Description
The electron–positron Future Circular Collider (FCC-ee) is a proposed high-energy lepton collider designed to achieve unprecedented luminosity and precision in the study of fundamental particle physics. To fully exploit this potential, it is crucial to control beam-induced experimental backgrounds to ensure safe operation and optimal detector performance. This is particularly challenging due to the complex operational requirements; for example the top-up injection process that generates unavoidable losses at each injection while detectors are taking data. The present baseline scheme foresees a fast bump in the injection region that affects the full circulating beam, leading to beam-halo losses. In this paper, we study these losses, from their sources up to the detector using a multi-step simulation framework, employing multi-turn tracking followed by Monte-Carlo shower studies and detector occupancy analyses, to evaluate their potential impact on experimental detector performance.
