Advanced assessment of beam-induced background at a muon collider

Abstract Renewed international interest in muon colliders motivates the continued investigation of impacts beam-induced background on detector performance. This continues effort initiated by Muon Accelerator Program and carried out until 2017. The from decays directly performance must be mitigated optimizing overall machine design, with particular attention paid to interface region. In order produce events study their characteristics coordination collider optimization, a flexible simulation approach is needed. To achieve this goal we have chosen utilize combination LineBuilder Monte Carlo FLUKA codes. We report results studies these tools obtained for 1.5 TeV center mass energy configuration. Good agreement previous simulations using MARS15 code demonstrates that our choice meet accuracy requirements perform future optimization designs.
