Design of the Muon Collider Lattice: Present Status

We discuss a preliminary design for a high luminosity 4 TeV center of mass μ+μ- collider ring. A possible lattice for a muon collider has been described. The design satisfies most of the collider requirements, although it is not fully realistic. Error and tolerance analyses are yet to be performed as well as tracking to determine the dynamic aperture and achievable luminosity. In order to make the final-focus design realistic, drift spaces must be introduced between all magnet elements, and the lengths of the insertions will have to be increased in order to achieve the required dispersion values in the sextupoles with reasonable dipole fields
