A physics Landmark
Sanford Lab is a physics landmark. In 1965, Dr. Ray Davis, a chemist from Brookhaven National Laboratory, built his solar neutrino experiment on the 4850 Level of Homestake Mine. His search for the elusive particle worked, but something was missing. He found only one-third of the neutrinos predicted, which led to the Solar Neutrino Problem and caused a flurry in the scientific world. Finally, in the late 1990s, scientists at SNOlab in Canada, discovered that neutrinos oscillate, or change, as they travel through space. Davis’s experiment only detected one kind. He received the Nobel Prize in Physics in 2002 for his research.
Despite centuries of study and research, we know very little about the universe in which we live. How did we get here? Why is there something instead of nothing? How does our universe actually work? Scientists are seeking answers to these questions and more. It turns out Sanford Lab is the perfect place to find them. Sheltered by nearly a mile of rock, physics experiments find protection from cosmic rays that can interfere with their results.
In the quiet of the 4850 Level, the Large Underground Xenon (LUX) experiment is searching for dark matter; the MAJORANA collaboration is trying to determine whether neutrinos are their own antiparticles; and CASPAR (Compact Accelerator System for Performing Astrophysical Research) is studying what happens in stars when they die.
Several other experiments in biology, engineering, and geology are housed at Sanford Lab as well. One experiment is developing a laser scanner that will be used to search for life on Mars, while another monitors the movement of rock in underground experiments. Future experiments include second-generation dark matter detectors and the Deep Underground Neutrino Experiment (DUNE), which is trying to understand how—and why—neutrinos oscillate, or change flavors, as they travel through space. The experiment will shoot a beam of neutrinos 800 miles through the earth from Fermilab near Chicago to Sanford Lab.
South Dakota’s undergraduate and graduate students benefit from their proximity to the lab—some are part of the experiment collaborations, while others receive internships in engineering, science and communications. Additionally, the Black Hills State University Underground Campus will house up to nine low-background counters and a clean room. The campus will serve students from across the state, giving them space to do their own research projects deep underground.
The Science of Food & Wine
Please join us Friday, February 15, 2019 at 6pm for this informative and fun evening! Dave from Cheyenne Crossing and Kara from Firehouse Wine Cellars will both be teaching about the chemistry involved in cooking and wine making, plus giving suggestions on wine pairing. The menu includes Shrimp du Jon, Martha’s Vineyard Salad, Beef & Pork w/white marinara & tomatoes, and fruit cobbler. All courses come with a delicious wine:) Cost is $25 per person and seating is limited. Call 605-584-3110 to reserve your spot!Find Out More
