  The former Homestake gold mine in Lead, South Dakota, has been transformed
into a dedicated facility to pursue underground research in rare-process
physics, as well as offering unique research opportunities in other
disciplines. The Sanford Underground Research Facility (SURF) includes two main
campuses at the 4850-foot level (4300 m.w.e.) -- the Davis Campus and the Ross
Campus -- that host a range of significant physics projects: the LUX dark
matter experiment, the MAJORANA DEMONSTRATOR neutrinoless double-beta decay
experiment and the CASPAR nuclear astrophysics accelerator. Furthermore, the
BHUC Ross Campus laboratory dedicated to critical material assays for current
and future experiments has been operating since Fall 2015. Research efforts in
biology, geology and engineering have been underway at SURF for 10 years and
continue to be a strong component of the SURF research program. Plans to
accommodate future experiments at SURF are well advanced and include
geothermal-related projects, the next generation direct-search dark matter
experiment LUX-ZEPLIN (LZ) and the Fermilab-led international Deep Underground
Neutrino Experiment (DUNE) at the Long Baseline Neutrino Facility (LBNF). SURF
is a dedicated research facility with significant expansion capability, and
applications from other experiments are welcome.
