    With the turning of a shovelful of earth a mile underground, a new era in international particle physics research officially began today.

    In a unique groundbreaking ceremony held this afternoon at the Sanford Underground Research Facility in Lead, South Dakota, a group of dignitaries, scientists and engineers from around the world marked the start of construction of a massive international experiment that could change our understanding of the universe. The Long-Baseline Neutrino Facility (LBNF) will house the international Deep Underground Neutrino Experiment (DUNE), which will be built and operated by a group of roughly 1,000 scientists and engineers from 30 countries.

    When complete, LBNF/DUNE will be the largest experiment ever built in the United States to study the properties of mysterious particles called neutrinos. Unlocking the mysteries of these particles could help explain more about how the universe works and why matter exists at all.

    At its peak, construction of LBNF is expected to create almost 2,000 jobs throughout South Dakota and a similar number of jobs in Illinois. Institutions in dozens of countries will contribute to the construction of DUNE components. The DUNE experiment will attract students and young scientists from around the world, helping to foster the next generation of leaders in the field and to maintain the highly skilled scientific workforce in the United States and worldwide.

    The U.S. Department of Energy’s Fermi National Accelerator Laboratory, located outside Chicago, will generate a beam of neutrinos and send them 1,300 kilometers (800 miles) through Earth to Sanford Lab, where a four-story-high, 70,000-ton detector will be built beneath the surface to catch those neutrinos.

    Scientists will study the interactions of neutrinos in the detector, looking to better understand the changes these particles undergo as they travel across the country in less than the blink of an eye. Ever since their discovery 61 years ago, neutrinos have proven to be one of the most surprising subatomic particles, and the fact that they oscillate between three different states is one of their biggest surprises. That discovery began with a solar neutrino experiment led by physicist Ray Davis in the 1960s, performed in the same underground mine that now will house LBNF/DUNE. Davis shared the Nobel Prize in physics in 2002 for his experiment.

    DUNE scientists will also look for the differences in behavior between neutrinos and their antimatter counterparts, antineutrinos, which could give us clues as to why the visible universe is dominated by matter. DUNE will also watch for neutrinos produced when a star explodes, which could reveal the formation of neutron stars and black holes, and will investigate whether protons live forever or eventually decay, bringing us closer to fulfilling Einstein’s dream of a grand unified theory.

    But first, the facility must be built, and that will happen over the next 10 years. Now that the first shovel of earth has been moved, crews will begin to excavate more than 870,000 tons of rock to create the huge underground caverns for the DUNE detector. Large DUNE prototype detectors are under construction at European research center CERN, a major partner in the project, and the technology refined for those smaller versions will be tested and scaled up when the massive DUNE detectors are built.

    This research is funded by the U.S. Department of Energy Office of Science in conjunction with CERN and international partners from 30 countries. DUNE collaborators come from institutions in Armenia, Brazil, Bulgaria, Canada, Chile, China, Colombia, Czech Republic, Finland, France, Greece, India, Iran, Italy, Japan, Madagascar, Mexico, the Netherlands, Peru, Poland, Romania, Russia, South Korea, Spain, Sweden, Switzerland, Turkey, Ukraine, United Kingdom and the United States.

    U.S. Senator John Thune, South Dakota

    “The Long-Baseline Neutrino Facility continues Lead, South Dakota’s, tradition of cutting-edge neutrino research, dating back to physics experiments at the former Homestake Mine in the 1960s. When completed, LBNF and the Deep Underground Neutrino Experiment will attract some of the world’s brightest scientists to South Dakota and push the boundaries of basic research, not to mention support good-paying jobs in the historic mining region of the Black Hills. I look forward to seeing the facility’s completion and the groundbreaking experiments that will be done in the years to come.”

    U.S. Senator Mike Rounds, South Dakota

    “Today’s groundbreaking marks another significant step toward gaining a deeper understanding of the makeup of our universe. It is pretty remarkable that such world-class research continues to develop right here in Lead, South Dakota. When we began the process of securing an underground laboratory at South Dakota’s Homestake gold mine more than a decade ago, we were hopeful that it would lead to major advancements in particle physics and neutrino research. Today, those hopes are turning into reality as the Sanford Underground Research Facility, Fermilab and CERN join together to break ground on the Long-Baseline Neutrino Facility, which will house the Deep Underground Neutrino Experiment. Today is a truly special day, and I thank everyone involved in this collaboration for the years of hard work they’ve put into this project.”
