Abstract
Multi-kton iron detectors can be simultaneously exploited as far detectors for high energy Beta Beams and to determine the atmospheric νμ flux in the multi-GeV range. These measurements can be combined in a highly non trivial manner to improve the sensitivity to the hierarchy of neutrino masses. Considering a Super-SPS based Beta Beam and a 40 kton far detector located â¼700km from the source (CERN to Gran Sasso distance), we demonstrate that even with moderate detector granularities the sign of Îm132 can be determined for θ13 values greater than 4°. © 2008 American Institute of Physics.
