From the mid-1960s to the mid-1990s, Dr. Ray Davis Jr. operated his solar neutrino experiment on the 4850 Level of Homestake Mine, earning a Nobel Prize in Physics. Today, the Sanford Underground Research Facility (Sanford Lab) houses big physics experiments, as well as other experiments in biology, geology and engineering, nearly a mile underground in the former gold mine.
On Monday, January 30, the public is invited to a free presentation with Mike Headley, executive director of the South Dakota Science and Technology Authority and Sanford Lab, and Jaret Heise, science director. In “Deep Talks on the Road: Big Science at Sanford Lab,” the two will discuss the impacts that experiments housed deep underground have on education and the economy in South Dakota. The event will be held at the Hill City High School, 341 Main St., at 7 p.m.

“We’re on the verge of constructing one of the largest international mega-science projects to ever be developed on U.S. soil to study the mysteries of neutrinos,” said Headley in reference to the Long Baseline Neutrino Facility and associated Deep Underground Neutrino Experiment (LBNF/DUNE). Work on facilities that will house the next-generation dark matter detector also are underway. The LUX-ZEPLIN (LZ) experiment will be the largest and most sensitive dark matter detector in the world.
“These experiments and several others have been used to enhance STEM education for K-12 schools throughout South Dakota,” Headley said. Sanford Lab’s Education and Outreach department has created six assembly programs and six curriculum modules that have reached more than 13,000 students throughout the state since introduced in 2015. The department also holds teacher workshops and hosts dozens of field trips yearly.

The experiments also contribute to the state’s economy. “Big Science at Sanford Lab” will look at the economic impacts current experiments have had on the state, and feature a report that was done on the economic impact of the LBNF/DUNE project, including projected spending and jobs creation. “This project has a tremendous potential to boost the economy of South Dakota,” Headley said.
Headley has over 24 years of engineering and management experience. Before coming to Sanford Lab in 2008, Headley served in various roles at the U.S. Geological Survey (USGS) Earth Resources Observation and Science Center (EROS) in Sioux Falls, S.D. Headley earned his bachelor’s degree from South Dakota State University and an MBA from Loyola Marymount University. He served in the U.S. Air Force for six years.

Heise also joined the Sanford Lab team in 2008 after working for several years with the Sudbury Neutrino Observatory (SNO), an underground research facility in Canada. The SNO experiment, which helped solve Davis’ solar neutrino problem, won a share of the 2015 Nobel Prize in Physics. Heise, who also held a postdoctoral position at Los Alamos National Lab, earned his Ph.D. in particle astrophysics from the University of British Columbia in Vancouver, Canada.
Deep Talks on the Road is a lecture series created by Sanford Lab and held in several locations throughout the state.
