2 In the last decade a set of experimental results challenged the 3 framework  no one conclusive, but all pointing toward the same direction Experimental motivations 2 LSND MiniBooNE and -bar Reactor -bar anomaly Cosmology Gallium MCi exposure Alessandro Bertolin / Luca Stanco - CdS Padova

3 A coupled system of LAr detector + muon spectrometer for –Observation of all reaction channels ( , e ; CC, NC) through the unique LAr-TPC imaging capabilities –Charge separation and muon momentum extension with a magnetized iron spectrometer –Different sites near (300 m) + far (1600 m) A conclusive experiment 3 Alessandro Bertolin / Luca Stanco - CdS Padova

4 Where: CERN North Area 4  100 GeV primary beam fast extracted from SPS  Target station next to TCC2  Decay pipe: L =100 m, ø = 3 m  Beam dump: 15 m of Fe with graphite core, followed by μ stations  Neutrino beam angle: pointing upwards, at -3m in the far detector, ~5 mrad slope Alessandro Bertolin / Luca Stanco - CdS Padova
