Searches for dark-matter particles at the GeV mass scale have been
receiving much attention in the last several years, partly motivated
by the failure of direct and indirect searches of heavier candidates
to produce a signal. The SpinQuest dimuon experiment in the 120-GeV
Main-Injector proton beam at Fermilab, currently in the commissioning
stage, is uniquely equipped to search for dark photons and dark Higgs
particles produced in a 5-m long iron beam dump with masses in the
range 0.2 - 10 GeV, running in a parasitic mode. This only requires
a modest upgrade of a displaced-vertex trigger with acceptance for
dark-sector particles decaying into dimuons inside or downstream of
the dump. We discuss the physics reach of such a run, the status,
and some additional future prospects.
