Neutrino CERN-PS Experiment:
Neutrino Experiment with SpectrometerS in
Europe
Technical Proposal jointly submitted to SPS-C: arXiv:1230.3432,
April 2012

1
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
Reactor n-bar anomaly
MiniBooNE n and n-bar
Gallium MCi exposure
Cosmology
2
A conclusive experiment
A coupled system of LAr detector + muon spectrometer for
– Observation of
all reaction channels
(nm, ne; 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)

Produced documentation so far
 Relevant documents sent to SPS Committee by the ICARUS
and NESSiE Collaborations:
a Memorandum from the ICARUS collaboration (SPSC-M773) 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.
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
NESSiE detector concept
NESSiE (Neutrino Experiment with SpectrometerS in Europe)
 Goal:
Dm2
measurement of as many muons as possible
escaping 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)
Statistics
Spectru
n
Allow charge separation and momentum
sin22q
 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
8
Air-core magnet
 New concept for a large
transverse area magnetic field
in air (~40 m2)
 B = 0.15 T
 Power < 2 MW
 To be coupled to a mm detector
(different possibilities under study)
