Abstract:

Liquid Argon Time Projection Chambers are precision neutrino detectors which appear scalable to very large volumes. This combination makes them very promising detectors for long baseline neutrino oscillation physics. Their fine-grained tracking and total absorption calorimetry capabilities translate to sensitivity to neutrino oscillation physics significantly better than conventional detection techniques. Recently, interest in these detectors in the US has grown, and a program to scale these detectors to the large sizes needed for long baseline physics has come into focus. This program, from the test stand scale to a large experiment at DUSEL, will be described.
