Dr. Ray Davis inspects his neutrino detector under construction in the Homestake gold mine. (1965)
A laboratory 4,850 feet underground in the Homestake gold mine in Lead, South Dakota, helped start a revolution in physics.
Dr. Ray Davis installed a neutrino detector in Homestake in 1965. Neutrinos are subatomic particles produced by fusion in stars, and over the course of three decades, the Davis experiment led to the discovery that the neutrinos produced in our sun change type, or "flavor," on their way to earth. The change in flavor meant neutrinos had to have at least a wisp of mass -- a wisp that required a significant change in the Standard Model of how the universe works.

Hundreds attend Neutrino Day 2010
Â
July 10 event draws 600-plus
Lead, S.D. -- Neutrino Day drew about 550 people to the Yates Dry and the Yates Shaft hoist room on a Saturday morning.
Add 65 people for the standing-room-only crowd at Friday’s night’s Science Cafe at the Stampmill and about 30 for an art-and-science lecture downtown on Sunday, and we reached well over 600 people for the third straight year. Lecturers Jaret Heise and John Scheetz of the Sanford Lab, Kara Keeter of BHSU and Tom Durkin of SDSMT each spoke to near-capacity crowds in the old ERT room.
Lead, S.D. -- Dark matter afficianados won't want to miss the Sanford Underground Laboratory's Fourth of July Parade float. It's a salute to the Large Underground Xenon Detector, which will search for dark matter at the 4,850-foot level of the Sanford Lab.
To ensure the technical accuracy of this r…
Lead, S.D. A high-definition videoconference over the ultra-high speed Interet2Â network connected 600 people in a ballroom in Virginia to the 4,850-foot level deep in the Sanford Underground Laboratory at Homestake.Click here to see a webcast of the event, which was on April 28, 2010.
Lead, S.D. -- Sanford Lab personnel and contractors have remodeled a former Homestake warehouse, which will serve as a surface laboratory and assembly facility for a dark-matter detector. The lab includes a clean room, where scientists will assemble and test the Large Underground Xenon dark-matter d…
Monday, July 5; 9 p.m. CDT (8 p.m. MDT) Sanford Lab also on S.D. Public Radio's "Innovation"
LEAD, S.D. -- Gov. Mike Rounds will take television viewers a mile underground to visit with scientists and technicians re-opening the former Homestake gold mine in Lead as a national laboratory.
The Governor is the host of -- "Deep Science: the vision for underground research at Homestake" --Â a 30-minute video that will air on South Dakota Public Television on Monday, July 5, at 9 p.m. CDT (8 p.m. MDT). Viewers will join the Governor for a look at the kinds of research that physicists, geologists and biologists hope to do at South Dakota's first national laboratory.
Three research groups at the Sanford Underground Laboratory at Homestake detected recent earthquakes in Japan, Chile, Haiti and Mexico -- as well as last September's tsunami in the Pacific Ocean. The data illustrate how the Sanford Lab, as the nation's Deep Underground Science and Engineering Labora…
