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.

Why choose liquid argon for DUNE detectors?

In its quest to understand why matter exists, the flagship neutrino experiment hosted by Fermilab is constructing an enormous next-generation liquid-argon-based detector a mile underground. The Deep Underground Neutrino Experiment is building on the successes of previous liquid-argon experiments, promising measurements of unprecedented precision over a wide range of energies that will bring significant new insights into the nature of the universe.

Precision and ingenuity drive construction of DUNE detector components

Particle physics experiments use detectors that are intricate, sophisticated devices for learning about the origins and composition of the universe. The Deep Underground Neutrino Experiment is designed to tackle one of physics’ biggest mysteries — matter-antimatter asymmetry in the universe — by studying neutrinos. Production of Anode Plane Assemblies, detector components that will allow DUNE to achieve exquisite measurement precision, requires skilled technicians, a cleverly designed machine and an incredible attention to detail.
