Abstract:
I will present the physics motivations and requirements for the large (>300kT) water Cherenkov detector at the DUSEL, including the arguments in support of the proposed size and depth of the detector. I will compare the physics reach of the detector with other existing and proposed experiments world wide. Some information on the status of the DUSEL, the R&D program for the detector, the beam line, the collaboration, and the complementarity between the water Cherenkov detector and a large liquid Argon detector will also be presented.
