Title: Simulation of backgrounds in detectors and energy deposition in superconducting magnets at μ+μ− colliders
Abstract: A calculational approach is described to study beam induced radiation effects in detector and storage ring components at high‐energy high‐luminosity μ+μ− colliders. The details of the corresponding physics process simulations used in the MARS code are given. Contributions of electromagnetic showers, synchrotron radiation, hadrons and daughter muons to the background rates in a generic detector for a 2×2 TeV μ+μ− collider are investigated. Four configurations of the inner triplet and a detector are examined for two sources: muon decays and beam halo interactions in the lattice elements. The beam induced power density in superconducting magnets is calculated and ways to reduce it are proposed.
