Part 4/9:
Initially conceived as a U.S.-centric project, DUNE evolved into an international endeavor beginning in 2015, with peer-reviewed support and broad collaboration from particle physicists worldwide. The project's framework involves two principal locations across approximately 800 miles—a particle accelerator positioned at Fermilab near Chicago that generates a concentrated beam of neutrinos, and a vast underground detection facility in South Dakota. This strategic separation is designed to allow for distinctive observation of neutrino oscillations as these particles traverse the intervening distance.
