400 MJ were achieved. [...]
