Dynamics of decay electrons and synchrotron radiation in a TeV muon collider

The decay electrons (and positrons) in a TeV muon collider present major challenges as heat loads to the superconducting magnets and as sources of Bethe-Heitler muon pairs that form streaming backgrounds in the detectors. If the dipoles are configured so as to accommodate a vacuum gap extending in the horizontal midplane between the coils, it is possible to channel both the decay electrons and the synchrotron radiation out of the magnet and intercept them at significant angle at the exit aperture. In this way both the heat load and the muon halo problems are mitigated
