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. [...]

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. [...]

Neutrino generated radiation from a high energy muon collider

Muons circulating in a muon collider decay and generate neutrinos within a small solid angle, which reach the earth’s surface. One of the challenges of a high energy muon collider is to ensure that showers created by such neutrinos interacting close to the earth’s surface result in very low radiation levels. [...]

Radiation shielding studies for superconducting magnets in multi-TeV muon colliders

Circular muon colliders provide the potential to explore center-of-mass energies at the multi-TeV scale within a relatively compact footprint. Because of the short muon lifetime, only a small fraction of stored beam particles will contribute to the physics output, while most of the muons will decay in the collider ring. [...]

Transverse impedance and beam stability studies for the muon collider ring

In the framework of the International Muon Collider Collaboration, a 10 TeV muon collider ring is being studied, with the option of an intermediate 3 TeV collider stage. The decay of high-energy muons represents a great challenge in terms of heat load management and radiation shielding for the superconducting magnets of the collider ring. [...]

Among the various future lepton colliders under study, muon colliders offer the prospect of reaching the highest collision energies. Despite the promising potential of a multi-TeV muon collider, the short lifetime of muons poses a severe technological challenge for the collider design. [...]

Validation of energy deposition simulations for proton and heavy ion losses in the CERN Large Hadron Collider

Monte Carlo shower simulations are essential for understanding and predicting the consequences of beam losses in high-energy proton and ion colliders. Shower simulations are routinely used at CERN for estimating the beam-induced energy deposition, radiation damage, and radioactivity in the Large Hadron Collider (LHC). [...]

Transverse Coherent Instability Studies for the High-Energy Part of the Muon Collider Complex

The International Muon Collider Collaboration (IMCC) is studying a 3 TeV center-of-mass muon collider ring, as well as a possible next stage at 10 TeV. Muons being 200 times heavier than electrons, limitations from synchrotron radiation are mostly suppressed, but the muon decay drives the accelerator chain design. [...]
