Description
ArgoNeuT is a small scale (170 liter) Liquid Argon Time Projection Chamber (LArTPC) which collected data at Fermi National Accelerator Laboratory in Batavia, Illinois (2009 2010). ArgoNeuT was located 100 meters underground, upstream of the MINOS near detector, exposed to the on-axis NUMI neutrino beamline. It is an R&D project paving the way for bigger LArTPCs such as MicroBooNE and multi-kiloton scale devices. The detector takes neutrino interactions in the 0.1 to 10 GeV range, providing the first ever low energy neutrino interactions data within a LArTPC. ArgoNeuT provides bubble-chamber-quality images with high quality particle identification through dE/dx that results in excellent background rejection and high sensitivity for detecting rare event types. As an example, ArgoNeuT can observe the CKM-suppressed analog to quasi-elastic scattering where a neutral strange particle is produced instead of a nucleon in the final state. Its ability to ‘see’ the detached vertex of a neutral hyperon decay, makes it stand out among other experiments. There are very few studies on neutral hyperon production via charge current quasi-elastic (CCQE) neutrino interaction. Among other measurements, ArgoNeuT will allow for a study comparing CCQE neutral hyperon production and CCQE neutron production at low energy.
