Technical Proposal jointly submitted to SPS-C: arXiv:1230.3432, April 2012

• In the last decade a set of experimental results challenged the 3 framework no one conclusive, but all pointing toward the same direction

M-773) of March 9, 2011Proposal “A comprehensive search for

<<“anomalies>>” from neutrino and anti-neutrino oscillations at large mass differences (m2 ≈ 1eV2) with two LAr–TPC imaging detectors at different distances from the CERN-PS” (SPSC-P-345) of Oct. 14th, 2011;·  

  Proposal “Prospect for Charge Current Neutrino Interactions Measurements at the CERN-PS” with two magnetic spectrometers for measuring CC neutrino interactions (SPSC-P-343) of Oct. 11th, 2011;

Joint Technical proposal: “Search for “anomalies” from neutrino and anti-neutrino oscillations at m2 ≈ 1eV2 with muon spectrometers and large LAr–TPC imaging detectors” (SPSC-P-347) of March 15th, 2012.

NESSiE (Neutrino Experiment with SpectrometerS in Europe) Goal:

Allow charge separation and momentummeasurement of as many muons as possibleescaping from LAr (large statistics ↔ low sin22)

Go as low as possible in muon momentum(low momenta ↔ low m2)

Possibility to also study (NESSiE) internal events(coarser resolution w.r.t. LAr)

Solution: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
