How an Underground Science Facility Got Off the Ground

In the Black Hills of South Dakota, researchers at the Sanford Underground Research Facility (SURF) — situated a mile below ground—have been seeking out the nature of dark matter and ghostly particles known as neutrinos. Berkeley Lab has played a critical role in establishing, developing, and operating the facility. More>

LUX: The End of an Era

The Large Underground Xenon (LUX) experiment — which started taking data in 2013 — has proven to be the world’s most sensitive dark matter experiment. Housed nearly a mile below ground at the Sanford Lab in South Dakota, LUX is being decommissioned to make room for the larger LUX-ZEPLIN experiment, a next-generation dark matter detector set to begin operating in 2020.

Latest Daya Bay Results: New Limits on Where Sterile Neutrinos May be Hiding

A team of scientists, including Berkeley Lab researchers, working on a neutrino experiment at Daya Bay in China, and a separate team working on the MINOS experiment have released a set of results that limit the possible hiding places for theoretical particles known as sterile neutrinos. These as-yet-undiscovered particles are one of many possible candidates for dark matter. More>
