ArgoNeuT hits a home run with measurements of neutrinos in liquid argon

A negative muon and positive pion candidate event in ArgoNeuT. The figure shows the 2-D projections in the two wire planes. The color of the track respects the charge read by the wire planes, wire by wire.

The ArgoNeuT experiment was the first ever to make cross-section measurements of neutrino and antineutrino (the neutrino’s antimatter counterpart) interactions resulting in a muon, a charged pion and any number of nucleons in the final state using argon as the target.

Identifying lower-energy neutrinos with a liquid-argon particle detector


This is a visual display of an ArgoNeuT event showing a long trail left behind by a high energy particle traveling through the liquid argon accompanied by small blips, indicated by the arrows, caused by low energy particles.

The ArgoNeuT experiment recently demonstrated for the first time that a particular class of particle detector — those that use liquid argon — can identify signals in an energy range that particle physicists call the “MeV range.” It’s the first substantive step in confirming that researchers will be able to detect a wide energy range of neutrinos — even those at the harder-to-catch, lower energies — with the international Deep Underground Neutrino Experiment, or DUNE, hosted by Fermilab. DUNE is scheduled to start up in the mid-2020s.
