Fermilab marks 70 years of neutrino science and leads next-generation experiment

As Fermilab commemorates 70 years since the discovery of the neutrino at the Savannah River Site in the United States, the lab also celebrates its multiple generations of pioneering neutrino research. Today, Fermilab is building the next era of neutrino discovery through the development of the world-leading Deep Underground Neutrino Experiment.

Fermilab’s Neutrino Physics Center hosts inaugural DUNE Data Analysis School

Fermilab hosted the inaugural DUNE Data Analysis School, organized through the lab’s Neutrino Physics Center. The school brought together early-career researchers for intensive training in the software and analysis tools needed to perform physics analyses for the upcoming Deep Underground Neutrino Experiment. The program marks a major step in preparing the scientific workforce for DUNE and is expected to become a recurring training initiative.

This graphic shows the engineering design model of the underground DUNE near detector hall. The neutrino beam enters from the right. The liquid-argon time projection chamber (labeled ND-LAr) is the first to encounter the neutrino beam. Directly behind it sits the muon spectrometer, shown in blue and green. Both can move off the beam axis (toward the upper right) to sample different neutrino energies. The third component, the beam monitor at the farthest end of the hall, depicted in yellow and blue, stays in place on axis in the beam. Credit: DUNE Collaboration

DUNE will use liquid-argon time projection chamber technology both near and far

The Deep Underground Neutrino Experiment’s innovative hybrid near detector will be a game changer. An active prototyping program over the last few years has been refining and validating the design of this smaller detector’s key element, a liquid-argon time projection chamber, and the data analysis tools and methods that go with it.
