On July 14, Sanford Underground Research Laboratory in South Dakota hosted Neutrino Day X, the tenth anniversary of Sanford Lab’s free science festival. Nearly 1,500 people from several states and a handful of countries participated in the many different activities.
Fermilab represented the Long-Baseline Neutrino Facility and the Deep Underground Neutrino Experiment, an international flagship experiment hosted by the lab, at the festival.
Enjoy the photos from the day below. And read all about Neutrino Day X from Sanford Lab.
