ArgoNeuT, a liquid argon time projection chamber in a low energy neutrino beam

TL;DR

ArgoNeuT is a pioneering liquid argon time projection chamber deployed in a low energy neutrino beam at Fermilab, enabling new measurements of neutrino interactions on argon at around 3 GeV.

Contribution

It is the first LArTPC in a low energy neutrino beam and the second ever in a neutrino beam, providing valuable data for neutrino physics.

Findings

First LArTPC in low energy neutrino beam

Successful operation of a 169 L active volume TPC

Preparation for measuring neutrino-argon cross sections

Abstract

ArgoNeuT (Argon Neutrino Test), a NSF/DOE project at Fermilab, is the first LArTPC to go in a low energy neutrino beam and just the second LArTPC to go in a neutrino beam ever. ArgoNeuT sits just upstream of the on-axis MINOS near detector in the NuMI beamline, about 1 km from the target station and 100 m underground. The detector features a 47X40X90 cm (169 L) active volume TPC with a fully contained recirculation and purification system. Among other physics, ArgoNeuT will measure the charged-current quasi-elastic (anti-) neutrino cross section on argon at an energy of ~3 GeV.
