Abstract

This study presents comparative CP sensitivities for various sets of water Cerenkov and liquid argon detectors combined with various running scenarios associated with DAEdALUS and LBNE neutrino beams at DUSEL. LBNE-only running scenarios show fairly small differences in sensitivity for the various detector combinations. On the other hand, the DAEdALUS-only and DAEdALUS-plus-LBNE running gives significantly better sensitivity for a detector combination that includes at least 200 kt of Gd-doped water Cerenkov detector, exceeding the sensitivity of a Project-X 10 year run. A 300 kt Gd-doped water Cerenkov detector yields the best sensitivity for combined running.
