A mile underground in South Dakota, construction crews have worked diligently to carve out an extensive network of caverns and tunnels that one day will house a huge neutrino experiment. Their efforts have paid off: With almost 400,000 tons of rock extracted from the earth, the excavation has reached the halfway point.

A new 20,000-pound particle detection system built for a neutrino experiment will be transported 3 miles across the Fermilab campus today. About the size of a small house, it will be the heart of the Short-Baseline Near Detector at Fermilab.

From the Big Think, October 7, 2022: High-energy particles can collide with others, producing showers of new particles that can be seen in a detector. By reconstructing the energy, momentum, and other properties of each one, we can determine what initially collided and what was produced in this event

From Physics Today, July 2022: Anne Heavey, senior technical editor at Fermilab describes how teams from around the world are developing and constructing detector components for the world’s largest cryogenic particle detector, the Deep Underground Neutrino Experiment (DUNE).
