Description
A considerable challenge to the physics potential at a multi-TeV muon collider is the significant amount of beam-induced background (BIB) produced near the interaction region (IR), primarily from muons decaying along the straight section near the IR. BIB mitigation, therefore, is one of the primary drivers of the machine-detector interface (MDI) design. Several strategies have been developed to reduce the quantity of and modify the composition of the BIB, enhancing the ability to discern collision processes of interest from the background. These approaches include fine-tuning the collider lattice design while meeting beam dynamics requirements, incorporating dense shielding structures in the forward regions of the detector, and designing a finely segmented detector with 30-60 ps timing resolution. This presentation will review the dominant sources of BIB, key BIB mitigation strategies, the impact of the resulting BIB on the detector, and promising directions for future work in muon collider MDI optimization.
