                      of dark matter to date, it is natural to wonder whether dark
                      matter couples predominantly to the Standard Model (SM)’s
                      neutrinos. Neutrino interactions (and the possible existence
                      of additional neutrinophilic mediators) are substantially
                      less understood than those of other SM particles, yet this
                      picture will change dramatically in the coming decades with
                      new neutrino sources. One potential new source arises with
                      the construction of a high-energy muon collider (MuCol); due
                      to muons’ instability, a MuCol is a source of high-energy
                      collimated neutrinos. Importantly, since the physics of muon
                      decays (into neutrinos) is very well-understood, this leads
                      to a neutrino flux with systematic uncertainties far smaller
                      than fluxes from conventional high-energy (proton-sourced)
                      neutrino beams. In this work, we study the capabilities of a
                      potential neutrino detector, “MuColν”, placed ∼100 m
                      downstream of the MuCol interaction point. The MuColν
                      detector would be especially capable of searching for a
                      neutrinophilic mediator ϕ through the mononeutrino
                      scattering process νμN→μ+ϕX, exceeding searches from
                      other terrestrial approaches for mϕ in the ∼few MeV- ten
                      GeV range. Even with a 10 kg-yr exposure, MuColν is capable
                      of searching for well-motivated classes of thermal
                      freeze-out and freeze-in neutrino-portal dark matter.},
