                                    <b>Abstract: </b>A clear outcome of
                                    Snowmass 2021 was the community
                                    support for R&amp;D towards a future
                                    muon collider. We propose a new beam
                                    dump experiment at a future
                                    TeV-scale muon collider, and the
                                    demonstrator facilities along the
                                    way. A beam dump would be an
                                    economical and effective way to
                                    increase the discovery potential of
                                    the collider complex in a
                                    complementary regime. In this work
                                    we consider vector models such as
                                    the dark photon and Lμ−Lτ gauge
                                    boson as new physics candidates and
                                    explore which novel regions of
                                    parameter space can be probed with a
                                    muon beam dump. We find that, at the
                                    full center of mass energies, for
                                    the dark photon model, we gain
                                    sensitivity in the moderate mass
                                    (MeV - GeV) range at both higher and
                                    lower couplings compared to existing
                                    and proposed experiments, and gain
                                    access to previously untouched areas
                                    of parameter space of the Lμ−Lτ
                                    model. In this talk, we will also
                                    cover the basics towards the
                                    feasibility of a muon collider, as
                                    well as the physics potential at
                                    various demonstrator facilities on
                                    the way to R&amp;D for the full 10+
                                    TeV collider.<br>
