Muon colliders present a unique opportunity to achieve unprecedented center-of-mass energies in lepton collisions. Unlike electrons, muons are not significantly affected by synchrotron radiation, allowing them to be accelerated and collided at higher energies. Additionally, since muons are elementary particles, issues related to partonic effects are eliminated.
However, the use of muons introduces several significant challenges. The primary concern addressed in this paper is the impact of muon decay products on the collider's components and the experimental background. We also thoroughly examine other background sources, with a focus on incoherent pair production during bunch crossings. To manage the substantial radiation produced, we propose a shielding strategy for the final focusing elements, detailing its implications on the lattice design. For the detectors, we outline a potential shielding component (nozzle) designed to minimize the background that reaches the experiment.
