“…Each of the four beams from the four accumulator rings will be led to one of the targets. Within EUROν, a beam distribution system downstream of a single accumulator ring to four target stations has already been studied [10]. For ESSνSB a similar system will be studied for the distribution of the beam from the linac to the four rings.…”

“…The ESSνSB (standing for European Spallation Source Neutrino Super Beam) project succeeds the studies made by the FP7 Design Study EUROν [8][9][10], regarding future neutrino facilities, in particular the study made of the CERN based Superconducting Proton Linac (SPL) [11,12] (4.5 GeV protons, 4 MW) Super Beam and the MEMPHYS [13,14] large Water Cherenkov detector in the Fréjus tunnel located at the first neutrino oscillation maximum (130 km). ESSνSB [15] proposes to study a Super Beam, which uses the high power linac of the European Spallation Source (ESS) [16] at Lund in Sweden as proton driver and with a MEMPHYS type detector located in a deep mine at a distance between 300 km to 600 km distance, near the second neutrino oscillation maximum.…”

Very intense neutrino beams and large neutrino detectors will be needed in order to enable the discovery of CP violation in the leptonic sector. We propose to use the proton linac of the European Spallation Source currently under construction in Lund, Sweden to deliver, in parallel with the spallation neutron production, a very intense, cost effective and high performance neutrino beam. The baseline program for the European Spallation Source linac is that it will be fully operational at 5 MW average power by 2022, producing 2 GeV 2.86 ms long proton pulses at a rate of 14 Hz. Our proposal is to upgrade the linac to 10 MW average power and 28 Hz, producing 14 pulses/s for neutron production and 14 pulses/s for neutrino production. Furthermore, because of the high current required in the pulsed neutrino horn, the length of the pulses used for neutrino production needs to be compressed to a few µs with the aid of an accumulator ring. A long baseline experiment using this Super Beam and a megaton underground Water Cherenkov detector located in existing mines 300-600 km from Lund will make it possible to discover leptonic CP violation at 5 σ significance level in up to 50% of the leptonic Dirac CP-violating phase range. This experiment could also determine the neutrino mass hierarchy at a significance level of more than 3 σ if this issue will not already have been settled by other experiments by then. The mass hierarchy performance could be increased by combining the neutrino beam results with those obtained from atmospheric neutrinos detected by the same large volume detector. This detector will also be used to measure the proton lifetime, detect cosmological neutrinos and neutrinos from supernova explosions. Results on the sensitivity to leptonic CP violation and the neutrino mass hierarchy are presented.

“…The opportunities for CERN to host a next-generation super-beam has been studied by the EUROν Framework Programme 7 (FP7) Design Study consortium [44]. EUROν studied a narrow-band beam generated using the 5 GeV, 4 MW Superconducting Proton Linac (SPL) at CERN illuminating the MEMPHYS, 450 kT water Cherenkov detector located in the Laboratoire Souterrain de Modane (LSM) at a distance of 130 km (this option is referred to as CERN-Frejus since the LSM is located in the Frejus tunnel) [45].…”

The νSTORM facility has been designed to deliver beams of ν e and ν µ from the decay of a stored µ ± beam with a central momentum of 3.8 GeV/c and a momentum spread of 10% [2]. The facility is unique in that it will:• Serve the future long-and short-baseline neutrino-oscillation programmes by providing definitive measurements of ν e N and ν µ N scattering cross sections with percent-level precision; • Allow searches for sterile neutrinos of exquisite sensitivity to be carried out; and • Constitute the essential first step in the incremental development of muon accelerators as a powerful new technique for particle physics. The race to discover CP-invariance violation in the lepton sector and to determine the neutrino mass-hierarchy has begun with the recent discovery that θ 13 = 0 [3-7]. The measured value of θ 13 is large (sin 2 2θ 13 ∼ 0.1) so measurements of oscillation probabilities with uncertainties at the percent level are required. For the next generation of long-baseline experiments to reach the requisite precision requires that the ν e N and the ν µ N cross sections are known precisely for neutrino energies (E ν ) in the range 0.5 < E ν < 3 GeV. At νSTORM, the flavour composition of the beam and the neutrino-energy spectrum are both precisely known. The storage-ring instrumentation combined with measurements at a near detector will allow the neutrino flux to be determined to a precision of 1% or better. νSTORM is therefore unique as it makes it possible to measure the ν e N and the ν µ N cross sections with a precision 1% over the required neutrino-energy range.A number of results have been reported that can be interpreted as hints for oscillations involving sterile neutrinos [8][9][10][11][12][13][14][15][16][17][18] (for a recent review see [19]). Taken together, these hints warrant a systematically different and definitive search for sterile neutrinos. A magnetised iron neutrino detector at a distance of 1 500 m from the storage ring combined with a near detector, identical but with a fiducial mass one tenth that of the far detector, placed at 20-50 m, will allow searches for active/sterile neutrino oscillations in both the appearance and disappearance channels. Simulations of the ν e → ν µ appearance channel show that the presently allowed region can be excluded at the 10σ level while in the ν e disappearance channel, νSTORM has the statistical power to exclude the presently allowed parameter space. Furthermore, the definitive studies of ν e N ( ν µ N ) scattering that can be done at νSTORM will allow backgrounds to be quantified precisely.The European Strategy for Particle Physics provides for the development of a vibrant neutrino-physics programme in Europe in which CERN plays an essential enabling role [20]. νSTORM is ideally matched to the development of such a programme combining first-rate discovery potential with a unique neutrino-nucleus scattering programme. νSTORM could be developed in the North Area at CERN as part of the CERN Neutrino Facility (CENF) [21]. Furthermore, νSTORM is capable o...

“…Two types of possible future neutrino beams are considered for oscillation measurements with a water-Cherenkov detector: (i) ''Super-Beams'' [10] are high-intensity neutrino beams generated with a ''traditional'' technique: pions and kaons, produced in accelerated proton collisions on a target, decay in flight giving origin to beams consisting mainly of or , with a contamination from other neutrino species at the percent level and not precisely known; (ii) ''Beta-Beams'' [11,12] are made of neutrinos originated from the decay in flight of accelerated beta emitters (such as 18 Ne or 6 He) and consist purely of e or e with a known energy spectrum. Optimization and cost estimates for these beams have been studied in EUROnu [13].…”

MEMPHYS (MEgaton Mass PHYSics) is a proposed large-scale water-Cherenkov experiment to be performed deep underground. It is dedicated to nucleon decay searches and the detection of neutrinos from supernovae, solar, and atmospheric neutrinos, as well as neutrinos from a future beam to measure the CP violating phase in the leptonic sector and the mass hierarchy. This paper provides an overview of the latest studies on the expected performance of MEMPHYS in view of detailed estimates of its physics reach, mainly concerning neutrino beams
