NESSiE (Neutrino Experiment with SpectrometerS in Europe) lGoal:  Allow charge separation and momentum measurement of as many muons as possible escaping from LAr (large statistics ↔ low sin 2 2  )  Go as low as possible in muon momentum (low momenta ↔ low  m 2 )  Possibility to also study (NESSiE) internal events (coarser resolution w.r.t. LAr) lSolution:  Air-core magnets for low momentum muons escaping from LAr (E  < 0.5 GeV/c in NESSiE ↔  E  < 1 GeV in LAr)  Downstream massive iron dipolar magnets for higher momenta extension NESSiE detector concept 8 m2m2 sin 2 2  Statistics Spectru n Alessandro Bertolin / Luca Stanco - CdS Padova
