Angra Neutrino Project: Status And Plans

We present the status and plans of the Angra Project, a new nuclear reactor neutrino oscillation experiment, proposed to be built in Brazil at the Angra dos Reis nuclear reactor complex. This experiment is aimed to measure θ13, the last unknown of the three neutrino mixing angles. Combining a high luminosity design, very low background from cosmic rays and careful control of systematic errors at the 1% level, we propose a high sensitivity multi-detector experiment, able to reach a sensitivity to antineutrino disappearance down to sin2 2θ13 = 0.006 in a three years running period, improving present limits constrained by the CHOOZ experiment by more than an order of magnitude. © 2006 Elsevier B.V.
