In addition to the vertical distance from the surface, often referred to as the facility's "overburden" or "vertical overburden," the structure, density, and makeup of the earth above the laboratory impact the penetration capability of cosmic rays. A facility's depth is therefore "normalized" by measuring the actual cosmic ray intensity at that facility and then expressing its depth in terms of meters of water equivalent (m.w.e.)

This facility was developed in 1980 and installed in an abandoned iron mine in Minnesota. The underground structures include the 1,400 m2 principal laboratory space, which hosts a dark matter experiment and a low-background counting facility; a small, high-purity copper fabrication facility; and the 560 m2 main injector neutrino oscillation search (MINOS)

LNGS is operated as an international laboratory with an international scientific committee, appointed by INFN, which advises the director on the suite of experiments for the facility. The scientific program includes these: • The search for τ neutrino appearance on the μ neutrino beam emitted from the Large Hadron Collider of the European Center for Nuclear Research (CERN)
