  1. SPECTROMETER(S) Prospects for a New Neutrino CERN-PS Experiment: NESSiE Neutrino Experiment with SpectrometerSin Europe Technical Proposal jointly submitted to SPS-C: arXiv:1230.3432, April 2012 Alessandro Bertolin / Luca Stanco - CdS Padova

  2. Experimental motivations • In the last decade a set of experimental results challenged the 3 n framework no one conclusive, but all pointing toward the same direction LSND MiniBooNE n and n-bar Gallium MCi exposure Cosmology Reactor n-bar anomaly

  3. A conclusive experiment A coupled system of LAr detector + muon spectrometer for • Observation ofall reaction channels(nm, ne; CC, NC)through the uniqueLAr-TPC imagingcapabilities • Charge separationand muon momentumextension with amagnetized ironspectrometer • Different sitesnear (300 m) + far (1600 m)

  4. Where: CERN North Area • 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

  6. Produced documentation so far • Relevant documents sent to SPS Committee by the ICARUS and NESSiE Collaborations: • a Memorandum from the ICARUS collaboration (SPSC-M-773) of March 9, 2011 • Proposal “A comprehensive search for <<“anomalies>>” from neutrino and anti-neutrino oscillations at large mass differences (Dm2 ≈ 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 Dm2 ≈ 1eV2 with muon spectrometers and large LAr–TPC imaging detectors”(SPSC-P-347) of March 15th, 2012.

  7. Beam Studies at SPS • 100 GeV proton, Fast Extraction (10.5 ms), Luminosity as at CNGS (conservative) On-Axis !! CC muons CC electrons Scenario defined for DATA Taking: 2 years of anti-n followed by 1 year n

  8. NESSiE detector concept NESSiE (Neutrino Experiment with SpectrometerS in Europe) • Goal: • Allow charge separation and momentummeasurement of as many muons as possibleescaping from LAr (large statistics ↔ low sin22q) • Go as low as possible in muon momentum(low momenta ↔ low Dm2) • Possibility to also study (NESSiE) internal events(coarser resolution w.r.t. LAr) • Solution: • Air-core magnets for low momentum muons escaping from LAr(Em < 0.5 GeV/c in NESSiE ↔ En < 1 GeV in LAr) • Downstream massive iron dipolar magnets for higher momenta extension Statistics Dm2 Spectrun sin22q

  9. Air-core magnet • New concept for a largetransverse area magnetic fieldin air (~40 m2) • B = 0.15 T • Power < 2 MW • To be coupled to a mm detector(different possibilities under study)

  12. NESSiE time schedule • Physics proposal submitted to SPSC in Oct 2011 [arXiv: 1111.2242v1] • In the meanwhile: • Request to switch PS ↔ SPS • Joint technical proposal submitted to SPSC in March 2012 [arXiv:1203.3432] • From green-light, we expect 3 years of prototyping and construction run in 2016
