Liquid Argon Neutrino Detector Development at Fermilab

Liquid Argon Time Projection Chambers (LAr TPCs) are ideally suited for the study of neutrino interactions thanks to their combination of scalability and precision detection capability. In this talk I will highlight work in the development of this technology at Fermilab, focusing on the details of the ArgoNeuT project and the MicroBooNE experiment. ArgoNeuT is a 175 liter LArTPC that was recently operated in the NuMI beamline, and MicroBooNE is a 90 ton LArTPC that will begin operations in the Booster neutrino beam beginning in 2013. I will conclude with preliminary ideas for the ultimate LArTPC experiment that could be conducted at the Deep Underground Science and Engineering Laboratory (DUSEL) in South Dakota.
