Description
Circular muon colliders offer the exciting potential to collide lepton beams at previously unattained center-of-mass energies. However, a notable technological challenge arises due to the continuous decay of stored muons. This decay introduces significant complexities for both collider and detector design. The secondary radiation fields generated by the decay electrons and positrons can seriously hinder detector performance and may limit the lifespan of its components. Consequently, muon colliders require a sophisticated interaction region design, which combines custom detector shielding with the detector envelope and the final focus system.
Here, we present design studies for the machine-detector interface and quantify the resulting beam-induced background at 10 TeV center-of-mass energy. Starting from the optics and shielding design developed by the MAP collaboration for a 1.5 TeV collider, we propose an initial interaction region layout for a 10 TeV collider. Specifically, we investigate how choices in lattice and shielding design impact the distribution of secondary particles entering the detector. These results are vital for evaluating detector performance and conducting studies on radiation damage.
