Dr. Brian Rebel, Fermilab

The next generation of neutrino oscillation experiments will attempt to measure the mixing between the electron and muon flavors, CP violation in the neutrino sector, and the neutrino mass hierarchy. One of the challenges for these experiments is the separation of background neutral current interactions producing neutral pions from the desired electron neutrino charged current interactions. Liquid argon time projection chamber (LArTPC) detectors offer unparalleled ability to separate these types of interactions, but no large scale LArTPC has been built. Given the advantage of this technology, Fermilab and collaborating institutions are actively pursuing an R&D plan to build a 20 kton scale LArTPC. In this talk I will describe the physics reach of such a LArTPC and the various steps along the path to such a detector.
