Description
The Liquid Argon In A Testbeam (LArIAT) experiment is a 0.26 ton active mass Liquid Argon Time Projection Chamber (LArTPC) located at the Fermilab Test Beam Facility. The LArIAT TPC is exposed to a tertiary beam comprised of mostly pions along with a mix of muons, protons, kaons, and electrons in the range ~200 MeV to 2 GeV. The beamline is instrumented with detectors that aid in identification and selection of particle species and momenta. LArIAT will characterize the response of LArTPCs to these known incoming particles, and these data will be used to tune simulations and reconstruction algorithms in support of future LArTPC neutrino experiments. The first inclusive pion interaction cross section measurement ever made on argon will be presented here. This analysis uses data collected during LArIAT’s initial run (Run-I); updates and extensions to the analysis using additional data from Run-II will also be discussed.
