Located 2,341 feet beneath the surface, in an old iron mine, the lab is deep enough that particle physics experiments see less than 100,000 times the cosmic radiation than on the surface, allowing sensitive searches for exotic particles like neutrinos and dark matter.
The MINOS neutrino experiment and the CDMS2 dark matter search are the two largest projects supplemented by several smaller experiments taking advantage of low background radiation to search for dark matter, measure neutron background underground, and assay experimental equipment to ensure radiopurity.
Summer visitors take tours of the lab and learn about particle astrophysics, and during the school year field trips are popular with Minnesota science classes.
The only operational deep underground lab in the US. Space and infrastructure available for a wide range of neutrino, dark matter, and low background counting experiments.
