ABSTRACT: The EUROnu project has studied three possible options for future, high
intensity neutrino oscillation facilities in Europe. The first is a Super Beam,
in which the neutrinos come from the decay of pions created by bombarding
targets with a 4 MW proton beam from the CERN High Power Superconducting Proton
Linac. The far detector for this facility is the 500 kt MEMPHYS water
Cherenkov, located in the Fr\'ejus tunnel. The second facility is the Neutrino
Factory, in which the neutrinos come from the decay of {\mu}+ and {\mu}- beams
in a storage ring. The far detector in this case is a 100 kt Magnetised Iron
Neutrino Detector at a baseline of 2000 km. The third option is a Beta Beam, in
which the neutrinos come from the decay of beta emitting isotopes, in
particular 6He and 18Ne, also stored in a ring. The far detector is also the
MEMPHYS detector in the Fr\'ejus tunnel. EUROnu has undertaken conceptual
designs of these facilities and studied the performance of the detectors. Based
on this, it has determined the physics reach of each facility, in particular
for the measurement of CP violation in the lepton sector, and estimated the
cost of construction. These have demonstrated that the best facility to build
is the Neutrino Factory. However, if a powerful proton driver is constructed
for another purpose or if the MEMPHYS detector is built for astroparticle
physics, the Super Beam also becomes very attractive.

ABSTRACT: This paper describes the performance and sensitivity to neutrino mixing
parameters of a Magnetised Iron Neutrino Detector (MIND) at a Neutrino Factory
with a neutrino beam created from the decay of 10 GeV muons. Specifically, it
is concerned with the ability of such a detector to detect muons of the
opposite sign to those stored (wrong-sign muons) while suppressing
contamination of the signal from the interactions of other neutrino species in
the beam. A new more realistic simulation and analysis, which improves the
efficiency of this detector at low energies, has been developed using the GENIE
neutrino event generator and the GEANT4 simulation toolkit. Low energy neutrino
events down to 1 GeV were selected, while reducing backgrounds to the $10^{-4}$
level. Signal efficiency plateaus of ~60% for $\nu_\mu$ and ~70% for
$\bar{\nu}_\mu$ events were achieved starting at ~5 GeV. Contamination from the
$\nu_\mu\rightarrow \nu_\tau$ oscillation channel was studied for the first
time and was found to be at the level between 1% and 4%. Full response matrices
are supplied for all the signal and background channels from 1 GeV to 10 GeV.
The sensitivity of an experiment involving a MIND detector of 100 ktonnes at
2000 km from the Neutrino Factory is calculated for the case of $\sin^2
2\theta_{13}\sim 10^{-1}$. For this value of $\theta_{13}$, the accuracy in the
measurement of the CP violating phase is estimated to be $\Delta
\delta_{CP}\sim 3^\circ - 5^\circ$, depending on the value of $\delta_{CP}$,
the CP coverage at $5\sigma$ is 85% and the mass hierarchy would be determined
with better than $5\sigma$ level for all values of $\delta_{CP}$.

ABSTRACT: A measurement of the double-differential cross-section for the production of charged pions in proton–tantalum collisions emitted
at large angles from the incoming beam direction is presented. The data were taken in 2002 with the HARP detector in the T9
beam line of the CERN PS. The pions were produced by proton beams in a momentum range from 3GeV/c to 12GeV/c hitting a tantalum target with a thickness of 5% of a nuclear interaction length. The angular and momentum range covered
by the experiment (100MeV/c ≤p< 800MeV/c and 0.35rad ≤θ< 2.15rad) is of particular importance for the design of a neutrino factory. The produced particles were
detected using a small-radius cylindrical time projection chamber (TPC) placed in a solenoidal magnet. Track recognition,
momentum determination and particle identification were all performed based on the measurements made with the TPC. An elaborate
system of detectors in the beam line ensured the identification of the incident particles. Results are shown for the double-differential
cross-sections d2σ/dpdθ at four incident proton beam momenta (3GeV/c, 5GeV/c, 8GeV/c and 12GeV/c). In addition, the pion yields within the acceptance of typical neutrino factory designs are shown as a function of beam
momentum. The measurement of these yields within a single experiment eliminates most systematic errors in the comparison between
rates at different beam momenta and between positive and negative pion production.

ABSTRACT: The International Design Study for the Neutrino Factory (the IDS-NF) was
established by the community at the ninth "International Workshop on Neutrino
Factories, super-beams, and beta- beams" which was held in Okayama in August
2007. The IDS-NF mandate is to deliver the Reference Design Report (RDR) for
the facility on the timescale of 2012/13. In addition, the mandate for the
study [3] requires an Interim Design Report to be delivered midway through the
project as a step on the way to the RDR. This document, the IDR, has two
functions: it marks the point in the IDS-NF at which the emphasis turns to the
engineering studies required to deliver the RDR and it documents baseline
concepts for the accelerator complex, the neutrino detectors, and the
instrumentation systems. The IDS-NF is, in essence, a site-independent study.
Example sites, CERN, FNAL, and RAL, have been identified to allow site-specific
issues to be addressed in the cost analysis that will be presented in the RDR.
The choice of example sites should not be interpreted as implying a preferred
choice of site for the facility.

ABSTRACT: We propose an EASY (Electroluminescent ApparatuS of high Yield) and SOFT
(Separated Optimized FuncTion) time-projection chamber for the NEXT experiment,
that will search for neutrinoless double beta decay (bb0nu) in Xe-136. Our
experiment must be competitive with the new generation of bb0nu searches
already in operation or in construction. This requires a detector with very
good energy resolution (<1%), very low background con- tamination (1E-4
counts/(keV \bullet kg \bullet y)) and large target mass. In addition, it needs
to be operational as soon as possible. The design described here optimizes
energy resolution thanks to the use of proportional electroluminescent
amplification (EL); it is compact, as the Xe gas is under high pressure; and it
allows the measurement of the topological signature of the event to further
reduce the background contamination. The SOFT design uses different sensors for
tracking and calorimetry. We propose the use of SiPMs (MPPCs) coated with a
suitable wavelength shifter for the tracking, and the use of radiopure
photomultipliers for the measurement of the energy and the primary
scintillation needed to estimate the t0. This design provides the best possible
energy resolution compared with other NEXT designs based on avalanche gain
devices. The baseline design is an Asymmetric Neutrino Gas EL apparatus
(ANGEL), which was already outlined in the NEXT LOI. ANGEL is conceived to be
easy to fabricate. It requires very little R&D and most of the proposed
solutions have already been tested in the NEXT-1 prototypes. Therefore, the
detector can be ready by 2013. In this Conceptual Design Report (CDR) we
discuss first the physics case, present a full design of the detector, describe
the NEXT-1 EL prototypes and their initial results, and outline a project to
build a detector with 100 kg of enriched xenon to be installed in the Canfranc
Underground Laboratory in 2013.

The data were taken with the large acceptance HARP detector in the T9 beam line of the CERN Proton Synchrotron. Incident particles were identified by an elaborate system of beam detectors and impinged on a target of 5% of a nuclear interaction length. The tracking and identification of the produced particles was performed using the forward spectrometer of the HARP experiment. Results are obtained for the double-differential cross-sections mainly at four incident beam momenta (3,5,8, and 12 GeV/c).

ABSTRACT: The HARP Collaboration has presented measurements of the double-differential π± production cross section in the range of momentum 100 MeV/c⩽p⩽800 MeV/c and angle 0.35 rad⩽θ⩽2.15 rad with proton beams hitting thin nuclear targets. In many applications the extrapolation to long targets is necessary. In this article the analysis of data taken with long (one interaction length) solid cylindrical targets made of carbon, tantalum, and lead is presented. The data were taken with the large-acceptance HARP detector in the T9 beam line of the CERN proton synchrotron. The secondary pions were produced by beams of protons with momenta of 5, 8, and 12GeV/c. The tracking and identification of the produced particles were performed using a small-radius cylindrical time projection chamber placed inside a solenoidal magnet. Incident protons were identified by an elaborate system of beam detectors. Results are obtained for the double-differential yields per target nucleon d2σ/dpdθ. The measurements are compared with predictions of the MARS and GEANT4 Monte Carlo simulations.

ABSTRACT: This report summarises the conclusions from the detector group of the International Scoping Study of a future Neutrino Factory and Super-Beam neutrino facility. The baseline detector options for each possible neutrino beam are defined as follows: A very massive (Megaton) water Cherenkov detector is the baseline option for a sub-GeV Beta Beam and Super Beam facility. There are a number of possibilities for either a Beta Beam or Super Beam (SB) medium energy facility between 1–5 GeV. These include a totally active scintillating detector (TASD), a liquid argon TPC or a water Cherenkov detector. A 100 kton magnetized iron neutrino detector (MIND) is the baseline to detect the wrong sign muon final states (golden channel) at a high energy (20–50 GeV) neutrino factory from muon decay. A 10 kton hybrid neutrino magnetic emulsion cloud chamber detector for wrong sign tau detection (silver channel) is a possible complement to MIND, if one needs to resolve degeneracies that appear in the δ-θ13 parameter space.

ABSTRACT: In the HARP experiment the large-angle spectrometer is using a cylindrical TPC as
main tracking and particle identification detector. The momentum scale of reconstructed tracks
in the TPC is the most important systematic error for the majority of kinematic bins used for
the HARP measurements of the double-differential production cross-section of charged pions in
proton interactions on nuclear targets at large angle. The HARP TPC operated with a number of
hardware shortfalls and operational mistakes. Thus it was important to control and characterize its
momentum calibration. While it was not possible to enter a direct particle beam into the sensitive
volume of the TPC to calibrate the detector, a set of physical processes and detector properties
were exploited to achieve a precise calibration of the apparatus. In the following we recall the
main issues concerning the momentum measurement in the HARP TPC, and describe the crosschecks
made to validate the momentum scale. As a conclusion, this analysis demonstrates that the
measurement of momentum is correct within the published precision of 3%.

ABSTRACT: The HARP system of resistive plate chambers (RPCs) was designed to perform particle identification by the measurement of the difference in the time-of-flight of different particles. In previous papers an apparent discrepancy was shown between the response of the RPCs to minimum ionizing pions and heavily ionizing protons. Using the kinematics of elastic scattering off a hydrogen target a controlled beam of low momentum recoil protons was directed onto the chambers. With this method the trajectory and momentum, and hence the time-of-flight of the protons can be precisely predicted without need for a measurement of momentum of the protons. It is demonstrated that the measurement of the time-of-arrival of particles by the thin gas-gap glass RPC system of the HARP experiment depends on the primary ionization deposited by the particle in the detector.

ABSTRACT: The double-differential production cross-section of positive pions, d2sp+/d pdWd^2\sigma^{\pi^{+}}/d pd\Omega, measured in the HARP experiment is presented. The incident particles are 8.9GeV/c protons directed onto a beryllium target with a thickness of 5% of a nuclear interaction length. The measured cross-section
has a direct impact on the prediction of neutrino fluxes for the MiniBooNE and SciBooNE experiments at Fermilab. After cuts,
13million protons on target produced about 96000 reconstructed secondary tracks which were used in this analysis. Cross-section
results are presented in the kinematic range 0.75 GeV/c≤pπ≤ 6.5 GeV/c and 30 mrad≤θπ≤ 210 mrad in the laboratory frame.

S decay mode in the NOMAD νμN data is reported. The special background generation procedure was developed. The proton identification criteria are tuned
to maximize the sensitivity to the Θ+ signal as a function of xF which allows to study the Θ+ production mechanism. We do not observe any evidence for the Θ+ state in the NOMAD data. We provide an upper limit on Θ+ production rate at 90% CL as 2.13×10-3 per neutrino interaction.

ABSTRACT: The recent discovery that neutrinos have masses opens a wide new field of experimentation. Accelerator-made neutrinos are essential in this program. Ideas for future facilities include high intensity muon neutrino beams from pion decay (`SuperBeam'), electron neutrino beams from nuclei decays (`Beta Beam'), or muon and electron neutrino beams from muon decay (`Neutrino Factory'), each associated with one or several options for detector systems. Each option offers synergetic possibilities, e.g. some of the detectors can be used for proton decay searches, while the Neutrino Factory is a first step towards muon colliders. A summary of the perceived virtues and shortcomings of the various options, and a number of open questions are presented.

ABSTRACT: We present a general solution for the problem of reconstructing trajectories and vertexes. This solution has been realized in a C++ toolkit that could incorporate easily different methods for fitting, propagation, pattern recognition and simulation. The RecPack functionality is independent of the experimental setup, what allows to apply this toolkit to any dynamic system.
